Click2Contact

Vaisala’s HMT120 and HMT130 humidity transmitters are designed to enable accurate measurements with good long-term stability. These multi-purpose transmitters with exchangeable measurement probe are a suitable choice for cleanrooms and other demanding HVAC applications.

Features include: ±1.5%RH, ±0.1°C/±0.18°F accuracy; the option to be wall-mounted, duct-mounted with a kit, or outdoors with a shield; the probe can be attached direct to the transmitter or using a cable; analog output options 0–10 V/ 4–20 mA (loop powered); optional parameters (dew point/frost point, wet bulb, enthalpy, absolute humidity, mixing ratio); and traceable calibration (certificate included).

Humidity measurement with the Vaisala HUMICAP 180R humidity sensor enables state-of-the-art precision, stability and environmental resistance, the company says. Temperature is measured with a Pt1000 sensor element, designed to be highly accurate. The high quality and stability of the measurements should enable precise control of HVAC systems, even in demanding conditions or sites.

The instruments are individually adjusted and delivered with a traceable (ISO 9001) calibration certificate. The humidity transmitter is easy to calibrate onsite using a Vaisala handheld meter or Vaisala Insight PC software.
