Single Parameter Check – Chlorine, Total, Ultra Low & Ultra High
- Handheld Colorimeters
- Easier to use and more accurate than chemical test kits
- Dedicated to a single parameter
- Small size, big convenience
Ideal for :
- Swimming pools and spas
- Fruit and vegetable sanitation/ disinfection
- Drinking water
- Quality control checks
- Food processing
Chlorine is the most common water disinfectant. The monitoring of chlorine is crucial in applications such as swimming pools and spas, fruit and vegetable sanitation, disinfection and drinking water. By monitoring this crucial parameter, serious health and safety risks can be avoided.
The HI711, HI761, and HI771 Checker®HC Handheld Colorimeters bridge the gap between simple chemical test kits and professional instrumentation. Chemical test kits are not very accurate and only give 5 to 10 points resolution, while professional instrumentation can cost hundreds of dollars and can be time consuming to calibrate and maintain. Hanna’s Checker®HC’s are an accurate and affordable alternative.
The contoured style of these Checkers fit easily in the palm of your hand or pocket and the large LCD is easy to read. The auto shut-off feature assures the battery life will not be drained if you forget to turn it off.
These Checkers®HC’s are designed to be portable and easy to use, providing quick, accurate results in four easy steps.
