ST-2551 Insulation Testers
Up To 1 kV (Digital)
|
 |
|
|
FEATURES |
| |
 A LCD indicated instrument for Insulation (M Ohm), Continuity (Ohm) and AC Voltage. |
| Instant operation is possible with a push button. |
| In additon, for continuous measurement of M Ohm or ACV, a convenient timer is provided iwth 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. |
| Auto ranging. |
| Most suitable for insulation resistance measurement of electrical household appliances, power line distribution and installation. |
| CAT II 600V. |
