Most specifications do not address sulfates or nitrates because there has never been a sulfate or nitrate field test kit.
Now there is a complete test kit available that tests all three salts. CHLOR*TEST "CSN Salts" offers the specifier the availability of trouble-free performance testings, in the field, for chlorides, sulfates, and nitrates with one extraction. The CHLOR*TEST "CSN Salts" uses a unique patented extract solution, CHLOR*EXTRACTº, to retrieve surface salt contamination. This special extract enhances retrieval rates, thereby increasing accuracy. The greater the retrieval rate, the more accurate the test results. Surface sampling is simplified by use of the patented CHLOR*SLEEVE® . Sampling can be done overhead, vertically, horizontally or any angle with this device.
