Vaisala Multi-Probe Thermohygrometer

Dual probe input for multi-parameter measurement

Vaisala HM70 series meter measures temperature and humidity, plus calculates dew point, wet bulb, mixing ratio, absolute humidity, enthalpy, and water vapor pressure. It offers six different languages in display. Log three parameters into meter memory while displaying data in numerical or graphical fashion. View graphic trends of any parameter on the backlit LCD.

Customize your application with three humidity probes (sold separately). The general-purpose probe measures ambient conditions. Use the 12” stainless steel probe for air duct measurements. The extension cable probe includes a humidity sensor at the end of a 5-meter cable for high-temperature and hard-to-reach measurements. Order probes separately.
