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.

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.

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.

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. To view transmitter wiring diagrams, select a part number and click Product Detail.

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.

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 these screeners to a wall, or add a floor stand.

Warning: These screeners are not intended for medical use.

Take your tank’s internal temperature with these sensors that sit on the outside walls. Since they don’t touch your tank’s contents, they won’t cause contamination or corrode. To attach the sensor to your tank, weld the included studs to your tank's walls, or stick them on your tank using adhesive. Either way you mount them, you don’t need to drill or drain your tank, saving you from scheduled downtime.

These sensors are preconfigured for stainless steel tanks with 1/8"-thick walls. They have internal sensors to record the tank’s thermal conductivity, which is used to calculate your tank's internal temperature. The information is sent through a 4-20 mA signal, so you can read the temperature on controllers and data loggers.

Use communication cords (sold separately) to calibrate these sensors on your computer when your tank isn’t the default thickness or material. Download free software and material presets to help you calibrate the sensor. If you know your tank’s thermal conductivity, you can add another material. The software also lets you monitor and log temperature.
