1. MICROPROCESSOR RESIDUAL CHLORINE/OZONE TRANSMITTER

Online - CT-6110-RS Free Chlorine/Ozone Transmitter

The new design of CT-6110-RS can connect the free Cl electrode/ozone electrode/pH electrode to achieve a powerful accurate measurement

Powerful measurement with dual parameters

The CT-6110-RS transmitter has a rugged IP 65 enclosure and can be wall, panel, or pipe mounted in almost all industrial installations. Compatible with residual chlorine electrodes or ozone electrodes, the CT-6110-RS can also connect with pH electrodes for compensation which provides more stable and accurate measurement. In addition to inheriting the graphic menu and easy operation advantages of our intelligent series, the transmitter also contains RS model features including RS485 interface, measurement curve display, and the event logbook function.

Applications:

• Recycle water treatment

• Drinking water disinfection

• Beverage bottle disinfection

• Swimming pool

• Industrial process

• Water treatment

Features:

• Real-time monitoring of pH

• pH compensation for residual chlorine measurements provide accurate measurement and control

• Measured values can be selected for figure or chart display

• Trace mode can display historically measured value curve from 3-minute to 4-week program

• Equipped with events logbook function and password protection

• Easy operation, dual channel, analog and Modbus output transmitter

Calibration Method

• Zero: Pure water or activated charcoal filtered water (residual chlorine/O3 free water) calibration

• Span: 1. Input sampling DPD measurement result for residual chlorine calibration 2. Use a spectrophotometer with ozone reagent to obtain a reference value, then compare with transmitter measurement

• Clean/Auto Zero: Relay contact, ON: 0~99min. 59 sec. / OFF:0~999 hours 59 minutes
