HI-701 Digital Chlorine Checker Tester

Hanna Instruments, manufacturer of measurement and analysis instruments, presents a new digital tester as a substitute for traditional free chlorine test kits, offering precise and simple measurements with a pocket-sized device.

The HI 701, Free Chlorine Digital Checker, performs measurements according to the Standard Method DPD.

Small in size, big on convenience.

Checker®HC units fit easily in the palm of your hand or your pocket and weigh only 64 grams.
Perfect for quick and accurate on-site testing.
One-button operation: zero and measure.
Powered by a single AAA battery.

The new Checker®HC units bridge the gap between disc colorimeters and professional instrumentation. Chemical test kits are not very accurate and provide only 5 to 10 resolution points, while professional instruments can be very expensive. Checker®HC units are both accurate and affordable.

The design of these Checker®HC units fits perfectly in your hand and pocket. The large LCD display provides clear readings. The auto-off function ensures battery longevity in case you forget to turn it off.

The Checker®HC units are extremely simple and easy to use. First, zero the instrument with your water sample, then add the reagent. Finally, place the vial in the Checker®HC, press the button, and read the result on the display.

These handheld photometers use the EPA-approved DPD method and are extremely easy to use:

• The HI 701 works with HANNA's powder reagents and uses 10 ml glass cuvettes. Use it for fast and accurate on-site measurements. Ideal for pool and spa control, fruit and vegetable sanitation, drinking water disinfection, and quality control.
