GTM 1300




The instrument measure the electrical resistance of concrete against the penetration of chloride according
to ASTM C1202 standard , based on the charge passing through the samples by applying 30 or 60Vdc on
both ends of concrete sample.


    • Measure up to 4 samples with separate selectable operation( 6 channels is available upon request)
    • Indication for Applied Volt and measures current.
    • Protection against short circuit.
    • Ending the test if very high chloride penetration is detected.
    • User Friendly PC software ( Dragon 1300 ).
    • Rugged design.
    • USB connection to PC/Laptop , no special interface required.
    • Fine adjustment for applied DC volt.
    • Indication for short circuit.
