testo 177-H1

Climate cabinets are dependent on stable humidity and temperature measuement values. Reliable recording and documentation of climate values (%RH, °C and °Ctd) are possible with the data logger 177-H1

An additional surface, immersion or air probe can be connected to the data logger.

• 1 x internal %RH/°C/°Ctd + 1 x external °C

• Long-term stable humidity sensor with fast response time

• Memory for 48,000 readings

• Control and adjustment option with adjustment set

• Protection caps for dirt-ingressed or corrosive gases
