Fluke Digital Thermometer, 1372°C Maximum Temperature Measurement, ±0.3K Accuracy - FLUKE-51-2

This digital thermometer is a handheld, battery-powered instrument designed for precise temperature measurement across industrial settings. It accepts wired thermocouple probes and displays readings on a digital screen, serving users in automation, electronics, electrical and mechanical fields who require portable, accurate temperature monitoring without mains power.

Features & Benefits

• ±0.3K Basic accuracy provides precise measurement confidence
• Measures up to 1372°C for high-temperature applications
• Accepts Type K, J, T and E probes for broad thermocouple compatibility
• 3xAA battery power delivers approximately 1000 h of operation
• Records min/max and averages to capture transient events
• Weight 400 g enables easy handheld portability on site

Applications

• Suitable for checking component temperatures in electronics assembly
• Ideal for maintenance of mechanical bearings and heated tooling
• Used for field verification of temperature sensors and probes
• Can be used for process checks in electrical cabinet diagnostics
• Used with K-type bead probes for HVAC commissioning tasks

What probe types can I connect for different materials?

The instrument supports Type K, J, T and E thermocouples, allowing selection based on temperature range and material contact characteristics for accurate sensing.

How does the display resolution affect small-change readings?

Resolution is 0.1°C/°F/K below 1000° and 1.0° at or above 1000°, enabling fine resolution for most industrial measurements and coarser steps at extreme temperatures.

What environmental range can it tolerate during transport and storage?

It can be stored between −40°C and +60°C and operated from −10°C to +50°C, with defined humidity limits across the operating band.

Are there options for logging or PC Interface on this model?

This particular unit provides single-input wired measurement and min/max recording

models with logging and PC connectivity are specified in the wider product family.

What safety or installation limits should be observed for measurements?

Do not apply voltages exceeding 30 Vac rms, 42 Vpk, or 60V dc referenced to earth, and ensure common-mode differences between inputs remain within 1V for differential accuracy.
