Product Overview

The Fluke 51 II is a single-input digital contact thermometer in the Fluke 50 Series II, designed for temperature measurements in industrial maintenance, HVAC, laboratory and process applications. It supports J, K, T and E-type thermocouples, with a K-type instrument measurement range of −200°C to +1372°C and a basic temperature accuracy of ±(0.05% + 0.3°C) above −100°C. Its backlit dual-line LCD supports temperature readings in Celsius, Fahrenheit and Kelvin. The instrument features MIN/MAX/AVG recording, relative time reference and electronic offset adjustment for thermocouple compensation. The portable unit operates on three AA batteries, providing a typical battery life of approximately 1000 hours. The supplied actual product photographs show a thermometer marked Fluke 51 II and an orange thermocouple lead, together with Fluke 51/52 II series packaging. The full accessory set, operational condition and calibration status should be confirmed before ordering.
