Fluke FLK-729 30G -0.82 bar to 2.06 bar Pressure Calibrator, RSCAL

This pressure calibrator is a portable automatic instrument designed for process technicians to generate, control and measure pressure while also sourcing and simulating mA signals in field environments. It simplifies multi-point pressure verification by automatically pumping to user-defined set-points and recording applied pressure and loop current, enabling efficient on-site calibration and diagnosis across industrial automation and instrumentation tasks.

• Automatic pressure pumping to user-entered set-points for fast calibration
• Control accuracy down to 0.005% full-scale for precise regulation
• Measures and sources 0–24 mA with 24V loop power for loop testing
• Built-in leak test to verify integrity of hoses and fittings
• Onboard data logging and template documentation for test records
• Rechargeable battery operation for field portability and off-grid use

• Suitable for commissioning and calibrating process transmitters on site
• Ideal for HART transmitter trim and zero adjustments during maintenance
• Used for automated multi-point calibration of pressure switches
• Can be used with an RTD probe to verify temperature-dependent instruments
• Suitable for portable verification of control-valve positioners and I/Ps

This variant measures from −0.82737 to 2.06842 bar with fine resolution suitable for low-pressure process loops.

It logs measured and sourced values to onboard storage and supports wireless upload for compatible systems when wirelessly equipped.

Pressure control is rated to operate between 0°C and 50°C while measurement functions operate from −10°C to 50°C, with battery charging restricted above 40°C.

The unit weighs 2.95 kg, has an IP54 ingress rating and includes a semi-rigid carrying case with storage for hoses and accessories.

It accepts legacy pressure modules for alternate ranges and supports an optional 720RTD probe for temperature measurements.
