Page 4: General Information
The chlorine sensor from the eCHEM sensors product range is an electrochemical sensor for measuring the chlorine concent- ration in water. This sensor detects free chlorine from inorganic chlorine products (chlorine gas, hypochlorite, etc.). The measu- ring method has a reduced pH dependency, so that pH fluctuations only have a limited impact on the measurement signal. pH value increases only lead to an approximately 10% reduction of the measuring signal per pH unit. -
Page 5: Health And Safety Information
Devices that radiate strong electromagnetic waves can influence the measurement data or result in a malfunction of the sen- sor. Avoid using the following devices in the same room as the TriOS sensor: mobile phones, cordless phones, transmitters/ receivers and other electrical devices that produce electromagnetic waves. -
Page 6: Warnings
Stop operation of the sensor in the event of excessive heat development (i.e. if it is hot to the touch). Switch off the sensor immediately and unplug the cable from the power supply. Please contact your dealer or the TriOS customer service. -
Page 7: Intended Use
Other uses do not comply with the intended use. This device has been developed for use in research and industry. It may only be used for the measurement of free chlorine in aqueous fluids such as drinking water, swimming pool water or sea water. The use of other media can damage the sensor. For the use of the chlorine sensor in other media than those specified in this manual, please contact the customer service of TriOS Mess- und Datentechnik GmbH (support@trios. -

This electrical signal is proportional to the chlorine concentration and is amplified by the sensor electronics. Due to an integrated temperature compensati- on, the measuring signal is independent of the temperature of the sample water. D01-905en201912 Manual eCHEM Free Chlorine... -

8. Power (9...30 VDC) Insert the connector into one of the supplied TriOS cables (2 m). Additional cable lengths of 0.3 m, 2 m, 5 m, 10 m, 25 m are offered. Connect the male end of the cable into the connector on the sensor by making the pins align with the slots of the cable. -
Page 13: Interfaces
The sensor must be used for measurements in the flow cell type FLC (see chapter 4). The use of the sensor in other flow cells must be approved by TriOS GmbH. Otherwise, no warranty will be given for the proper functioning of the sensor or for resulting damage to property or personal injury. -
Page 14: Use
Free Chlorine 4 Use The chlorine sensor can be operated with all TriOS controllers. Instructions for correct installation can be found in the relevant controller manual. A bypass installation of the sensor is essential for correct results. Therefore we strongly recommend to use the sensor in the flow cell type FLC for permanent use. - Page 15 Free Chlorine Approx. 122 80.00 18.00 44.00 Screw connection 1 1/4” 6/8 mm hose Sampling Flow control 6/8 mm hose Dimensions in mm D01-905en201912 Manual eCHEM Free Chlorine...

Page 19: Measurement Properties
Gas bubbles in front of the membrane prevent the free chlorine from entering the electrolyte, which falsifies the measuring signal. -

(see figure right). Take a new membrane cap and fill it with electrolyte bubble-free (see section 3.1). If the sensor then still indicates too low or unstable values, it must be checked by the manufacturer.

The formation of a small meniscus can be tolerated since the membrane is hydrophilic. -> Check whether the reference electrode has been damaged by the exchange between measuring medium and electrolyte. If it is no longer in perfect condition, send in the sensor for inspection.
