The Elcometer 138/2 Surface Contamination Kit provides materials to
collect a sample of contamination from a surface in accordance with

measured using single-use test strips.

3 TEST PROCEDURE

The test procedure consists of two stages:
Stage 1: Produce a solution
Stage 2: Test the solution for chloride, iron or pH as required

3.1 BEFORE YOU START

1 As the test is extremely sensitive, clean latex or nitrile gloves
should be worn during the extraction of soluble salts to prevent
contamination of the surface or sample.
2 Ensure that all parts which come into contact with the test
solution are clean; the beaker, the syringe and the needle. Rinse
with pure water if necessary.
3.2 PRODUCING A SOLUTION
1 Remove the printed protective backing
and foam centre from the Bresle
patch.
