Testomat® Module NH2CL photometer for monitoring monochloramine levels in cooling towers.

Precise hardness measurement in a compact format

The Testomat® Module TH is a powerful transducer for determining the total residual hardness in water. This is achieved through precise titration and photoelectric evaluation.

Particularly suitable for:

  • Water treatment plants
  • Process water monitoring
  • Systems with central control

Highlights:

  • Output via 4–20 mA or RS232
  • Fully automatic operation in interval mode
  • Can be networked with other Testomat® modules in a control room
  • Low space requirements and low-maintenance design
  • Easy parameterisation via service monitor and USB   

Efficient, reliable and intelligently networked. Ideal for applications that require stable water quality.
