The Vaisala HMP371 is the general-purpose probe in the intrinsically safe HMT370EX range, for wall- and duct-mounted humidity and temperature measurement in industrial and hazardous-area installations.
The Vaisala HMP371 is the general-purpose probe in the intrinsically safe HMT370EX range, for wall- and duct-mounted humidity and temperature measurement in everyday industrial and hazardous-area installations. Where a process doesn’t demand a specialised high-temperature, high-pressure or high-humidity probe, the HMP371 is the standard choice.
It uses Vaisala’s HUMICAP® sensor for stable, low-drift performance and carries ATEX/IECEx (Ex ia) approval for classified zones in mining, manufacturing and general process industries.
The HMP371 connects to the Vaisala HMT370EX transmitter — see the HMT370EX series datasheet (PDF). Hinco Instruments is your authorised Vaisala distributor in Perth, WA.
