The Testomat ECO® C determines the carbonate hardness fully automatically by means of titration. In addition to monitoring and controlling the water quality of water treatment plants, the device is particularly suitable for determining the acid quality in swimming pool water at low measuring ranges. In combination with a hardening system, the instrument guarantees stable compliance with the parameters recommended in DIN 19643 of 0.7< KS4.3 < 2.0 mmol/l. Performance profil: 2-line LC display for text indication and self-explanatory, menu-guided user interfacefläche.Programmable hardness unit in °dH, °f, ppm CaCO3, mmol/lHigh-precision titration by means of piston metering pumpReliable and low-maintenance operationMinimal indicator and water consumption2 adjustable limit values with programmable switching functionsAnalysis initiation:automatic interval operation (0-99 minutes)quantity-dependent (contact water meter)Monitoring of analysis progress and error message in case of malfunctionsexternal analysis suppression "STOP"Two independent limits with hysteresis (1, 2 or 3 bad analyzes) and adjustable switching functions (2 neutral changer contacts)Analog output 0/4 - 20 mA for recorder connection
