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 Fluke 1550C performs digital insulation testing up to 5 kV, and makes data collection easy through the Fluke Connect™ wireless app. Remote operation lets you spend as little time as possible in potentially hazardous zones. Real-time trending shows a live graph on your phone, rather than a hard-to-read set of changing values. And you can create reports quickly, using pre-designed templates that you can customize with company logos. It’s the perfect tool for preventive or predictive maintenance programs designed to identify potential equipment failures before they occur. And it comes with a three-year warranty and CAT IV 600 V safety rating.

Now there is one intrinsically safe digital multimeter (DMM) you can use in IIC (gas), in Zones 1 and 2, and IIIC (dust), Zones 21 and 22. Whether you work in an oil, chemical, or pharmaceutical environment , all the test and troubleshooting capabilities you need are in the most robust and intrinsically secure (IS) Fluke DMM ever made. The Fluke 28 II Ex is also water, dust and drop resistant. You will be equipped to solve all problems, inside and outside the danger zone, without compromising on compliance or measurement performance.

From the control room to the factory floor, the Fluke 80 Series digital multimeter has earned a reputation as the digital multimeter that industrial technicians trust. When productivity suffers, the Fluke 80 Series provides the accuracy and advanced troubleshooting capabilities you need to solve problems fast.



Use the low pass filter function to accurately measure voltage and frequency on electrically noisy equipment such as variable speed motor drives. Use the peak capture function to detect occasional faults and switch as fast as 250 microseconds (µs).



And work with confidence. The Input Alert function provides an audio alert against misuse of the input plug. The Fluke 80 Series multimeters have been tested separately for use in CAT IV 600 V/CAT III 1000 V environments. The Series can withstand impulses in excess of 8000 V and reduce the risks associated with surges and surges.



At Fluke, our ideas come straight from the workplace. We work with users like you to build test kits that do the job you want them to do for as long as you need them—and give you full value. We design and manufacture the Fluke 80 Series multimeters in the U.S.A. The 80 Series is backed by a limited lifetime warranty. And we back it with a limited lifetime warranty so you can work smarter, faster, and safer.
