The CRL Humidity/Temperature Pen has fast response solid-state sensors, which continuously and simultaneously displays both relative humidity and air temperature (°F/°C) on the 1/2" LCD screen. The Pen records the highest and lowest values in its memory, either overnight or for any duration of time to establish cure rates. Operates with one 1.5V battery.
The pen reads a temperature range from 32.0 to 122.0°F (0.0 to 50.0°C), with a resolution of 0.1% and an accuracy of 1°C. It has a relative humidity range from 2 to 98%, with a resolution of 1% and an accuracy of 2% (mid-range) to 4% (end-of-range). The display shows changes in less than 30 seconds, and is updated every second. This is an indispensable tool for any windshield installer. Supplied with two silver-oxide batteries.
