HMD60 temperature and humidity transmitter

User 's Manual

All the common humidity parameters are in HMD60 can be selected: dew point, wet bulb, enthalpy value, absolute humidity, mixing ratio. All of these parameters can be selected using the DIP switch. Easy field adjustment can be made by using high accuracy fine-tuning capacitor or hand-held wet thermometer MH70.The transmitter can also be configured using computer software. The precision, stability and reliability of the product line make it ideal for museums, clean rooms and laboratories. The product is equipped with a traceable calibration certificate.

Both design, stable and reliable:The transmitter's all-metal housing is ideal for use in construction and industrial environments. The HMD60 series provides excellent stability and resistance to environmental chemical contamination due to the use of Vaisala HUMICAP® R2 sensors. Measuring accuracy up to ±1.5 %RH and ±0.1 °C (±0.18 °F). All common humidity parameters are available, including relative humidity, dew point, enthalpy, and wet bulb temperature.

Quick field calibration:The accuracy of the transmitter can be easily checked with the Vaisala hand-held meter HM70. A simple potentiometer can be used to calibrate in seconds without interfering with operation, saving maintenance time and significantly reducing costs.

Availability:The HMD60 series can be easily configured by the Visala Insight computer software at user application time or at the factory. The electronic components can be removed separately, eliminating the need to remove the entire unit from the pipe. These products can be configured using the Vaisala Insight computer software.
