The HT Instruments NEPTUNE Multimeter/Insulation Tester is a mix of technology that includes an instrument for electrical safety testing (insulation up to 1000V and continuity with 200mA), an Harmonics analyzer and a True RMS multimeter.
HT Instruments NEPTUNE Key Features:
- it can quickly measure insulation up to 1000V, just like top-of-the-range testers.
- 50,100,250,500,1000VDC Insulation test voltages.
- it measures continuity of protective conductors with 200mA to solve the most common problems related to masses.
- measure Inrush currents, Harmonics and THD%, just like top-of-the-range power quality analyzers.
- with a wide range of external clamp transducers it can measure AC TRMS, DC, AC+DC current and Inrush current, starting from 1mA up to 3000A.
- compare each measurement with the limits prescribed by the Guidelines and I provide a clear result OK or NOT OK
- it’s a multimeter with functions only available if using top-of-the-range instruments.
- CAT IV 600V, CAT III 1000V Safety Rating
- Similar to the Fluke 1587 & Fluke 1577
- ISO 9000 CALIBRATION CERTIFICATE INCLUDED
