Digital Humidity Module HMM105 is an open frame module for integration into environmental chambers. The modules provide an I2C output for relative humidity (RH) or dew point (Td). The module consists of a detachable probe assembly – a probe head with M10x1 threads and a flex cable – and the module circuit board. The probe assembly is 30 cm in length. The module incorporates the HUMICAP 180R sensor which ensures excellent measurement accuracy.

Benefits

• Easy installation
• Excellent measurement accuracy
• Maintenance-free

Reliable for OEM’s

The HMM105 probe head works in freezing conditions (-40 °C) and also in temperatures up to +180 °C in continuous use. In short-term use, the probe head can be exposed to temperatures up to +200 °C. HMM105 is intended for OEM chamber manufacturers for integration into test chambers and incubators.

I2C interface for better usability

HMM105 has an I2C interface for communicating with the incubator’s controller. HMM105 implements I2C slave functionality, with the incubator’s controller acting as the master. The interface can be used to read measurement values and status information, set operation parameters, and make adjustments.

Maintenance free

Compared to psychrometers, HMM105 is practically maintenance-free. There is no wick that needs changing and there is no need for a water tank or water pump. Thus, environmental stress screening can be done reliably.

Applications

An open frame module for integration into environmental chambers and incubators. The module incorporates the Vaisala HUMICAP 180R sensor which ensures excellent measurement accuracy. A reliable choice for OEM use.
