The manufacturer of AquaChek test strips for pools and spas presents, among its new products, the new ShockChek testing strips that detect whether the water in your pool or spa needs a shock treatment (super chlorination).

This simple test differentiates between free chlorine and total chlorine. If there is a difference, it indicates the level of combined chlorine and recommends a shock treatment. Often poorly understood or wrongly used, a shock treatment clarifies cloudy water and restores its quality, destroys and prevents the formation of algae and bacteria and oxidizes contaminants and irritants present in the water.

The pool or spa water should be tested at least once a week, and whenever water conditions have altered. In fact, a shock treatment is necessary in case of heavy rain or storms, after a large influx of swimmers, or whenever the ShockChek test results or professionals responsible for the maintenance of the water recommend it.

The TruTest Spa digital indicator, a new product in the TruTest family, automatically assesses the reaction colour of the test strip and displays accurate test results on the LCD screen. It analyses the total amount of bromide, chlorine, total alkalinity and pH, and stores up to 9 test results.
The kit includes the measuring apparatus, sun protection, cord, and operating instructions. The test is designed to be quick, easy and accurate.
 

The Hach Pocket and Pocket Pro Pro+ digital meter models use sensor technology to measure salt, pH, TDS, conductivity, ORP and temperature. The Pocket Pro + meters are equipped with interchangeable sensors to make maintenance easy and extend the life of the unit. They run on AAA batteries.
