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. |
