Infrared Thermometers with Calibration Certificate
Ensure the accuracy of noncontact temperature readings of dangerous and inaccessible surfaces with these thermometers that 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.

Thermal Imaging Cameras
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.

Hazardous Location Infrared Thermometers
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 with adjustable emissivity can be calibrated for more accurate readings of shiny surfaces than thermometers with fixed emissivity.
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.
Warning: These infrared thermometers are not intended for medical use. Use Non-Contact Forehead Thermometers for medical use.

Non-Contact Temperature Screeners
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.

Wireless Thermocouple Transmitters for Liquids and Gases
Monitor your system’s temperatures directly from your smart device. These battery-powered transmitters send real-time measurements to smartphones and tablets via Bluetooth, so you can easily confirm your processes are functioning properly. Good for route-based monitoring and preventative maintenance, they record measurements on your smart device and send alerts if equipment requires your attention. Use them to maintain a safe distance from your process or to stay out of a dirty environment. Install the app to set your parameters, choose how often you’d like to receive data, and monitor temperatures from up to 300 ft. away. Rated IP65, they’re protected against dust and washdowns.
Strap-mount transmitters can be installed almost anywhere with the included cable tie, so they’re good for equipment that might not have a threaded port available. However, because they mount externally, they are less accurate than threaded-mount transmitters.
Turn your transmitter into a portable monitoring system by adding a quick coupling (not included). This lets you make fast, temporary connections to various equipment in different locations.
