Testomat 808 Limit value measuring devices for monitoring water hardness, residual hardness and silicate 

The Testomat® 808 is a compact analyzer for the online measurement of water hardness according to the principle of " limit value monitoring by color change ". The Testomat® style="letter-spacing: 0px;"> 808 is a combination of the latest technologies based upon decades of international Testomat® experience.Applications of continuous residual hardness monitoring are for example: Reverse osmosis plants Boiler feed water supply Soft water for commercial puposes Pure water systems Performance profile:Limit value indication (not exceeded or exceeded: green / red LED) Modern indicator pump system Automatic measuring process with low water consumption Direct error and indicator quantity indication Internal and external flushing of the measuring chamber by manual control Control of an external rinsing valve Three potential-free relays for: External rinsing valve control Limit value evaluation External control and / or alarm processing Safety check for 72 hours 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

The Testomat® 808 SiO₂ from Heyl is a device developed for measuring and monitoring deionized water in medical facilities. The central importance of silicate monitoring Silicate measurement using the Testomat® 808 SiO₂ is an essential aspect of compliance with a defined limit value. Precise silicate monitoring is particularly important in process water treatment in clinics in order to prevent deposits on equipment and medical devices (MD) and to ensure the effectiveness of water treatment systems. The limit value can be set in resolution steps of 0.1 mg/l free in the working range of 0.3–1.2 mg/l. Continuous monitoring of the silicate content and compliance with the limit values allows problems to be detected at an early stage and appropriate measures to be taken to protect the equipment and treated medical devices. The Testomat® 808 SiO₂ scores with: Low reagent consumption (up to 750 analyses with one reagent set), Ease of maintenance, Very good integration into PLC/PLC through transmission of measured values and error messages using fixed mA values Performance profile: The S7 function switch can be used to set 10 limit values from 0.3 to 1.2 ppm SIO2 Analysis triggering: o Automatic interval operation (with S8, the interval pause can be set from 0 to 480 minutes) o External control (start/stop input) o Manual analysis trigger (manual start) Long operating times thanks to 500 ml indicator supply RS232 interface for optional firmware updates and data output to a computer Weekend operation monitoring through 72 hours of unattended operation (BOB) Output of status and error messages via a current interface It is an efficient and practical solution with an excellent price-performance ratio, especially for critical processes such as in the semiconductor industry and deionized water treatment in clinics, hospitals, and outpatient centers. #BBD0E0 »

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 processing Safety 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 information Water 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 °C From 4 bar, a separately available pressure reducer must be used.
