Fluke 51 II Handheld Digital Thermometer
Short Description:
Fluke 51 II Handheld Digital Thermometer key features:
- Single Input digital thermometer for lab, QA, process calibration, food safety, and HVAC
- Measures J, K, T, and E-type thermocouples
- Presents results in °C, °F, or Kelvin (K) on a large backlit display
- Includes a relative time clock on MIN, MAX, and AVG to provide a time reference for major events
Fluke 51 ii handheld digital probe thermometer
The Fluke 51 II unmarried enter virtual thermometer supplies speedy reaction with laboratory accuracy (0.05% + 0.3°C). You can use the 51 -2 degree contact temperature on motors, insulation, breakers, pipes, corroded connections, liquids, and wires with commercial well-known J, K, T, or E-kind thermocouple temperature sensors.
The person-friendly friendly-the front panel and large, backlit show make it clean to view results. The sleep mode function preserves battery existence to provide you with a normal thousand hours of operation.
Other beneficial features of Fluke 51 II:
- Easy-to-get entry to battery door that permits changing the battery without breaking the calibration seal
- Comes with splash- and dust-resistant case included via way of means of an impact-absorbing -holster and a three-yr warranty
- Powered via way of means of three, widespread AA batteries -30-
- Includes a digital offset characteristic that compensates for thermocouple mistakes to maximize ordinary accuracy
- Handles temperatures as much as 900°C (1600°F)
- Provides a user-pleasant front panel that is simple to install and operate
- Offers sleep mode to growth battery lifestyles; 1000-hour battery lifestyles typical
- Offers optionally available ToolPak accent to dangle the thermometer from any metallic object — (with the uncommon earth magnet) or steady round a pipe (with hook-and-loop straps) for hands-loose operation
Fluke 51 II safety information: warning and precautions
A Warning identifies situations and movements that pose hazards to the user. To keep away from electric surprise or personal injury, follow these guidelines:
• Before the usage of the thermometer investigate the case. Do now no longer use the thermometer if it seems damaged. Look for cracks or lacking plastic. Pay precise interest to the insulation across the connectors.
• Disconnect the thermocouple(s) from the thermometer earlier than starting the case.
• Replace the batteries as quickly because the battery indicator () seems. The opportunity of fake readings can lead to private injury.
• Do now no longer use the thermometer if it operates abnormally. Protection can be impaired. When in doubt, have the thermometer serviced.
• Do now no longer function the thermometer around explosive gas, vapor, or dust.
• Reflective gadgets bring about a decrease in real temperature measurements. These gadgets pose a burn hazard.
• Do now no longer connect with voltages >30 V ac rms, forty-two V pk, 60 V dc from earth ground
Models fifty-two and 54: Measurement mistakes may also arise if voltages at the size surfaces bring about potentials extra than 1 V among the 2 thermocouples. When potential variations are expected among the thermocouples, use electrically insulated thermocouples.
• When servicing the thermometer, use the handiest specified alternative parts.
• Do now no longer use the thermometer with any part of the case or cowl removed

Fluke Thermometer 51 ii Performance Tests
Performance checks are encouraged for incoming inspection, periodic maintenance, and for checking the thermometer’s specifications. If the thermometer fails any part of the overall performance checks, calibration, and/or restoration is indicated.
Before appearing those checks:
1. Allow the thermometer to stabilize to room temperature, +23 o C ± five o C (+seventy-three oF ± nine oF).
2. Check the batteries and update them if necessary
Fluke 51 II Ice Bath Construction
To start the overall performance check, first, assemble an ice bath as follows:
1. Prepare a Dewar Flask by drilling holes in its cap to just accept the Mercury thermometer and thermocouple wires, or use a fashionable laboratory cork.
2. Fill the Dewar Flask with shaved or beaten ice crafted from distilled water. 3. Fill the Dewar Flask with sufficient distilled water in order that the ice turns to slush, however, do now no longer upload sufficient water to glide the ice.
