Measure and receive alarms on dew point User selectable dew point measuring ranges: -22° to 122°F (-30° to 50°C), -4° to 104°F (-20° to 40°C), or 32° to 122°F (0° to 50°C) Weatherproof enclosure allows device to be placed outdoors Set high and low limits by programming the Sensaphone Sensaphone will go into alarm when dew point exceeds limit The Sensaphone Dew Point Sensor will measure and provide real time dew point values to any Sensaphone that accepts a 4-20mA signal. When the dew point level falls outside of the Sensaphone’s programmed high or low limit, the user will receive an alarm which displays or reads the current dew point value. The sensor comes enclosed in a weatherproof enclosure that is suitable for use in outdoor environments. A 24V DC power supply is required to power the sensor.
