Testomat® LAB CL with NeoTecMaster® - value-added package
Product number: 851067
The Testomat® LAB CL is a robust wet chemical online measuring converter to measure the concentration of total chlorine or free chlorine in the measuring range 0 - 5 mg/l. The instrument is suitable for controlling the water quality of water treatment plants, drinking water plants, process water monitoring and for monitoring the chlorine concentration in the cooling tower process. Instrument operation is based on the DPD method according to EN ISO 7393-2. The analysis is carried out through the addition of two reagents and the measurement result is obtained after a reaction time of approx. 60 seconds (pure measurement time without flush time).

In view of the fact that the Testomat® LAB CL was developed for use in multi-parameter systems or for connection to a higher-level control system, we hereby offer you the Testomat® LAB CL in combination with the NeoTecMaster® Multi Channel Controller, which was specially developed by our company, as a package solution at a preferential price. 

The 4-channel NeoTecMaster® multi-parameter controller included in this package enables the processing of up to four measurement signals in this version. A signal input, in this case the RS232 interface, is used by the Testomat® LAB CL to display the measured value, the trend and the status messages on the 5 inch screen. 

In addition to the on board RS232 interface, the NeoTecMaster® also has a Modbus RTU input, which you can use freely after brief technical consultation with us. (Pre-check whether your existing measurement technology to be integrated requires adjustments). 

The NeoTecMaster® can be systematically supplemented with further optional NeoTec modules (function / signal converter modules) as required, thus enabling the future realisation of further control concepts in a flexib ...
