Measure the temperature of dangerous, hard-to-reach, and moving surfaces without risking electrical shock or contamination. These thermometers 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 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.

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.

Add accessories to protect your infrared thermometer transmitter 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. Cooling jackets connect to a compressed air or water line to keep temperature transmitters from overheating. 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.

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.

Quickly take people’s temperatures as they enter your facility to screen out anyone with a high reading. These screeners have a thermal camera that uses infrared light to measure forehead temperature in two seconds at a distance of one to two feet. They’re accurate within 0.9° F and 0.5° C, and work even if people are wearing masks, hats, and glasses. If their temperature is normal, there’s an audible notification. Connect them to your network using Wi-Fi or their ethernet port in order to create a library of photos, retain data for reporting, and customize the screeners to display directions and your company name and logo. For basic temperature scanning only, there’s no need to connect them to your network—simply plug their power cord into a wall outlet. If you want to keep people from entering until they pass the temperature check, wire these screeners to doors and gates. CE marked, they meet European safety, health, and environmental protection requirements.

Mount them to a wall, or add a desk stand or floor stand.

Warning: These screeners are not intended for medical use.

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.

Control lights on a single circuit from more than one motion-sensing switch. Also known as occupancy sensors, these controls turn lights on when movement is detected and off when an area is unoccupied. The infrared sensors detect changes in heat sources and require a direct view of the occupants. Use up to four controls on the same circuit to detect motion in large rooms. All have a time delay to turn lights off after a set time.

Rated IP65, these controls are protected from washdowns. Also known as occupancy sensors, they turn lights on when movement is detected and off when an area is unoccupied. The infrared sensors detect changes in heat sources and require a direct view of the occupants. All have a time delay to turn lights off after a set time.

Mount these controls directly to a light fixture. Also known as occupancy sensors, they turn lights on when movement is detected and off when an area is unoccupied.

A chime announces when someone passes through the infrared light beam and a counter keeps track of each entrance and exit. Mount the transmitter and beam reflector between 2 and 20 feet apart. The chime's volume is adjustable up to 85 dB. It cannot be sold to California due to local energy efficiency regulations.

Additional chimes (sold separately) can be added to the transmitter.
