Scientific Hygrometers

Heat Stress Index measures how hot it feels when humidity is combined with temperature, air movement, and radiant heat Black Globe Temperature (TG) monitors the effects of direct solarradiation on an exposed surface Air Temperature (TA) plus Relative Humidity (RH) Selectable units of °F and °C...

Extech's RH35 monitors Humidity, Temperature, and Dew Point for the previous 24 hours and alerts users to indoor mold hazard conditions starting with a frown icon warning when humidity reaches 60%RH. When the RH exceeds 65%, a loud audible alarm and bright flashing red LED will be triggered. The...

20 ~ 100% RH scale on 4" dial. Uses a precise synthetic hair hygrometer with an accuracy of ±5%. Inner dial shows temperature using a bimetal thermometer, with an accuracy of ±2°F. N.I.S.T. traceable certificate of compliance available: 736920C

Relative humidity range is 1 to 99% Resolution is 0.1% RH Accuracy is ±4% RH between 35 to 75%RH, ±5%RH otherwise Humidity features include dew point/wet bulb functions, minimum/maximum memory and high/low alarms Temperature range is -40 to 158°F and -40 to 70°C Temperature...

The RHM16 is a Miniature Hygro-Thermometer ideal for monitoring Temperature and Humidity conditions in enclosed or open space environments. It helps gauge proper heat and moisture levels and it also records high and low extremes during the day. Simultaneous display of Temperature and Humidity...

The CTH10 is an attractive wall clock features an oversized 4.3" (109mm) digit time display that can be easily view from a longer distance than regular sized clocks. It receives Time Code from NIST Radio Station WWVB and it automatically adjusts year, date, day, hour, minute, second, and...

The RH200W-T is a transmitter for Extech's RH200W Hygrothermometer base station. Sync up to 8 transmitters to the base station for continuous monitoring. Transmitters can be up to 98 feet from the base station. Includes a transmitter and 2 AA batteries.

When temperature exceeds your minimum or maximum setting entire display flashes red. Simply hold the IR gun, press the trigger and aim the laser guide at the target. Results immediately appear in ºC or ºF on the backlit LCD and are automatically held for 6 seconds after the trigger is...

Large 3 3/16” x 2 1/2” dual display Recall min/max temperature and humidity readings Stand or wall mount Monitor can be used in labs, chemical storage areas, clean rooms, stock rooms, factories or outdoors. Unit can be used to monitor desiccators, incubators, refrigerators and fume...
