High Accuracy Humidity & Temperature Transmitter - Wall Mounted With Display HMW90

The Vaisala HMW90 Series has been complemented with four new models: TMW92 and TMW93 temperature transmitters for applications where only temperature measurement is needed and the configurable HMW90 and TMW90 for special scalings.

The HMW90 and TMW90 transmitters are available in four color options: standard white, black, grey and ivory.
