Fluke 59 Max Infrared Thermometer, -30C to 350C, Thermopile 8-14m. This IR Thermometer is precision-engineered to provide accurate readings in a range of -30 to 350 deg C/-22 to 662 deg F. Most IR thermometers have a maximum measuring distance of approximately 100 feet (30 meters), depending on atmospheric conditions. Measurements for voltage, resistance, diode, capacitance, frequency, duty cycle and, if available, temperature.
ennoLogic – eT650D. The ennoLogic – eT650D proved to be the most consistently accurate infrared thermometer and is our choice for best overall. It has dual-laser technology with a 10:1 distance-to-spot ratio. Its temperature range is -58 ℉–1202 ℉, one of the broadest of the thermometers we tested. For example, an accuracy of ±(2%+2) means that a reading of 100.0 V on the multimeter can be from 97.8 V to 102.2 V. Use of a digital multimeter with higher accuracy allows for a great number of applications. Basic dc accuracy of Fluke handheld digital multimeters ranges from 0.5% to 0.025%.
