Sulfite drop count test kit where 1 drop equals 2ppm or 10ppm as NA₂SO₃ as a 25mL test. Sulfites are used to remove dissolved oxygen from treatment water. Excess sulfite at elevated temperature combines with oxygen to reduce pitting. Remember to cool your samples quickly and perform the test immediately. Each test kit is packaged in a durable plastic case with instructions and includes all items to complete approximately 60–75 tests.
