Keep these small thermometers in your pocket or toolkit to spot check the temperature of dangerous, hard-to-reach, and moving surfaces without touching them. Maximum working distance is the distance a one foot target can be reliably measured.

Thermometers with adjustable emissivity can be calibrated for more accurate readings of shiny surfaces than thermometers with fixed emissivity.

Thermometers with laser sight have a red beam of light to indicate the precise area being measured.

Thermometers with Bluetooth wirelessly send temperature results to an app downloaded to your smartphone. Use the app to adjust the emissivity.

Warning: These infrared thermometers are not intended for medical use.

To confirm the accuracy of noncontact temperature readings of dangerous and inaccessible surfaces, these thermometers come with a calibration certificate traceable to NIST that states they’ve passed a test for accuracy. Maximum working distance is the distance a one foot target can be reliably measured.

Thermometers with adjustable emissivity can be calibrated for more accurate readings of shiny surfaces than thermometers with fixed emissivity.

Warning: These infrared thermometers are not intended for medical use. Use Non-Contact Forehead Thermometers for medical use.

Detect hot spots, leaks, moisture problems, and construction defects invisible to the eye. These imaging guns translate thermal energy into a color image that indicates hotter areas as brighter and cooler areas as darker, so it’s easy to identify and diagnose problems on instrument panels, HVAC systems, and other equipment. To review footage at a later date, use them to take photos and videos. The lower a camera’s thermal sensitivity, the more precise heat differences it will detect for more detailed images. All are CE marked as meeting European standards for health, safety, and environmental protection. Some include a calibration certificate traceable to NIST stating they’ve passed a test for accuracy.

These thermometers are rated for environments where hazardous material is present. They measure the temperature of surfaces without making contact and are often used to locate and diagnose problems in electrical, heating, and ventilation systems. Maximum working distance is the distance a one foot target can be reliably measured. Thermometers have adjustable emissivity, which means they can be calibrated for accurate readings of shiny surfaces.

Hazardous location environmental ratings indicate whether manufacturers have included safety features in products to facilitate their safe use in a hazardous environment. Before selecting a product for a hazardous location, ensure it is rated for your environment. See About Hazardous Location Environmental Ratings.

Use these accessories to protect your infrared thermometer transmitter and keep it working properly in hot or dirty environments.

Air purges flush out dust, moisture, and other contaminants on transmitter lenses that can interfere with infrared radiation focus and cause inaccurate readings. Connect them to a compressed air line to use.

Cooling jackets connect to a compressed air or water line to keep temperature transmitters from overheating. They’re recommended for use if operating in environments over 149° F.

Protective covers prevent dirt buildup and excessive exposure to light, which can cause transmitters to lose focus.

Insulating tubes prevent overheating by protecting thermometers against heat from mounting brackets or other surfaces.

Monitor the temperature of molten steel, furnaces, glass, and other hazardous surfaces without touching them. A built-in transmitter reads surface energy levels and converts them to analog and digital output values that can be read by a receiving device, such as a PLC. Because of this, you can use these transmitters for measuring and switching applications.

Adjust set points, emissivity range, and other settings on-site using the buttons on the transmitters. Connect transmitters to an IO-link controller (not included) to change settings remotely and alert you to errors on PLCs and human-machine interfaces.

Plug these transmitters into shielded M12 sockets since they're extremely prone to signal interference. These transmitters connect using two wires to send a 4-20mA current output and four wires to use the switching output and IO-link. Connect to pin 5 to utilize the test function to verify that the transmitter's signal processing is working correctly.

Their lenses resist scratches, which could cause transmitters to lose focus. All are IP-rated for protection against dust and low-pressure jets of water. Made of 303 stainless steel, these transmitters resist corrosion.

Transmitters can be used on all surfaces. For best results when measuring at an angle or working on round or uneven surfaces, use transmitters with laser sight.

Transmitters with a wavelength range of 0.78–1.06 microns are best for use with glass. Use transmitters with a wavelength range of 1–1.7 microns on metal, ceramics, and graphite. Transmitters with a wavelength range of 8–14 microns are useful for plastic, fabrics, food products, and other metal-free surfaces.
