A process calibrator is a very versatile instrument. It is equipped with features that allow you to read and source voltage, frequency, current, and resistance signals. This makes it really helpful in performing different types of calibrations in a variety of industrial applications.
The Fluke process calibrators are easy to use and are powerful too. If you’re looking forward to buy a Fluke process calibrator, this guide will help you as we have done a comparison of Fluke 725 vs 726. The Fluke 725 and 726 are reliable and rugged and they are one of the best multifunction process calibrators available on the market. However, since you have to choose one, we have done a comparison between these devices which is as follows.
Fluke 725 review
The fluke 725 multifunction process calibrator allows you to test and calibrate different types of process parameters. You can use the device right away, it has simple and easy to use controls with menus. The backlit display makes it easier to read in low light conditions. The device has a compact and streamline shape- the rugged design makes it good for standing against rigorous usage.
The Fluke 725 can measure and source volts, mA, frequency, loop parameters, temperature (RTDs and thermocouples), pressure, and ohm optional pressure modules. It can also measure a variety of fast pulsed RTD transmitters and PLCs with short pulses of around 10 ms too. Using the device you can source or measure pressure using any of the 29 Fluke 700Pxx Pressure Modules. You can also source mA with simultaneous pressure measurement for conducting I/P and valve tests.
Using the Fluke 725 you can also perform linearity tests with the auto-ramp and auto-step features. If you’re doing flow meter testing you can support it with frequency and CPM functions. The device also has a built-in 24 V loop power supply. If there are some calibration set ups that you use frequently, you can store them and recall whenever needed. The split display of Fluke 725 allows you to view input and output simultaneously. It has a frequency range from 2.0 to 1000.0 CPM and a sensitivity range of 1V peak to peak minimum.
Fluke 726 review
The Fluke 726 is a precision multifunction process calibrator which can measure and calibrate source performance up to 0.01 accuracy. This process calibrator is designed for industrial usage especially if accuracy and superb calibration power is needed. The device has broad workload coverage and it measures all the process parameters so that you can easily calibrate different parameters in your field.
Just like Fluke 725, the 726 is also equipped with a backlit display that allows you to view in dark. You can measure the readings from the display in the form of volts, mA, resistance, RTDs, and thermocouples to test the transmitters and sensors both. You can store the valid results to view them later.
The device features advanced specifications such as the frequency pulse train source mode and frequency totalizer for flowmeter testing. There is a voltage input protection design which is there to improve the reliability of the overall device. Unlike Fluke 725, this device comes with two separate channels that make it easier to source, measure, and view the process signals.
The Fluke 726 can store up to 8 calibration results which you can easily view for analyzing purposes later. The power transmitters are equipped with 24 V loop supply for testing and also allow you to simultaneously measure the mA. The Fluke 726 is also equipped with auto step and auto ramp features just like the Fluke 725.
We did a detailed comparison of the Fluke 725 vs 726 in order to recommend one device out of these. Both the devices have similar features and the differences are slight. Both have split screens for simultaneous readings and they can measure, source, and simulate various process parameters very efficiently.
However, since we have to choose one, our recommendation is the Fluke 726 because it is more accurate as compared to the Fluke 725. It is also contains more handy features like the frequency totalizer, frequency pulse train mode, and two separate channels for measuring, sourcing, and viewing the process signals simultaneously. The Fluke 725 on the other hand is a good choice if you want a more affordable option.
