  • Accuracy H.: ± 1,5 % RH
  • Accuracy T.: ± 0,15 K
  • IP64
  • With exchangeable digital measuring head (PM-U)
  • No interruption of the measurement process

PMU-P

  • Operating temp. up to 70 °C
  • Accuracy F. (25 °C): ± 1,5 % RH
  • ASCII-Protocol (3,3 V DC)

All transmitters of the Plug‘n‘ Measure Series work with an internal hx processor which uses the measured values for relative humidity and temperature to also calculate enthalpy, absolute humidity, mixture ratio (water/air) or wet-bulb temperature.

No interruption of the measurement process
When it‘s time to re-calibrate the transmitter, the measuring heads (PMU) can be switched within seconds, allowing processes to run continuously with virtually no interruption.

Capacitive humidity sensor
Use of capacitive humidity sensor elements is a guarantee of high long-term stability, resistance to dew formation, small hysteresis and good dynamic performance.
