The analog Vaisala HMS112 Humidity and Temperature Transmitter is designed for accurate humidity and temperature measurements outdoors. HMS112 includes an integrated radiation shield to protect the sensor from solar radiation and rain.
With RH accuracy of ±2 %RH, the humidity and temperature transmitters have been calibrated with 3-point NIST traceable calibration (certificate included).
The Vaisala HMS112 transmitter is equipped with the proven HUMICAP® 180R sensor. The sensor’s superior long-term stability minimizes maintenance needs throughout the transmitter’s lifetime. If necessary, the transmitter can be field-calibrated using either an HM70 Hand-Held Humidity and Temperature Meter, or a PC connection.
The HMS112 model includes the following:
• Relative Humidity Measurement 0...100%
• Temperature Measurement -40 ... +60 °C (-40 ... +140 °F)
• Loop-powered, 4...20mA analog outputs
• 24V input voltage
• Integrated rain/radiation shield
• Mounting hardware
