HI-97717C Phosphate High Range Photometer Kit

About the photometer

The HI-97717 has an innovative optical system that offers superior performance in accuracy, repeatability, and the short amount of time it takes to perform a measurement. This compact, waterproof meter is extremely user friendly with a tutorial mode that walks the user graphically, step by step, in performing a measurement. The use of a backlit dot matrix LED allows the use of virtual keys which makes the operation of the meter very intuitive including selecting different methods, reviewing GLP data, recalling the last 50 measurements, and customising the meter to user preferences.

HI-97717 is waterproof including the cuvette holder that is designed with ridges to protect the optical path from getting scratched by the cuvette and a protected battery compartment that holds three AA batteries. The compact design fits comfortable in the hand for use in the field or on a table for benchtop use. The LCD is 71 mm (2.75") by 37 mm (1.6") and is backlit for easy viewing under all conditions.

Advanced LED optical system

LEDs have a much higher luminous efficiency, providing more light while using less power. They also produce little heat which could otherwise affect electronic stability.

CAL Check^TM

Validate the performance of the instrument at any time and apply a user calibration using CAL Check cuvettes made with NIST traceable standards.

The CAL Check screen guides the user step-by-step through the validation process and user calibration.

Auto logging

GLP

Review of the last calibration date.

On-screen tutorial mode with animations

The built in tutorial mode guides users step-by-step through the measurement process.

Waterproof and floating IP67 case

Auto-shut off

Automatic shut off after 15 minutes of inactivity and 30 minutes before a read measurement.

Battery status indicator

Indicates the amount of battery life left.

Built-in timer

Display of time remaining before a measurement is taken. Ensures that all readings are taken at the appropriate reaction intervals for the test being performed.

Error messages

Messages on display alerting to problems including no cap, high zero, and standard too low.

Units of measurement

Appropriate unit of measure is displayed along with reading.

About Phosphates

Phosphates are used in a number of everyday products. Such as cola drinks to enhance flavour and tartness, antifreeze as a pH buffer, and French fries to delaying darkening of the cut potatoes. They are also extensively used in detergents and cleaning fluids because of their ability to soften water and remove soil deposits.

Phosphate is essential for the growth and development of plant roots, stems, flowers and seeds, hence why it is one of the most commonly added to fertilisers. However, high concentrations of phosphates in agricultural runoff can cause environmental pollution, as they are a primary cause of eutrophication. Local laws govern the use of phosphates and the discharge levels into streams and waterways.
