Temperature & Humidity Instrumentation


Take the hassle out of testing with these temperature and humidity instrumentation products. Sturdy and easy to use, these instruments enable fast, effortless testing in any environmental condition. Select the right testing tool for your business from brands such as Reed and Digi.

Precise Readings
Built with sensitive testing surfaces, these temperature and humidity instrumentation tools provide an accurate reading in any setting. Select a heat stress meter with a large globe to measure radiant sunlight and humidity, or opt for an infrared thermometer gun to take the temperature of hot surfaces without physical contact. Many of these tools use digital screens to provide a precise reading.

Multiple Testing Options
Many of these temperature and humidity instrumentation products are engineered to read a single condition, so you can enjoy efficient operation and high performance. Use a resistance thermometer in industrial settings that require careful temperature measurements for safe operation. Alternatively, test multiple factors with a multi-function thermo-hygrometer or psychrometer.

Fast Testing
Built with intuitive button designs and easy-to-read screens, these temperature and humidity instrumentation tools allow quick readings. Simply place the tool or probe in place, activate the sensor and wait for a reading; these instruments require no complex programming. Many tools come with calibration settings to ensure accuracy on the first try.

Convenient Accessories
Keep your temperature and humidity instrumentation products functioning in the field with convenient accessories. Condition-specific probes allow exact readings of interior and surface conditions, and replacement wicks keep your meter running during long days of testing. Testing kits come with a variety of probes and parts, so you can be prepared for any situation.
