First USEPA Approved Free Chlorine Test Strip

Industrial Test Systems, Inc., is pleased to announce that its SenSafe™Free ChlorineWater Check test strip is available for compliance testing as described in the Federal Register (Vol 72, No. 47, Monday, March 12, 2007, p.11204, ITS Method D99–003). SenSafe™ Free Chlorine Water Check can now be treated as an equivalent to other free chlorine test kits. States will have the discretion to approve their use per authority at 40 CFR 141.74 (a) (2).
Municipalities now have a rapid, (40 seconds), accurate, and low–cost option for regulatory compliance monitoring. As an alternative to DPD, SenSafe™ Free Chlorine Water Check test strips avoid the errors inherent to currently available test methods. The patented design of the strip (US Pat. Nos. 5491094 & 6541269) makes this possible. All of the reagents needed to perform the test are embedded in a "solid state" in the reaction area of the aperture.
Sold in bottles of 50 test strips (part no. 481026) and in 30 individually-wrapped packets with a color chart card (part no. 481126), both with a detection range of 0.0, 0.05, 0.1, 0.2, 0.4, 0.6, 0.8, 1.2, 1.5, 2.0, 4.0, 6.0 mg/l, SenSafe™ Free ChlorineWater check is affordable; with a retail price for either packing option of only $17.99. That's only $0.36 per test (based on a bottle of 50 test strips).
