  • Display and Transmit Temperature and Humidity
  • Two Configureable Analog Outputs (0-10V or 4-20mA)
  • Calculates Seven Other Psychrometric Properties
  • Configure via USB or Keypad
  • RS485 Modbus RTU Communications
  • Wide Backlight Display
  • Alarm Output and Built-In Buzzer

The RHT Climate is a high precision temperature and humidity transmitter.  With a wide backlit LCD and distinctive design, the RHT Climate provides highly accurate and stable measurements over a wide operating range. Being a microprocessed device, it allows full configuration via the front touch pad or the USB or RS485 interface via a Modbus RTU commands.

Apart from the temperature and relative humidity values, which are read directly from the sensor, the transmitter calculates the value of the following psychrometric properties:
• Dew Point Temperature
• Wet Bulb Temperature
• Absolute Humidity
• Frost Point Temperature
• Specific Enthalpy
• Partial Vapor Pressure
• Mixture Ratio

The RHT Climate has two analog outputs which may be programmed for 0-10 V and 4-20 mA. Any variable read by the sensor or calculated by the device can be transmitted via one of the two available analog outputs.

The RHT Climate also has two digital alarm outputs and an embedded buzzer for sound alarm which can be  triggered by any variable read or calculated.

A free downloadable Windows software program, NXperience, is available which provides configuration of all the resources of the device, as well as the diagnosis of the analyzed information.
