Testomat MODUL CL – Heyl Analysis Technologies

Testomat® MODUL CL

The Testomat® MODUL CL is a robust, wet-chemical online transmitter that measures the content of total chlorine or free chlorine. The device is suitable for water quality control in the environment of water treatment & drinking water plants, process monitoring as well as for monitoring the chlorine concentration in the cooling tower process. The measuring range is 0 to 5 ppm (resolution 0.1).

The instrument operates according to the DPD method based on EN ISO 7393-2. The analysis is performed by adding two reagents. After a reaction time of approx. 60 seconds (dosing and measuring time without rinsing time) the measuring result is available.

Please note that the Testomat® MODUL – CL was developed for use in multi-parameter concepts or for connection to an existing higher-level control concept.

In addition to the 4-20 mA output for transmitting the measured values, this series has an RS232 interface for transmitting the measured values and error & status messages. Furthermore, all data are continuously recorded on the integrated SD card or optionally available SDHC card (2 Gbyte) as a file in CSV format structured and can be used at any time for detailed observations.

The Testomat® MODUL TH convinces with new functionalities:

• RS232 interface for transmission of measured
values and error messages
• Carrying out the parameterization by means
of SD card or the software
• “Service monitor“ via mini-USB (device side)
to USB 2.0 (for example PC/notebook)
• Multilingual menu navigation of the software
in German, English, French, Dutch
• Firmware update via SD card
• Compact design
• Optimized water detection based on an optical
measuring method
• Integrated self-test with continuous monitoring
• Optimized reagent set for the measurement
of total chlorine (reduction from three to two
reagents

Proven performance profile:

• High precision peristaltic roller pumps
• Reliable and low-maintenance operation
• Minimal reagent and water consumption
• Analog output 4 – 20 mA for transmission
of the measured values
• RS232 interface for transmission of measured
values & fault messages
• Common alarm output
• Optimized reagents:
– only 2 reagents for the determination
of total chlorine
• Optimized reagent containers:
– Filling quantities are coordinated so that both
containers are used up at the same time

Analysis resolution:

• Automatic interval operation (interval pause
adjustable from 10-60 minutes)
• Measurement phase operation (start pulse
triggers a sequence of analyses for a period
of 10 minutes to 12 hours)
• External analysis input (start/stop)
• Manual start
