Fluke Digital Thermometer, 160°C Maximum Temperature Measurement, ±0.05°C Accuracy - 1551A-20

This digital thermometer is a handheld instrument designed for precise temperature measurement in industrial settings. It accepts a single RTD probe input and displays readings in °C or °F with very fine resolution. The device is battery powered and incorporates intrinsic safety features for hazardous locations, enabling use where explosive atmospheres are present.

Features and Benefits:

• Accuracy ±0.05°C for high-precision monitoring
• Resolution 0.001°C for detecting minute temperature changes
• Maximum measurement 160°C for elevated-temperature tasks
• Data storage capability for logged measurement review
• Battery life 300h for extended field operations
• Powered by AAA batteries for convenient replacement

Applications

• Suitable for process control in chemical plants
• Used for maintenance in hazardous-area zones
• Ideal for calibration of industrial sensors
• Can be used for temperature verification in manufacturing
• Used with RTD probes for laboratory-grade checks

How is the instrument certified for use in explosive atmospheres?

It meets ATEX requirements and is designed to comply with IEC 60079-0 and IEC 60079-11 standards to allow deployment in classified hazardous areas.

What input type is required for temperature sensing?

It uses an RTD probe input, providing stable resistance-based temperature measurement suitable for industrial transducers.

How compact and portable is the unit for site inspections?

The handheld form factor weighs 196 g and is sized for easy handling and transport during on-site diagnostics.

Can it record and retain measurement history during shifts?

Yes, it includes onboard data storage to capture and retain readings for later review or transfer.
