Cooling and Boiler Combination Test Kit

The HI-3821 combination test kit includes all the necessary reagents to test these parameters. The kit allows you to perform over 100 tests for each parameter (50 for phosphate). All reagent bottles are numerically labelled for ease of operation and will allow you to avoid mistakes.

Boilers can be complicated systems to maintain. It seems easy enough that water heats to steam, and that steam provides power. For such a seemingly simplistic operation, care and maintenance can be anything but simple. Proper boiler treatment can prevent or correct a multitude of hazardous and costly situations.
