INTRODUCTION
Thank you for purchasing General Tools & Instruments' IRT850K 50:1 Ultra-Wide Range IR
Thermometer with "K" Port. Please read this user's manual carefully and thoroughly before using
the instrument.
The IRT850K is a specialized instrument that can measure the temperature of a very hot or cold
object or surface (the target) by using an IR sensor to measure its thermal radiation from a safe
distance. Dual laser beams help define the size of the target. With a distance-to-spot (D:S) ratio
of 50:1; the IR sensor can measure the temperature of a target (spot) 1 ft. in diameter from 50 ft.
away with a basic accuracy of ±1.8°F near room temperature and an accuracy of ±(2% of the
reading or 3.6°F) elsewhere in the measurement range. The IRT850K's IR measurement range is
-76° to 2732°F (-60° to 1500°C).
The IRT also has a socket for an optional "K" type thermocouple probe with a measurement
range as wide as -83.2° to 2552°F (-64° to 1400°C).
The IRT850K is designed for use in heavy industrial sectors such as steel and chemical
manufacturing, petroleum refining, steam generation, and power generation and transmission.
