The microprocessor-based Vaisala HMP235 HUMICAP Humidity & Temperature Transmitter is a versatile, easy to use transmitter. The Vaisala HMP235 is useful for demanding industrial and air conditioning applications. The transmitter measures relative humidity and temperature. It also outputs dewpoint and wet bulb temperature, mixing ratio and absolute humidity as calculated variables. The Vaisala HMP235 transmitter can be configured to the customer's requirements on the production line, but configuration and parameters can also be set by the user. Both analog and serial outputs are available as well as several options: different cable lengths, power supply modules, serial interface modules and a local display.
