Hanna Checker Digital Messgerät Freies Chlor 0 bis 2,50 ppm (HI 701)

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 HANNA HI 711 and HI 701 Checker®HC’s 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. The HANNA HI 711 and HI 701 Checker®HC’s are accurate and affordable.

These Checker®HC portable handheld colorimeters feature a resolution of 0.01 ppm (250 points for free chlorine, 350 for total chlorine) and ±3% of reading ±0.03 ppm (mg/L) accuracy. They also use an EPA approved DPD method.

The contoured style of these Checker®HC’s fit in your palm and pocket perfectly 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.

The HI 711 and HI 701 Checker®HC’s are 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 easy.

HI 701 Checker®HC is supplied with (2) sample cuvettes with caps, (6) powder reagents for Free Chlorine, (1) 1.5V AAA battery and instructions.
