Fluke 51 II Handheld Digital Probe Thermometer

Fluke 51 II Handheld Digital Probe Thermometer

In a short time, hand-held infrared (IR) thermometers have gone from exotic to commonplace. Portable and convenient, they are useful for troubleshooting and checking both product quality and process quality. Fluke’s family of IR thermometers offers users speed and convenience.

Applications for infrared thermometers

Infrared thermometry can be used for process monitoring, plant predictive and preventive maintenance, electrical applications, quality assurance, and other applications.

Infrared (IR) non-contact thermometers are ideal for moving targets and machinery, hazardous and inaccessible or distant targets, electrical components, “big picture” evaluations of machinery or surfaces, trending records, and even protection against litigation and insurance claims. In fact, insurance companies are encouraging their customers to implement preventive infrared scanning.

IR thermometers and imagers can save time and money for contractor and customer alike, as well as perform diagnostics that were previously impossible without shutting down systems.

The Fluke Model 51  Thermometer (“the thermometer”) are microprocessor-based, digital thermometers designed to use external J-, K-, T-, and E type thermocouples (temperature probes) as temperature sensors. Use the thermometer only as specified in this manual. Otherwise, the protection provided by the meter may be impaired.

The Fluke 51 II single input digital thermometer delivers fast response with laboratory accuracy (0.05% + 0.3°C). You can use the 51 II to measure contact temperature on motors, insulation, breakers, pipes, corroded connections, liquids, and wires with industrial standard J, K, T, or E-type thermocouple temperature sensors. The user friendly-front panel and large, backlit display make it easy to view results. And the sleep mode feature preserves battery life to give you a typical thousand hours of operation.

Other useful features:

• Easy-to-access battery door that allows replacing the battery without breaking the calibration seal
• Comes with splash- and dust-resistant case protected by an impact-absorbing holster and a three-year warranty
• Powered by three, standard AA batteries -30-
• Includes an electronic offset function that compensates for thermocouple errors to maximize overall accuracy
• Handles temperatures up to 900°C (1600°F)
• Provides a user-friendly front panel that is easy to set up and operate
• Offers sleep mode to increase battery life; 1000-hour battery life typical
• Offers optional ToolPak accessory to hang the thermometer from any metal object (with the rare earth magnet) or secure around a pipe (with hook-and-loop straps) for hands-free operation
