GENERAL DESCRIPTIONBecause the system is simple and efficient, water sterilisation by UV irradiation has developed strongly in recent years.The UV-C rays produced are considerably more intense than sunlight and for this reason are used to sterilise water. This technology is recognised in the field of disinfection for the removal of legionella, microbes, bacteria, viruses and protozoa, and this with respect for the environment. It is the ideal process for killing microorganisms in water. It makes water potable from a bacteriological point of view.

The Testomat® 808 is a compact analyser for online measurement of water hardness according to the principle of "limit value monitoring with colour change" in the measuring range 0.02 - 5 ° dH (0.4 - 89 ppm). Applications of the continuous residual hardness monitoring are e.g.: Reverse osmosis systems, boiler feed water supply Soft water for commercial purposes, ultrapure water systems. In view of the fact that the Testomat® 808 is suitable for use in multi-parameter systems due to its 4-20mA signal output, we hereby offer you the Testomat® 808 in conjunction with the NeoTecMaster® Multicontroller, which was specially developed by our company, as a package solution at a preferential price. The 4-channel NeoTecMaster® Multicontroller included in this package enables the processing of up to four measurement signals. Via the 4-20mA NeoTec slave input module connected to the NeoTecMaster®, the data is transmitted to the NeoTecMaster® and used to display the measured value, the trend and the status messages on the 5-inch screen. In addition, the NeoTecMaster® has an RS232 interface as well as 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. This allows the future realisation of further control concepts in a flexible way. Two modules which fundamentally extend the range of functions and are already included in the scope of delivery are our NeoTec slave relay module and the 4x 4-20mA input module. This allows you to add potential-free relay contacts to the overall system and to integrate and visualise further system technology such as sensors via the 4x 4-20mA input module. You can freely assign the relay contacts to the incoming measurement signals and thus, for example, implement simple limit value-related control concepts as well as output measurement value-related messages. Further advantages of the NeoTecMaster: Simple operation Integration of the Testomat® device world, here in connection with the Testomat® 808 Integration into the existing control cabinet, alternatively we offer our NeoTecMaster® enclosure Modular range of functions can be extended by NeoTec slave and signal converter modules (measurement, control, regulation) Available as built-in or surface-mounted variant Structured continuous data recording on the integrated SD card or optionally available SDHC card (2Gbyte) as a file in CSV format In addition, there are the proven functionalities of the Testomat® 808: Indication of limit value undershoot or overshoot: green / red LED Modern indicator pump system Automatic measuring sequence with low water consumption Direct error and indicator quantity display Internal and external flushing of the measuring chamber by manual control Control of an external flush valve Three potential-free relays for: External flush valve control Limit value evaluation External control and / or alarm processingSafety check for 72-hour operation without supervision Indicator quantities: 100 and 500 ml bottles 4 - 20 mA interface for defined status and error messages RS 232 interface for firmware updates General informationWater connection and operating pressure: Depending on unit version: 0.3 - 1 bar / 0.3 x 105 to 4 x 105 Pa 1 - 4 bar / 1 x 105 to 4 x 105 Pa (from 4 to 8 bar, a pressure reducer must be used (special accessory)) Water inlet: opaque hose with 6 mm outer diameter/4 mm inner diameter Water outlet: hose with 6 mm outer diameter/4 mm inner diameter Water temperature: 10 to 40 °CFrom 4 bar, a separately available pressure reducer must be used.
