ACCURATE AND AFFORDABLE CHLORINE MEASUREMENT
Chlorine is the most common water disinfectant. Therefore the monitoring of chlorine is crucial in applications such as swimming pools and spas, fruit and vegetable sanitation, disinfection and drinking water. Serious health and safety risks can be avoided by monitoring this crucial parameter. Chemical test kits are not very precise and only give 5 to 10 points resolution, while professional instrumentation can be expensive, costing hundreds of dollars, and can be time consuming to both calibrate and maintain. The HANNA HI 701 Checker®HC’s is accurate and affordable. This Checker®HC portable handheld colorimeter features a resolution of 0.01 ppm (250 points) and 3% ±0.03 ppm (mg/L) accuracy of reading. Checker®HC also uses an EPA approved DPD method. The contoured style of these Checker®HC’s fit in your palm and pocket perfectly and boast a large LCD that is easy to read. The auto shut-off feature assures the battery life will not be drained if you forget to turn it off.
The Checker is extremely simple to use. First, zero the instrument with your water sample. Next, add the reagent. Last, Place the vial into the Checker®HC, press the button and read the results. It’s that simple and easy!
