The Turtle Tough TT-ISE-CL2 amperometric reagentless chlorine residual analyzer provides continuous free chlorine residual measurement without moving parts in a variety of applications that have clean filtered water of drinking or swimming pool quality.

Reagentless, bufferless operation & no zero-point calibration reduces the cost of operation and maintenance.

The 3-electrode membrane covered potentiostatic chlorine sensor for 4-9 pH is less affected by pH than other sensors. Customers monitoring up to 8.5pH report accurate comparison to lab and grab sample results without the additional expense of a pH sensor for compensation.

The 4.3” full color glass LCD touch screen interface is rated for a minimum of one million touches on one point and simplifies calibration and configuration.

It displays residual in mg/L (PPM), high / low chlorine alarm indication, optional flow status or alarm, and processor status.

Designed for 24/7 operation, the system can also be used at well sites or booster stations that only operate several hours each day since the sensor can tolerate zero chlorine water for up to 24 hours. A settling time of up to 1-2 hours is required upon re-start. With no reagent addition, sample can be recycled back into the process if permitted.

The feature packed electronics platform provides expansion capability that can grow with your needs. Options such as eight (8) sensor inputs, PID/compound loop control or enhanced communications can be added without replacing the original instrument when these options are available.
