PolarXpress XH Sensor
High Accuracy
Wireless Humidity (RH) Sensor
GENERAL DESCRIPTION
The High Accuracy (HA) Wireless Humidity (RH) Sensor
allows you to accurately monitor the relative humidity of
the air within a room or enclosure. It also can record and
chart the temperature value.
FEATURES
• Measures relative humidity with high accuracy.
• Measures temperature in Celsius and Fahrenheit.
• PolarXpress online wireless sensor monitoring and
notification system to configure sensors, view data
and set alerts via SMS text and email.
PRINCIPLE OF OPERATION
The PolarXpress High Accuracy Wireless Humidity (RH)
Sensor measures the relative humidity at the device.
The sensor returns RH and temperature values to the
PolarXpress Online Sensor Monitoring and Notification
System. The system calculates dew point from the data
and stores all three data points in the online system
where the data can be reviewed and exported as a data
sheet or graph. Notifications can be set up through the
online system to alert the user when defined thresholds
have been met or exceeded.
POWER OPTIONS
X Sensors are powered by a replaceable 3.0 V coin cell
battery. The X2 Sensors are larger in size (3” [L] x 2.1”
[W] x 1.2” [h]) and include two long-life AA batteries.
It is recommended that unless you are using the AA
battery solution, you set heartbeat to no faster than one
hour to preserve battery life.
APPLICATIONS
• Cabinet Humidity Monitoring
• Ambient Humidity Monitoring
