NB This page assumes that you have already read our introduction to the Instromet range of weather stations and provides more detail on sensor and configuration options for the Climatica station.
Special Offer for Christmas 2016: A FREE rain gauge will be supplied with all Climatica stations ordered during Nov/Dec 2016.
Meet the Climatica
Click on the image above to see a live simulation of the Climatica display. Remember, the physical display is a full 12″ wide (27″ for EWS!).
(NB This simulation is hosted on an external server, which may not always be online – check back later if necessary. The display will update every few seconds, keep watching for a minute or two. Also, the MWD/LCD display is an approximation only – it is difficult to represent this in the simulation with 100% accuracy.)
There are three models or configurations that share the Climatica’s overall architecture and capabilities:
- The Climatica itself, with its large, polished wood case and impressive analogue dials;
- The Executive Weather Station (EWS), which is essentially a Climatica station with a more modern styling and super-sized (686mm – 27 inch – wide) display;
- The Metplus station, which uses all the sensors and control circuitry from a Climatica station but has no display. In this model the data logger must be fitted to the control box to feed data to a PC for processing and display. The Metplus model is therefore totally PC-based;
The most distinctive feature of the standard Climatica display is its three large analogue dials (for wind direction, pressure and wind speed respectively). In addition, an LCD panel — the ‘Multi-Weather Display (MWD)’ — provides a detailed text readout of measurements from the other weather sensors. This Climatica display (or its functionally similar, but even larger EWS version) provides readouts for all sensors that can be attached to the Climatica control box (readings for temperature, humidity, rainfall and sunshine hours appear in the MWD) and therefore the same Climatica (or EWS) display type is applicable to all Climatica configurations .
All Climatica models are supplied with the central control box (see left), which is at the heart of the all the station’s data processing, together with the standard version of the anemometer, but all further sensor and logging options must be specified individually. Most Climatica-compatible sensors follow the standard Instromet pattern of being individually mounted and cabled back to the control box, each via a separate 25m sensor cable, which can usually be extended if required.
The control box is relatively small (225 x 150mm or 9″ x 6″) and accommodates the main processing circuitry along with any optional/supplementary circuit boards such as data logger and USB interface that may be required. With its lid on, the control box is a closed unit, with individual sensor cables entering via cable glands. However, the 12v DC supply from the mains adapter (which supplies power for the entire system, including both sensors and display) also enters the control box via a DC socket and therefore the box as a whole cannot be considered weatherproof. A further 5m cable (which can be extended considerably, if required) feeds data to the Climatica or EWS display.
Overall therefore, while the control box does not need to be postioned close to the display, it does need to be located somewhere within reasonable distance of a mains socket and in a dry area protected from the weather.
Weather sensors available for the Climatica model include:
- Anemometer (wind speed and direction);
- Air temperature (optionally in a miniature Stevenson screen);
- Humidity sensing, which can use one of two distinct sensors
- Combined wet and bulb temperature sensor (readings can be converted externally to humidity and dew point temperature values);
- Electronic humidity sensor;
- Second (auxiliary) temperature sensor (only available if wet bulb humidity sensing is not in use)
- Barometric pressure sensor, which can also be one of two sensor options
- Analogue pressure sensor (integrated into the pressure dial assembly);
- Electronic pressure sensor;
- Sunshine Hours
More details on the various sensor options, specifications and permitted combinations can be found on the Instromet sensors page.
Please note that the pressure dial on the Climatica/EWS display is analogue only and does not pass pressure data back to the control box. An electronic pressure needs to be specified in addition, if there is a requirement to log pressure data.
Climatica – further details
The Climatica station and display are part of the standard Climatica model and therefore as described in the bulk of the notes above, with details on data logger and software included in the Metplus section below. Remember that the case is glass-fronted and the buttons on the right-hand side control the LCD Multi-Weather Display.
The finish of the wood case for the Climatica display can be selected from six options — see below. Sapele is the standard finish; the other finishes are available to order at slight extra cost. See image right for case in a lighter coloured wood finish (click to enlarge).
Executive Weather Station (EWS) details
The Executive Weather Station (EWS) version of the Climatica model is the most impressive unit of all, with the display measuring a full 686mm (27″) wide and 342mm (13″) high. The cabinet is constructed of Sapele wood and then finished with an ultra-stylish polished bezel in stainless steel.
This unit is ideal for wall-mounting (although it will also stand on any suitably generous surface) and the display will be clearly visible from some distance away.
The display is recognisably similar to the main Climatica display and uses all of the same sensors and control circuitry, but the scaling up of the display and the ultra-modern finish add yet more impact and presence to what is already a thoroughly impressive design.
EWS stations can be ordered with all the standard Climatica sensors and options, but of course being careful to order EWS as the main station display.
Data logger (and Metplus) details
The data logger is an additional circuit board that fits inside the main Climatica control box – see image below (top cover removed from the control box and logger is on the rear circuit board). The data logger cables to a PC via a standard RS232 connection, which may be converted to a USB connection via either an external serial-to-USB adapter, or – as an optional extra – an internal USB adapter fitted within the control box.
The Metplus station therefore comprises this standard Climatica control box with logger fitted, plus whatever sensors have been specified when ordering the system. The basic anemometer is included within the standard Metplus bundle, but all other sensors should be individually specified. The Metplus station is not supplied with a dedicated display – the display function would be handled by the PC software and display.
The data logger is broadly similar in function to the Davis loggers, in having two distinct modes of operation:
- The logger can deliver a real-time data stream to a PC with updates as often as every second. This allows a PC display to be showing genuinely live data, including wind speed updates every second;
- When a PC is not connected, the logger can summarise and store the weather data at intervals for later download to the PC. A 2MB memory chip is fitted to the logger that is able to store 32768 error corrected data records (one record containing data from all connected sensors). The logging interval can in principle be set to any integer value between 1-65535 seconds (ie potentially up to 18 hours between records), although the software in use will typically limit the interval options available to a few selections between 1 and 30 minutes, for example. But even at a maximum of 30 minutes, the IM logger will have a capacity of almost 2 years’ worth of data (not that we recommend logging for this long without a download!).
The IM logger has its own real-time clock and so can accurately time-stamp logged data records.
Software recommended for use with this IM logger is the Cumulus program. Cumulus is software that is widely used with many different makes of weather station nowadays and has been specially adapted for full compatibility with the IM logger. Cumulus is state-of-the-art software for weather stations and has an extensive range of features, including the ability to run live weather-reporting websites. Some examples of Cumulus data presentations on both local PC displays and on websites will be found on our Example Screenshots page – be sure to look for the examples that relate specifically to Cumulus. Cumulus is a free download from the author’s website, though donations to assist development of this excellent program are gratefully received.
A revised version of the Met4Net software that has traditionally been used by Instromet stations is currently also in development and may be available at some future date.

Other than mounting accessories, the other main items that purchasers of a station in the Climatica range will need to specify include:
- Additional sensors (remember the basic anemometer is included with the standard Climatica station);
- An alternative wind speed scale, if preferred (MPH/outer and knots/inner is the standard pattern);
- Display case type;
- Data logger (if required);
- Any additional circuit board options (e.g. USB board or adapter, electronic pressure sensor etc);
