Testomat Automatic Hardness Control

Automatic hardness control
The Testomat automatic determines the residual/total hardness via titration. Ideal for the water quality after water softeners, water blender and drinking-water plants.
The Testomat EVO TH is the successor to the Testomat ECO.

- Easy to operate
- Automatic venting
- Measures total or residual hardness
- Available version with a calibration function
- Optical water detection
- Open drain
- SD card
- Self-test
- RS232 port
- External alarm clearing

The Testomat Family
Automatically determines the residual or total water hardness, the carbonate hardness, the p-value or the minus-m-value via titration. The 2000 can measure two individual measuring points.
This analysis instrument enables the measurement of two different parameters simultaneous, e.g. two different measuring ranges for water hardness.
This Testomat correspond in function and suitability to the Testomat 2000, but has an additional calibration function in order to balance possible interference.
This Testomat is "the good value alternative" for the Testomat 2000, it determines through titration the water hardness from a single measurement point. The Testomat Eco or Testomat 2000 replace the Testomat F-bob
This Testomat version, in combination with a 3/2-way-motor operating valve is an easy to use control system for water blending plant
The process-photometer Testomat 2000 CLT is a wet-chemical online instrument for monitoring the content of total chlorine in the 0–2.5 mg/l (ppm) range and it can be switched to free chlorine.
• Analysis via automatic dosing of 3 reagents; the analysis result is displayed after a reaction time of approx. two minutes
• Application areas: Monitoring of chlorination plants for drinking water or swimming pools– Provides protection for reverse osmosis membranes.
The process-photometer Testomat 2000 CLF is a wet-chemical online instrument for monitoring the content of free chlorine in the0–2.5 mg/l (ppm) range.
The process photometer Testomat 2000 THCL determines the content of total chlorine in the 0 to 2.5 mg/l (ppm) range using the colorimetric analysis principle and the existing water hardness via titration.
The process photometer Testomat 2000 Fe is a wet-chemical online monitor for monitoring the content of dissolved iron (II) + (III) in the 0 to 1.0 mg/l (ppm) range using the colorimetric method.
• Dosing of 2 reagents and display of the analysis value after a reaction time of approx. 7 minutes (absolute measuring time without flushing times)
