High-precision temperature and humidity transmitter 'testo 6681'

High precision 3-channel output at 1% RH humidity! Pressure dew point probe down to -60℃.

The "testo 6681" is a temperature and humidity transmitter designed for applications that require strict environmental conditions. It offers a measurement accuracy of 1% RH and can meet the stringent demands of high humidity environments where condensation may occur, H2O2 sterilization environments, and pressure dew points. It supports not only analog output but also Ethernet and Profibus. Additionally, we also offer the differential pressure transmitter "testo 6321," which is suitable for compact air conditioning management. 【Features】 ■ High-precision digital probe with humidity ±1% RH and temperature ±0.15℃ ■ Up to 3-channel analog output ■ Outputs: temperature, humidity, absolute humidity, dew point, mixing ratio, mole fraction, wet bulb temperature, enthalpy, water vapor partial pressure, H2O2 mixed dew point ■ Measurement of sterilization environments possible with H2O2 filter ■ Pressure dew point probe down to -60℃ *For more details, please download the PDF or feel free to contact us.
