ST-2550 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. |
