Residual hardness °dH

The Durognost SR Threshold Test Kit is a simple set for quickly checking whether water hardness levels fall within the range of 0.25 to 0.5 °dH. Check water hardness quickly Special liquid indicator in a dropper bottle for monitoring residual hardness in softened water, calibrated to the limit values of 0.5 and 0.25 °dH (8.9 and 4.47 ppm). With the Durognost SR kit, you can easily determine whether your water falls within this very soft hardness range. The indicator powder changes colour as soon as the water hardness limit is reached or deviates from it. This gives you a clear result quickly. This set allows for approximately 250 analyses. The kit is only suitable if you wish to check whether the water hardness is very low. If you require exact numerical values, this kit is not suitable. Quick test without laboratory equipment First, rinse the measuring tube with the water sample. Then fill the tube with the water sample up to the 5 ml or 10 ml mark. Add one drop of indicator and mix it thoroughly with the water sample by gently swirling the tube. After approx. 30 seconds, the water sample will change colour. Water sample colour: Green = softened water is fine Red = Regenerate the water softener Please note: When comparing the result with the enclosed table, it is essential to take the selected sample volume (5 ml or 10 ml) into account. Please read the enclosed instructions for use carefully before use.

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. Please use only the indicators approved for Testomat® 808! Optional accessories:  NeoTecMaster unit hood Frequently asked questions How does the Testomat® 808 work for hardness measurement? With a color change for easy limit value monitoring. For which applications is this device particularly suitable? For osmosis systems, ultra-pure water systems, electroplating, soft water for commercial purposes, and boiler systems. How do I recognize a limit value exceedance? Through a clearly visible LED display. Can I integrate additional sensors into the system? Yes, easily possible with the right modules. How does the system support me in monitoring the installations? By centrally displaying values and messages. How flexible is the system's expansion? It can be modularly adapted and expanded. What makes this package particularly practical in everyday life? It combines simple measurement with central control.
