Product information "Testomat® LAB CL"
Testomat LAB CL – Online Measuring Transmitter for Total Chlorine and Free Chlorine
Precise chlorine monitoring device from Heyl for water treatment systems
The Testomat LAB CL is a wet-chemical online measuring transmitter for the precise analysis of total chlorine or free chlorine in water.
The Testomat has been developed for use in multi-parameter systems and for connection to higher-level control systems. The analysis is based on the DPD method in accordance with EN ISO 7393-2: two reagents are dosed, and after a reaction time of approximately 60 seconds, the measurement result is available.
Integrated data storage on an SD or SDHC card in CSV format simplifies operation and evaluation. Measurement values, status messages, and error messages can be transmitted to higher-level control systems via the 4–20 mA output and the RS232 interface.
Device features and benefits
The Testomat LAB CL impresses with precise and reliable chlorine analysis based on DPD photometry in a measuring range of 0–5 mg/l. Thanks to its design and flexible interfaces, the device can be easily integrated into existing systems. Automatic data storage, simple operation, and low-maintenance components ensure efficient operation.
Wide range of applications
- Monitoring water quality in water treatment and drinking water facilities
- Process monitoring
- Monitoring chlorine concentration in cooling tower processes
- Connection to higher-level control systems
