 The Raytek Raynger ST20 Pro is the professional’s choice for value and precision. This non-contact Raytek infrared thermometer offers accurate readings in a compact and reliable design.
Infrared thermometers from the Raytek Raynger ST20 Pro Series have a user selectable temperature range of -25 to 999°F (-32 to 535°C), a 500 msec reading response time, and a weight of 11 ounces. This infrared thermometer is safe to use as it requires no contact with the surface measured so long as it is within the thermometer’s range (D:S=12:1). The Raytek Raynger ST20 has a preset emissivity of 0.95.
With extra-bright single-point laser sighting, a MAX temperature display, and rugged rubber overmolding, the Raytek Raynger ST20 Pro infrared thermometer can prevent downtime by permitting preventative and predictive maintenance by simply pointing, shooting, and reading temperature measurements. This thermometer is perfect for automotive and diesel applications, facility maintenance, fire safety, marine maintenance, electrical, industrial, asphalt work, and HVAC systems, and these are just a few of the applications in which the Raytek Raynger ST20 infrared thermometer can be utilized.
Optional nylon holster sold separately.
Infrared Temperature Measurement - Technology Explained
Infrared thermometers measure temperature from a distance by detecting the amount of thermal electromagnetic radiation emitted from the object being measured. This allows users to accurately measure surface temperatures in hazardous, hard-to-reach places, or other situations in which non-contact temperature measurement is desirable. Infrared thermometer technology is useful in a wide range of applications – including industrial, laboratory, food service, fire fighting, hobby, and home use.
While the technology is relatively simple, the myriad of names given to these devices can be confusing. “Laser Thermometers” makes reference to the laser that helps aim the thermometer. “IR Sensors” and “IR Thermometers” make use of a common abbreviation for “infrared”. “Non-Contact Thermometers” is descriptive of the device’s ability to measure temperature from a distance. “Radiation Pyrometers” is a scientific/technical term for these devices.
