Thermo-hygrometer MeteoTemp®
The MeteoTemp® probe measures air temperature and relative humidity. It also derives the dew point and frost point. The RH+T+P variant measures the atmospheric pressure as well. The probe has a very low power consumption. Its accuracy, resolution and stability meets the World Meteorological Organization quality standards. It also has a industry-grade lightning and surge protection.
The MeteoTemp® probe is an industry-ready thermo-hygrometer. Its very low electric consumption of 800µA limits overheating, especially when used in a MeteoShield® anti-radiation shield. The sensor is very stable and can be calibrated again if needed.
There are two versions of the sensor: version RH+T outputs temperature, relative humidity, dew point and frost point whereas version RH+T+P additionally outputs atmospheric pressure.
The self-cleaning cap on the probe can be replaced.
MeteoTemp® is resistant to lightning and surge, which makes it suitable for difficult environments and avoids missing on any measurement.
The probe native output is Modbus ASCII or RTU, on a RS-485 link. It's also possible to use a conversion box to convert the Modbus output to an analog output (0-1V). The box measures 98x18x55mm, weighs 50g and can be mounted on a DIN rail.
