        1.     
           
          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.
