This compact, digital Hygro-Thermometer is ideal for field use. Comes with pocket clip, 3-volt lithium battery, and user guide.
This humidity/temperature pen features a dual LCD that can simultaneously display temperature from 14 to 122 degrees F (-10 to 50 degrees C) and humidity from 10 to 90 percent RH with accuracies of ±5 percent RH and ±1.8 degrees F (1 degree C).
This pocket-size unit features a Max/Min memory function that stores highest and lowest readings for both temperature and relative humidity. Data Hold “freezes” the reading on the display for easy viewing, and Auto Off to conserve battery power.
A built-in self-calibration utility allows for field calibrations using the optional RH300-CAL calibration kit that includes two calibration bottles — one bottle uses Sodium Chloride (NaCl) to produce the 75 percent relative humidity reference, and the other uses magnesium chloride (MgCl) for the 33 percent relative humidity standard.
