HMT335 Humidity and Temperature Transmitter with Remote Probe (5 m Cable) for Temperatures Up to +180°C (+356°F), 1%RH accuracy

The HMT335 is a top-of-the-line versatile instrument with a stainless steel probe designed to withstand high temperatures. The HMT335 is ideal for duct measurements as the probe tolerates mechanical stress and withstands high flow rates. For example, the HMT335 can be used in hot drying processes. The Vaisala HUMICAP® Humidity and Temperature Transmitter HMT330 series incorporates Vaisala’s 40 years of experience in industrial humidity measurement.

The instrument offers a wide variety of different psychrometric units, including dew point, enthalpy, wet bulb temperature, absolute humidity, and mixing ratio.
