MeteoTemp | Digital Sensors

MeteoTemp provides Air Temperature, Humidity, Barometric pressure, dew point & frost point meteorological measurements. This sensor has been proven to provide one of the lowest measurement uncertainties in the market.


MeteoTemp comes in two variants :

  • MeteoTemp RH+T offering Air Temperature, Humidity, dew point and frost point.
  • MeteoTemp RH+T with Pressure offering additional Barometric Pressure with Air Temperature, Humidity, dew point and frost point.

Unique Features & Benefits

  • Ultra- low power consumption of combined 800 µA, 5x less than other meteorological temperature and humidity probes in the market.
  • Eliminates self-heating from your measurements.
  • World Meteorological Organization (WMO) Temperature measurement accuracy
  • World Meteorological Organization (WMO) Humidity measurement accuracy


  • Stable long-term temperature and humidity.
  • Excellent value with easy re-calibration and traceability features.
  • Versatile industrial interface : MODBUS ASCII & RTU
  • Three stage industrial surge and lightning protection including, transient, EMI, and ESD

Advantages of MeteoTemp

1. Replaceable PTFE filter cap

Self-cleaning Teflon material keeps the measuring element clean. These are field replaceable micro-porous filter cap offering long term dirt resistance, offering fast sensor response due to high pore density and efficient transport.

2. Ultra-low power consumption

MeteoTemp offers Ultra-low power consumption. This not only increases the accuracy but also extends weather station’s battery life. MeteoTemp's power consumption is 5x lower that the meteorological industry average for digital temperature and humidity sensors.

3. Lightning Protection

MeteoTemp offers 3-stage lightning protection complemented by the RS-485 digital output which has inherently high resistance to interference and is therefore most widely used communication interface in tough industrial environments.

Lightning protection meets the following international standards for industrial equipment safety:

  • EMC Emissions according to EN50081-1 / IEC61000-6-1
  • EMI Transients according to EN50081-1 / IEC61000-6-2
  • SURGE test 4 kV / 2 kA EN50082-2 / IEC61000-6-2
  • ESD 15000 V (15 kV)

4. Clean Sensors – Helical design MeteoShield
