ST-2551   Insulation Testers
Up To 1 kV (Digital)  
ST-2551
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.
