The Vaisala HMP373 is the short-probe HMT370EX variant for humidity and temperature measurement inside tanks, vessels and other confined, hard-to-reach spaces in hazardous areas.
The Vaisala HMP373 is the short-probe variant of the intrinsically safe HMT370EX range, built for humidity and temperature measurement in confined spaces — inside tanks, vessels, reactors and other tight or hard-to-reach locations where a full-length probe won’t fit.
Its compact form and HUMICAP® sensor give stable readings in enclosed process volumes, with ATEX/IECEx (Ex ia) approval for classified zones in chemical, pharmaceutical, mining and oil-and-gas facilities.
The HMP373 connects to the Vaisala HMT370EX transmitter — see the HMT370EX series datasheet (PDF). Hinco Instruments is your authorised Vaisala distributor in Perth, WA.
