Testomat Limit TH and Testomat 808 in direct comparison

A comparison of the most important differences, advantages and areas of application

The Testomat Limit TH online analyser is the successor to Heyl's Testomat 808. The Limit TH automatically measures total hardness. Below, the two devices are compared directly with each other and the advantages of the Limit TH are highlighted.

What are the advantages of the Testomat Limit TH compared to the Testomat 808?

  • It has a TFT panel (touchscreen) with USB interface for firmware updates of the panel
  • Automatic venting function
  • Use of all hardness indicators from the proven Testomat 2000 series for a simple titration process
  • Error history via plain text display
  • Measurement value storage via SD card
  • Measuring chamber to prevent analysis interference from external light
  • Service-friendly thanks to quick-coupling system in the measuring chamber area and hydraulic hoses

Functions that remain unchanged:

Water detection is still visual. Both have a limit value output, an alarm output, an external reset/acknowledgement input for errors and alarms, an external stop input, and a monitorable measuring point and limit value exceedance. The devices have 72 hours of unattended operation (BOB).

Where can the Testomat Limit TH be used?

The Testomat Limit TH from Heyl can be used in the same areas of application as the Testomat 808.

Reverse osmosis system: To protect the membranes and extend the service life of the system.

Boiler feed water supply: Energy costs can be reduced and it protects the boilers from limescale deposits.

Soft water for commercial purposes: Equipment remains clean and efficient.

Ultrapure water systems: Water hardness measurement is crucial to ensure purity and protect sensitive applications.
