台湾标准电机SEW仪器仪表--ST-1503 Insulation Testers Up To 1 kV Analog
ST-1503 Insulation Testers Up To 1 kV (Analog)
FEATURES
High quality Tau Band movement.
It is a light and portable combination instrument for testing insulation (M Ohm). continuity (Ohm) and AC voltage.
Instant operation is possible with a pushbutton, in addition, for continuous measurement of M Ohm or Ohm, a convenient timer is provided with automatic power off after three to five minutes to save the battery power.
LED (red) indication when testing insulation and continuity.
Use of a high efficiency and accurate DC-DC converter.
Most suitable for insulation resistance measurement of electrical household appliances, power line distribution and installation.
CAT II 600V.
