Closed System Weekly Test Kit

For weekly monitoring of closed industrial water systems

  • Ideal for regular checks on nitrite and pH levels
  • Prevents corrosion and scale
  • Accurate inhibitor dosage rates
  • Reproducible, accurate results

Closed water systems are closed to the greater environment and use very little Make Up (MU) water in their normal operation. A properly ‘tight’ system will have no more than 5 % MU water annually. Calcium based scale formation is not as significant a risk as corrosion is for these systems. The minimum recommended regular tests are:

  • Conductivity/TDS
  • pH
  • Iron (dissolved & total) Inhibitor (test as applicable)
  • Other metals (test as applicable)
  • Microbiological check(s)
  • Turbidity/Suspended Solids

Product information

The Closed Water Test Kit is designed for use on all types of closed water Systems such as chilled water circuits and heating systems.

The Kit should be used to monitor water conditions to ensure that the systems are under control and do not exhibit signs of corrosion, scaling or microbiological fouling.

The Closed Water Test Kit is supplied in its own robust carry case and includes all the equipment and reagents necessary to perform approx 100 tests.
