Fluke 718 -850 mbar to 20 bar Pressure Calibrator

This pressure calibrator provides a compact, portable solution for pressure source generation and milliamp measurement to support calibration and maintenance of transmitters, gauges and switches in industrial settings. It combines a user-facing LCD for simultaneous pressure and current readouts with a protected pneumatic pump design that can be cleaned and serviced in the field, making it suitable for on-site calibration tasks across automation and electrical disciplines.

• ±0.025% accuracy improves measurement confidence for calibration tasks
• 1 mbar resolution allows fine pressure discrimination during tests
• Maximum measurement 20 bar supports higher-pressure device verification
• Minimum measurement −850 mbar enables vacuum and low-pressure checks
• Battery powered with 20 h life reduces interruptions on site
• Current loop measurement capability simplifies transmitter loop diagnostics

• Suitable for calibrating industrial pressure transmitters and transmitters’ loops
• Ideal for pressure switch testing in control panels and process skids
• Used with gauges for field verification and routine maintenance
• Can be used for commissioning and troubleshooting pneumatic control systems
• Suitable for low-pressure and vacuum system checks in laboratory setups

It runs from alkaline batteries and provides typical runtime up to 20 h depending on functions used.

The pump includes protective check valves and a serviceable valve assembly that can be cleaned in situ using isopropyl alcohol and simple tools.

The LCD shows a five-digit pressure Value together with current measurement for concurrent pressure and loop diagnostics.

The operating temperature range is −10°C to 55°C with defined humidity tolerances that reduce at higher temperatures.

The unit weighs 992 g, providing a Compact and lightweight instrument for routine field work.
