The Testomat 2000 Polymer is a professional online analyzer for automatic analysis of polyacrylate content in water. Photometric measurement is based on the addition of two reagents. After a reaction time of approx. 7 minutes, the result is displayed digitally and can be used for control or documentation. With menu-guided operation, unit selection (ppm or mg/L), and versatile triggering options, the analysis process is efficient and reliable. It is suitable for monitoring conditioning agents in cooling and heating circuits. Technical Features of the Testomat 2000 Polymer Automatic interval measurements, external control options, and programmable switching functions allow adaptation to various process requirements. Two independent switching points with hysteresis, adjustable maintenance intervals, and internal error documentation increase reliability in continuous operation.

Monitoring polymers ensures optimal dosing of conditioning agents, prevents deposits and fouling, and reliably protects water treatment equipment from operational disruptions. Chemical dosing must be monitored with a Testomat because its effectiveness is highly concentration-dependent. Continuous online monitoring ensures dosing stays within the optimal range, prevents under- or overdosing, and protects equipment, processes, and water quality reliably.

Testomat 2000 Self clean – Analyzer with Automatic Cleaning Water Hardness Meter from Heyl with Automatic Measurement Chamber Cleaning for Consistently Stable Results The Testomat 2000 Self clean is a specialized version of the Testomat 2000 with an additional dosing pump for adding a cleaning solution after analysis. After a set number of analyses, the measurement chamber is automatically rinsed and a cleaning solution is dosed to remove deposits in the measurement chamber and drain hose. The chamber content is discharged after a short reaction time, and the system is rinsed several more times. This ensures long-term measurement accuracy and device performance. The device measures various water parameters such as residual and total hardness, carbonate hardness, p-value, and minus m-value, with selectable units in °dH, °f, ppm CaCO3, or mmol/l. Special features of the Testomat 2000 Self clean With freely selectable hardness units, automatic interval control, and various external triggering options, the device can flexibly adapt to different measurement tasks. Two programmable limit values with hysteresis enhance process control, while the intuitive menu reduces operating errors and simplifies commissioning. Applications for the Testomat 2000 Self clean Boiler feed water Water treatment Cooling towers Swimming pools Functions and performance features of the Testomat 2000 Self clean Easy menu-guided operation and programming via plain text display Measurement of residual hardness, total hardness, carbonate hardness, minus m-value, and p-value selectable via indicator Choice of hardness units in °dH, °f, ppm CaCO3, or mmol/l High measurement accuracy through precise piston dosing pump Analysis triggering: Automatic interval operation (interval pause adjustable from 0–99 minutes) External control Dynamic (exhaust-dependent interval operation) Flow-dependent via water meter Two independent limit values with hysteresis (1, 2, or 3 bad analyses) and adjustable switching functions Monitoring of two measuring points (switching via external solenoid valves) Internal error documentation Programmable service address Indicator quantities: 100 and 500 ml bottles Programmable maintenance interval for service request
