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.

The original bottles allow direct use without transferring the solution. The Testomat® Indicator TH2005 is an original indicator solution for reliable measurement and threshold monitoring of residual hardness in the range of 0.05 to 0.50 °dH. Supplied in two practical 100-ml original bottles, the indicator enables direct application without transferring. The indicator is particularly suitable for applications with high water quality requirements, where precise monitoring of low hardness ranges is essential. Which devices is the TH2005 indicator from Heyl compatible with? The TH2005 indicator is compatible with the following measuring devices: Testomat 2000® Testomat 2000® CAL Testomat 2000® DUO Testomat 2000® V Testomat 2000® self clean Testomat ECO® Testomat ECO®-Plus Testomat® EVO TH Testomat® Limit Which values does the original TH2005 indicator from Heyl measure? The Testomat® Indicator TH2005 covers multiple units and offers high resolution: 0.05–0.50 °dH (Resolution 0.01) 0.09–0.89 °f (Resolution 0.02) 0.89–8.93 ppm CaCO₃ (Resolution 0.2) 0.01–0.09 mmol/l (Resolution 0.01) Using the original indicator ensures high measurement accuracy, proper device operation, and retention of warranty and guarantee claims. Häufige Fragen How long does the indicator/reagent last? The shelf life of an indicator is printed on the product label for each batch. In accordance with our terms and conditions, we deliver with a guaranteed minimum shelf life of 7 months. How much indicator is used per analysis? When it comes to indicator consumption, a distinction must first be made between TH indicators (e.g. TH 2005, 2025, 2050, etc.), which are used for the Testomat ECO, Testomat EVO TH, Testomat 2000 and Testomat Limit LT analysis devices, and the indicators for the Testomat 808 (300 series indicators, e.g. indicators 301, 305, etc.). The indicator consumption per analysis for the TH indicators is directly related to the limit value to be monitored. The higher this is, the higher the indicator consumption. For the Testomat 808 indicators (300 series), consumption is approximately 80 µl per analysis. By entering the operating data (analysis interval, limit value, etc.), the exact consumption or indicator requirement per year can be determined using our indicator consumption calculator: Indicators consumption calculator - Heyl Neomeris What sizes are available for the bottles and is there anything to bear in mind? The indicator is available in both 500 ml and 100 ml bottles. The analyser is delivered with the 500 ml bottle set up and the scope of delivery includes the screw cap with hole and insert for the screw cap of the 500 ml indicator bottle. For operation with 100 ml bottles, the bottle size must be changed to 100 ml in the basic programming and the screw cap with hole and insert for the indicator must also be purchased. For Testomat 808 devices, the conversion kit (item no. 37580) must be purchased for the use of 100 ml indicator bottles, and for Testomat 808 SiO2 devices, the insert with screw cap and suction tube (item no. 37645) and the hose connector ø 3.5 mm (item no. 37643) must be purchased. For all other Heylwelt Testomat devices, please use the conversion kit with item no. 40143. Where can I find the safety data sheet? The safety data sheets can be found in the online shop (www.heylneomeris.shop) under the menu item – Service/Help – Downloads – Safety data sheets. How can the indicator be disposed of? Disposal instructions can be found in section 13 of the safety data sheet. Disposal must be carried out in accordance with official regulations. Can the indicator still be used after the expiry date? The indicator can no longer be used after the expiry date. After the expiry date, accurate measurement results can no longer be guaranteed. What is the optimum storage temperature for the indicator? Section 7 of the safety data sheet contains all relevant information on storing the indicator. The recommended storage temperature should be between 15-25°C. Device warranty / guarantee Measurement errors when using third-party indicators! The use of third-party indicators can lead to large measurement deviations or measurement errors. Damage caused by foreign particles in the area of the dosing pump, measuring chamber or valves is also possible. The use of third-party indicators will void the warranty!
