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.

Noncontact Infrared Temperature Sensors
Monitor the temperature of hazardous, sensitive, and hard-to-reach surfaces without touching them. IP or NEMA rated, these sensors are protected against dust and washdowns.
Sensors for nonmetal surfaces measure the temperature of plastics, fabrics, ceramics, and hot adhesives.
Sensors for metal surfaces measure the temperature of both solid metals, such as heating elements, and molten metals.
Sensors with a thermocouple output communicate with devices that read thermocouple signals, so they work as replacements for thermocouples with the same output type.
Sensors with a micro USB cord and terminal block connect to your computer. Use the downloadable software to change the measurement temperature range and the output scale.
Secure your sensor with a mounting bracket or mounting stud. Mounting brackets attach to flat surfaces. Mounting studs thread into holes.
Air purges flush dust, moisture, and other contaminants from the sensor lens to prevent inaccurate readings.
