PTC 313DS Dual Scale Thermometer -20°C to 250°C and 0°F to 500°F - High Precision Temperature Gauge for Cooking, HVAC, Labs & Industrial Use

Product Description

This instrument is thermodynamically designed to measure surface temperatures. It has been calibrated for use in an ambient temperature of approximately 70°F (21°C). For accurate measurements, the thermometer should be used in still air. The surface to be measured should be flat and smooth as more intimate contact will provide more accurate readings. The greater the thermal mass of the source, the more accurate the readings.
