Fluke 726 Precision Multifunction Calibrators
Process calibration designed specifically for process industries
The Fluke 726 is a precise and powerful, yet easy-to-use, field calibrator. It features broad workload coverage, calibration power, and unsurpassed accuracy needed by process professionals. It measures and sources almost all process parameters to calibrate almost anything. Use it to test sensors and valves, and to test and calibrate transmitters. The 726 interprets results without the help of a calculator and stores measurement data for later analysis.
Measurement capabilities
This precision multifunction calibrator measures volts, mA, pressure, RTDs, thermocouples, frequency, and resistance to test sensors and transmitters. The 726 also sources and simulates volts, mA, thermocouples, RTDs, frequency to calibrate transmitters. Measures and/or sources pressure using when paired with any of the 50 Fluke 750P series Pressure Modules to test and calibrate pressure transmitters and other devices. The 726 can also:
- Source mA with simultaneous pressure measurement to conduct valve and I/P test
- Conduct enhanced flowmeter testing with frequency totalizer and frequency pulse train source mode
Designed for ease of use
The 726 has built-in features that make it easier to use in nearly any measurement situation. From its ability to store frequently used test setups, to programming custom RTD probe calibration constants for enhanced temperature measurement, or the integrated voltage input protection design that improves reliability, the 726 is built to perform. The use of two separate channels even allows you to measure, source, or view process signals simultaneously. The backlit display provides better visibility in low-light conditions, and the standard 3-year warranty provides extra confidence that the 726 will be there when you need it to be.
You can also use the 726 to:
- Capture the set, reset, and deadband of a pressure switch with the integrated switch test
- Calculate the transmitter error % to interpret calibration results without the use of a calculator
- Perform fast linearity tests with the auto-step and auto-ramp features
- Power a transmitter during test using 24 V loop supply and simultaneous mA measurement

The P3100 models are available in single or dual piston format. Unit can be supplied in psi, bar, kgf/cm², and MPa. This robust instrument is highly accurate, quick and easy to use. Units feature a built-in priming pump for large volume applications, piston flotation indicators and a high quality screw press for fine pressure control.
Operating principle
Deadweight testers are the high performance pressure standards for pressure measurement. Utilizing the well proven piston-gauge system consisting of a vertically mounted, precision lapped piston and cylinder assembly, accurately calibrated weight masses (Force) are loaded on the piston (Area), which rises freely within its cylinder. These weights balance the upward force created by the pressure within the system. The pressure is measured when placed on a correctly spinning and floating piston. The total pressure measured is the summation of the weights plus the piston weight carrier assembly.
Instrument base
There are three basic variations in the hydraulic offering; single low pressure, single high pressure and dual piston models. Pressure is generated and controlled by means of a high quality screw press located on the front of the tester. A built-in hand pump is included as standard for all hydraulic models to prime the system and accommodate large volume requirements.
Piston/cylinder assemblies
The piston/cylinder assembly is the heart of each deadweight tester. They are manufactured from materials that provide stability, durability, and low thermal coefficients and distortion. Our experience and knowledge of piston/cylinder production and calibration ensure the precision and performance required for today’s demanding calibration requirements.
Weight masses
Standard weight masses are series 3 nonmagnetic austenitic stainless steel. Each mass is marked with the serial number of the instrument and the nominal pressure value relative to the high or low-pressure piston, when applicable. Optional fractional weights are stainless steel and/or solution heat treated aluminum.
Gravity correction
Gravity varies significantly with geographical location and this variation has a direct effect on the force of the weights and the accuracy of the deadweight tester. Each instrument can be calibrated to local gravity at no extra cost. If unspecified, instruments will be calibrated to Standard Gravity at 980.665 cm/s2.
Key features
• Pressure ranges to 60,000 psi (4000 bar)
• 0.015% of reading accuracy standard (0.008% optional)
• Single or dual piston format
• Built-in hand pumps standard
• Mounted spirit level with adjustable feet
• Units can be trimmed to local gravity FOC
