Vaisala HMP155 Humidity and Temperature Probe | Hinco Perth

The Vaisala HMP155 humidity and temperature probe delivers highly accurate, long-term stable measurement of relative humidity and temperature for demanding outdoor and industrial applications. Built around Vaisala’s proven HUMICAP®180R sensor, the HMP155 is a trusted choice for meteorology, aviation, road weather and environmental monitoring across Australia.

Accurate humidity and temperature in harsh conditions

The HMP155 measures relative humidity across 0–100 %RH and temperature from −80 to +60 °C, holding ±1 %RH accuracy even in fog, condensation and rapidly changing conditions. An optional warmed probe and chemical purge keep readings reliable in high-humidity and chemically contaminated environments, while the IP65-rated housing withstands continuous outdoor exposure.
