        ST-2550   Insulation Testers
        Up To 1 kV (Digital)  
        ST-2550
        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.
