Chlorine tester

The Chlorosense chlorine tester is simpler and less technique-dependent than DPD tablets. It provides quick, simple and accurate testing of a wide range of chlorine concentration levels.

The test is performed with a portable unit, single-use disposable sensors and a small sample of the water to be tested. The electrochemical sensor measures both the total and free chlorine levels simultaneously, and records the results (along with the temperature of the sample) in under a minute.

No use of reagents or careful measuring is required, and the sensitivity and resolution of the test is claimed to be equivalent to DPD testing at low concentrations. Linear measurements means that results are given in the 5-10 mg/L range.

The sensors are provided separately; each box of electrodes being supplied with a calibration chip that must be inserted into the Chlorosense before use. The unit is self-contained, and can store sensors for up to 30 tests to make the procedure as easy as possible. The device can store data from up to 500 individual results, ready to be downloaded via USB to a PC for viewing with any spreadsheet program. It is also rated IP67 (waterproof for 30 mins, 1 m underwater), combining functionality with aesthetic and ergonomic design.

With no reagents needed, the sample container only needs to be washed and refilled and the sensors replaced for a new test to be performed. Chlorosense is designed to complement the existing range of DPD testing techniques.
