The use of chlorine-based biocides is one of the common processes in the field of cooling tower water conditioning.
Monitoring within water treatment processes is carried out, for example, using so-called redox electrodes. It should be noted that the redox value is only an auxiliary parameter that provides information about the reduction or oxidation capacity of the conditioned water. A direct statement about the actual concentration of the reactive component of the supplied product is thus only possible indirectly.
Alternatively, amperometric sensors can be used for specific applications. The disadvantage of this method is the susceptibility to faults or the inertia of the sensor system with regard to fluctuations in the pH value and the temperature, but also in the chlorine concentration. Fluctuations of more than 20% within the chlorine concentration to be measured can already lead to measured values that cannot be used for process engineering purposes.
When integrating the sensor system, stable flow and pressure conditions must also be ensured. Sensor systems require regular calibration and are subject to wear on the electrodes and electrode membranes. Depending on the operating conditions, sensors must be calibrated weekly.
Testomat® LAB Chlor uses the DPD method based on DIN EN ISO 7393-2 to determine the concentration of free chlorine. One advantage of this colorimetric measuring method over the sensory measuring methods is that it is not subject to changes in temperature, pH value or chlorine concentration and therefore works stably even under pressure and flow rate fluctuations.
The determination by means of the DPD method, which is an absolute measuring method, makes it possible to analytically determine the current concentration of the reactive component at any time and thus enables precise monitoring of the current concentration values and thus the associated distortion rate in e.g. cooling tower water.
When processing the measured values in a higher-level control system (output via 4-20 mA or RS232), the required dosing quantities can be realized as needed, independent of seasonal or process-specific fluctuations. Over- or underdosing can thus be effectively counteracted and the use of chemical products can be limited to what is actually required. Long-term observations of the measured values allow reliable conclusions to be drawn about the dosing process without having to take into account any disturbance variables, sensor drift or delayed response behavior. With a measuring range of 0 - 5 mg/l, Testomat® LAB Chlor enables reliable monitoring of both free chlorine and total chlorine in a wide range of applications. The respective parameter is determined by the selection of the reagent set used.

Testomat® EVO TH + LAB CL with NeoTecMaster® - value-added package
Product number:
851065
The Testomat® EVO TH automatically determines the water hardness by means of titration. The device is suitable for controlling the water quality of water treatment plants, drinking water systems, industrial boilers and for monitoring process water. On top of that our Testomat® EVO TH is approved for boiler houses | component identification no.: TÜV. WÜH. 21-025 | VdTÜV bulletin water monitoring device 100 and UL-TÜV certified.
It is supplemented by the Testomat® LAB CL, 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® EVO TH and the Testomat® LAB CL in combination with the NeoTecMaster®, 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 on the NeoTecMaster® , in this case the RS232 interface and one additional RS232 interface on the included NeoTec Slave module , are used by Testomat® EVO TH and 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 flexible manner. A module that fundamentally expands the range of functions and is already included in the scope of delivery is our NeoTec slave relay module with which you can add potential-free relay contacts to the overall system. You can freely assign these to the incoming measurement signals and thus, for example, implement limit value-related control concepts, as well as output measurement-related messages.
Further advantages of the NeoTecMaster:
Simple operation
Integration of the Testomat® world of instruments, here in conjunction with the Testomat® EVO TH and Testomat® LAB CL
Integration into the existing control cabinet, alternatively we offer our NeoTecMaster® housing
Modular range of functions can be extended by NeoTec slave and signal converter modules (measurement, control, regulation)
