Agency Approvals: CE. The Model TH2-10 Thermo-Hygrometer Pen is a compact handheld device that
measures temperature, humidity, dew point, wet bulb, and heat index. For
increased accuracy, calibration salt baths can be used to field calibrate the
humidity sensor before taking measurements. Minimum, maximum, and average
readings can be displayed on the large 4 digit LCD display. High and Low alarms
provide audible and visual indication of changes to the ambient humidity.
FEATURES
1) Temperature and relative humidity measurement.
2) Calculate dew point temperature and wet bulb temperature.
3) Calculate heat index and wet bulb global temperature.
4) Hi Temperature alarm setting (Heat Index/WBGT).
5) Data hold & Maximum/Minimum/Average function.
6) Auto power off function.
7) Self-calibration by salt bottle (Optional) at 33% & 75% humidity points.
8) Quick response and high accuracy.
