HI-97713 Phosphate Low Range Portable Photometer with CAL Check

his meter offers a superior optical system that utilises a reference detector and narrow band interference filters for extremely fast and repeatable measurements.

Measurement method: Adaptation of the Ascorbic Acid method.

About the HI-97713 phosphate low range portable photometer

• Range: 0.00 to 2.50 mg/L (as PO₄^3-
• 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™ - 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.
• Unit of measure – 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.
