Description

The non-contact Raytek Raynger ST81 infrared thermometer has a temperature range of -25 to 1400°F (-32 to 760°C). At only 320g (11 oz), the Raytek Raynger ST81 has a response time of 500msec (95% of reading). This infrared thermometer's simple operation sequence of point, shoot, and read is what makes gathering temperature data easier than ever.

Suited to the most demanding applications, the Raytek Raynger ST81 Pro Plus Infrared Thermometer includes innovative features like extra-bright single-point laser sighting, a wide temperature range, and 12-point data logging. The Raynger ST81 is rugged and durable and includes a jack for an K-type thermocouple. Infrared thermometers from the Raytek Raynger ST81 Series can be tripod-mounted for hands-free operation.

Facility maintenance, HVAC/R systems, food safety, electrical and industrial, and marine maintenance are just some of the areas in which the Raytek Raynger ST81 infrared thermometer can be employed. Other applications include automotive and diesel, asphalt work, and fire safety. Powered by 9V alkaline or NiCad batteries, the ST81 infrared thermometer's target spot sizes at focus point is distance to spot of 50:1 (D:S = 50:1).

Optional nylon holster and RTD contact probe 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 or 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.
