Product Overview: Fluke 28II Ex native safety true RMS digital multimeter
The Fluke 28 II Ex industrial intrinsic safety digital multimeter has all the measuring functions
Whether you are inside or outside ATEX Zone 1, Zone 2, Zone 21 or zone 22, this tool provides you with all the testing and troubleshooting capabilities you need. No need to carry different instruments for different areas, and no need to worry about carrying non-explosion-proof grade tools through the explosion-proof required areas
4-1/2 digital mode for accurate measurement (20,000 words)
True RMS AC voltage and current can accurately measure nonlinear signals
Ac and DC voltages and currents up to 1000V and 10A can be measured (note that the Ex zone requires reduced measurements)
The low-pass filter ensures accurate measurement of voltage and frequency to the variable speed driver (VSD)
Frequencies up to 200 kHz and duty cycles help you diagnose VSD and switching power supplies
Resistance, connectivity and diode testing
The capacity range of the motor starting capacitor or component is 10,000 μF
High resistance or leakage test conductance measurement
Capture minimum/maximum mean and peak values to automatically record transients and changes
Relative mode to exclude interference from the test wire for resistance measurement
Manual and automatic range selection, flexibility is strong
When the wire is inserted into the wrong input jack, the input alarm will beep and blink. Lead" To protect your safety
Easy to use
Important additional features ensure that you stay productive all day long in poor locations
Even if you're wearing full PPE, backlit keyboard buttons provide good visibility in poorly lit areas
A large digital disy and 2 levels of bright white backlight also add visibility
Long battery life - usually 400 hours without backlight (alkaline battery)
Optional magnetic hooks are easy to set up and easy to read, leaving your hands free for other tasks
Convenient on-site maintenance
The split battery case makes it easy to rece batteries or fuses without compromising the accuracy of the instrument
There is a native safety multimeter (DMM) available for IIC (gas) Zone 1 and 2 and IIIC (dust) zone 21 and 22. Whether you work in a petroleum, chemical or pharmaceutical environment, you get all the testing and troubleshooting capabilities you need with this durable intrinsic Safety (IS) multimeter (DMM) manufactured by Fluke. At the same time, the Fluke 28II Ex/CN is water resistant, dust resistant and fall resistant. With Fluke 28II Ex/CN, you can handle all situations, both in and out of the hazard zone, without violating regulations or sacrificing measurement performance
