Fluke Fluke-712B Temperature Calibrator, UKAS

This temperature calibrator is a Compact handheld instrument designed for precise temperature measurement and simulation in industrial and laboratory settings. Battery powered for field use, it supports RTD and thermocouple functions and allows simultaneous 4–20mA measurement while sourcing a temperature signal, making it suitable for calibration, troubleshooting and loop testing where traceable, UKAS-calibrated performance is required.

• 0.010% accuracy Plus 2μA to reduce calibration uncertainty
• 0.1°C resolution for fine temperature discrimination
• Supports RTD simulation across multiple sensor types for versatility
• Measures and sources 4–20mA while sourcing temperature for loop checks
• Mini thermocouple plug accepts types from −250°C to 2500°C for wide range
• IEC 61010-1 approval and UKAS traceable calibration certificate for compliance

• Suitable for commissioning temperature transmitters in process control
• Ideal for on-site RTD sensor verification and adjustment
• Used with PLC inputs to validate pulsed transmitters down to 5ms
• Can be used for maintenance of thermocouple-based furnaces and ovens
• Used for field calibration of 4–20mA control loops in automation systems

It runs from four AA batteries providing portable, battery-powered operation for extended site work.

The unit measures and simulates a wide selection of RTD elements and resistance ranges, offering current excitation tailored to each range to provide accurate source and measure modes.

It operates between −10°C and 50°C, supports altitudes up to 2000m, and meets IP52 for protection against limited dust and dripping water.

Yes, it supports Pulsed transmitters and PLCs with Pulse widths as short as 5ms for validation of Rapid signals.

The instrument is lightweight at 515g, includes a magnetic hanging tool for hands-free positioning, and features a backlit display with dual inputs for clear readings.
