FLUKE-28IIEX/ETL產(chǎn)品概述
The 28II Ex: the most rugged intrinsically safe digital multimeter in the world.
Now there is one intrinsically safe digital multimeter (DMM) you can use in IIC (gas) Zone 1 and 2 and IIIC (dust) Zone 21 and 22 areas. No need to carry different meters for different areas, or worry about crossing through an Ex-required zone with a non-Ex rated instrument. Whether you work in petroleum, chemical, or pharmaceutical environments, all the test and troubleshooting power you need is packed into the most rugged intrinsically safe (IS) DMM Fluke has ever built. The Fluke 28II Ex is also water-proof, dust-proof and drop-proof. You will be equipped to handle any situation, inside and outside of hazardous zones, without compromising compliance or measurement performance.
Features:
41⁄2 digit mode for precise measurements (20,000 counts)
True-rms ac voltage and current for accurate measurement on nonlinear signals
Measures up to 1000 V and 10 A ac and dc (note that Ex zones require reduced measurements)
Low pass filter ensures accurate voltage and frequency measurements on variable speed motor drives (VSDs)
Frequency to 200 kHz and % duty cycle to help you diagnose VSDs and switching power supplies
Resistance, continuity and diode test
10,000 μF capacitance range for components and motor caps
Conductance measurements for high resistance or leakage tests
Min/Max/Avg and Peak capture to record transients and variations automatically
Relative mode to remove test lead interference on resistance measurements
Auto and manual ranging for maximum flexibility
Input Alert protects you by chirping and flashing "Lead" when leads are plugged into the wrong inputs
