220V Chlorine Tester OTA Technology For Aquarium 144 * 144 * 120mm

Brief Introduction

The chlorine tester is applied to online monitoring of residual chlorine concentration in drinking water and industrial process water disinfection and sterilization process, sewage treatment and circulating cooling water treatment, and can also be used in swimming pools and other places where residual chlorine concentration needs to be measured.

The ADS2-U4A-CL4.2 online chlorine tester is a single-parameter instrument, each instrument is connected to chlorine sensors to realize the measurement of chlorine. The instrument configures OTA download technology (Over-the-Air Technology) as a smart configuration option.

Advantages Of The Chlorine Tester

1. The protection grade of the chlorine meter’s shell is IP66, which can effectively isolate the pollution and corrosive gas intrusion from the external environment.

2. The large-size display screen of the instrument displays sensor measurement data and other data. The user can use the operation panel on the front of the controller to calibrate the sensor and set various parameters that need to be output.

3. The communication is equipped with a two-wire RS485 interface, the communication protocol is MODBUS RTU. The instrument supports JSON text data format.

4. The chlorine analyzer can record the user's maintenance details of the equipment, the calibration effect of the diagnostic sensor, and will give corresponding prompts for inaccurate calibration instruments.

5. The display uses a 128*64 large LCD screen, and the display backlight provides always on and energy-saving mode selection.
