Sefram MW9090, MW9091 Insulation Testers and TRMS-Multimeters
The Sefram MW9090 and MW9091 are handheld insulation testers and multimeters. The devices offer a test voltage of 50, 100, 250, 500, or 1000 V. The range for voltage measurement is either up to 600 V AC TRMS or DC (MW9090), or 1000 V AC TRMS or DC (MW9091). Both versions have a backlit LCD.
- Test voltage: 50 V, 100 V, 250 V, 500 V, 1000 V.
- Insulation resistance up to 20 or 22 GΩ.
- Measurement of polarisation index (PI) and dielectric absorption ratio (DAR).
- Measurement of TRMS AC voltages up to 600 or 1000 V and DC up to 600 or 1000 V.
- Additional in MW9091:
- Current measurement AC and DC (400 mA)
- Resistance measurement, continuity and diode test.
- Frequency measurement.
- Capacitance measurement.
- Temperature measurement.
- Memory: 5x 100 memories.
- Compact, robust and shockproof housing, with protective holster.
- LCD display with backlight.
- Safety: 600 V CAT IV, MW9091 also 1000 V CAT III.
