For IR calibrations above normal ambient, the 9132 provides a steady blackbody target up to 500degrees Celsius (932degrees Fahrenheit). With precision to plus or minus0.5degrees Celsius and stability to plus or minus0.1degrees Celsius, this new portable IR unit can certify most handheld pyrometers. Short heating and cooling times mean you won't have to wait extended periods of time to get your work done. From room temperature to 500degrees Celsius the 9132 will be stable within 30 minutes. You won't find a more compact IR calibrator. Range: 50 to 500degrees Celsius (122 to 932degrees Fahrenheit)
