Vaisala HMD60 Series Duct Humidity and Temperature Transmitter
High-performance duct transmitter for supply and return air in demanding HVAC and light industrial applications. ±1.5 %RH and ±0.1 °C, cast-aluminium IP66 body, 4 … 20 mA, 0 … 10 V, Modbus RTU or BACnet MS/TP.
Description
The duct-mounted HMD60 series uses the latest-generation HUMICAP® R2 sensor with improved corrosion resistance, in a cast-aluminium IP66 housing. It is built for supply and return air ducts, air handlers and CRAH discharge where measurement accuracy and native BMS integration matter.
