The Vaisala HMP375 is the high-temperature HMT370EX probe for humidity and temperature measurement in dryers, ovens and other heat-intensive processes in hazardous areas.
The Vaisala HMP375 is the high-temperature variant of the intrinsically safe HMT370EX range, made to measure humidity and temperature in hot processes such as dryers, ovens, furnaces and heat-intensive process areas where standard probes cannot operate.
Its heat-tolerant construction and HUMICAP® sensor keep readings stable at elevated temperatures, with ATEX/IECEx (Ex ia) approval for classified high-temperature zones in manufacturing, pharmaceutical and petrochemical plants.
The HMP375 connects to the Vaisala HMT370EX transmitter — see the HMT370EX series datasheet (PDF). Hinco Instruments is your authorised Vaisala distributor in Perth, WA.
