Hart Scientific 4180/4181 Infrared Calibrator
|
The Hart Scientific 4180/4181 infrared calibrator features a large, six inch target designed to accommodate the field of view and calibration geometry requirements of common infrared thermometers that will not accurately test with smaller targets. The Hart Scientific 4180 infrared calibrator has a temperature range from –15°C to 120°C while the 4181 infrared calibrator has a temperature range from 35°C to 500°C.
The LCD display of the Hart Scientific 4180/4181 infrared calibrator continuously shows the current temperature. The temperature may be easily set with the control buttons to any desired temperature within the specified range. A unique safety feature shows the user when the target temperature is above 50°C letting the user know when it is safe to place the target cover on the instrument and/or move it to a different location. The Hart Scientific 4180/4181 infrared calibrator's indicator remains illuminated when the instrument is energized and above 50°C, but with mains power removed, it will flash until the target temperature drops below 50°C. This feature makes the Hart Scientific 4180/4181 infrared calibrator the safest IR calibrators available. |
The precision Hart Scientific 4180/4181 infrared calibrator is enough to use in the field and accurate enough to use in the lab. High accuracy, advanced features, and versatility makes the Hart Scientific 4180/4181 infrared calibrator the perfect solution for testing and calibrating any infrared thermometer or thermal imager within its temperature range. 
The Hart Scientific 4180/4181 infrared calibrator's uniformity and stability ensure that variations can't be detected with a thermal imager. In addition, with accuracies as good as ±0.35°C, the Hart Scientific 4180/4181 infrared calibrator can meet its specifications without additional emissivity-related corrections, leading to legitimate test uncertainty ratios (TUR) as good as 4:1.
