The high-range phosphorus pocket meter (0 to 15.0 ppm), HANNA Checker HI706, is a digital colorimeter for performing phosphorus tests.

The high-range phosphorus Checker, HI706, comes supplied with 2 cuvettes with caps, reagent for 20 tests, a battery, instructions, and a quick start guide.

• Accurate and simple measurements

• Direct on-screen display of phosphorus values

• Also available: ultra low-range phosphorus meter (HI736)

The HI706 phosphorus meter sits right between simple test kits and professional photometers.
It features a very convenient design—small enough to fit in the palm of your hand and easily portable in your pocket. Its large, easy-to-read LCD screen and automatic shut-off function help preserve battery life if you forget to turn it off.

HANNA Checkers are compact, portable, and—most importantly—provide more accurate results than typical chemical test kits. With enhanced technology and a user-friendly design, they allow for easy, hassle-free measurements.

These digital photometers, or test kits, bridge the gap between very basic visual test kits and professional instrumentation, such as a calibratable photometer.
Conventional test kits are not accurate and rely entirely on the user's interpretation of color, which is why HANNA has digitized this process, resulting in an accurate, pocket-sized digital colorimeter.

The Checker is both precise and highly affordable.
Its innovative shape fits comfortably in your hand or pocket. The LCD screen is easy to read, and the automatic shut-off function protects the battery if the device is left on.

Easier to use and more accurate than visual test kits:
• High accuracy
• Large, easy-to-read digits
• Automatic shut-off

Dedicated to a single parameter:
• Designed to work with HANNA reagents
