CARACTERíSTICAS DEL PRODUCTO

Phosphate is a common additive to water for its ability to protect iron pipes from corrosion. It can be found in both water for drinking and for boilers/cooling towers. The HI97713 uses an ascorbic acid method in which orthophosphate reacts with molybdate in an acid solution to form a yellow-colored phosphomolybdate complex. The phosphomolybdate complex is then reduced by ascorbic acid and as a result a blue color is produced that is proportional to the concentration of phosphate in the sample. The ascorbic acid method is ideal for measuring samples with a low concentration of phosphate. The HI97713 phosphate photometer can measure phosphate in water from 0.00 to 2.50 mg/L (ppm).

The HI97713 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 units of measure, reviewing GLP data, recalling the last 50 measurements, and customizing the meter to user preferences.

HI97713 is completely waterproof including the cuvette holder that is designed with ridges to protect the optical path from getting scratched by the cuvette and a gasketed battery compartment that holds three common 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.

LED that generates very little heat

8 nm narrowband interference filter that is accurate to +/- 1 nm and offers 25% increase in light efficiency.

Reference detector that modulates the voltage to LED for consistent light output.

A concave focusing lens that reduces errors from imperfections in the cuvette

HI97713 FEATURES/BENEFITS:

Stable Light Source:

The internal reference system of the HI97713 photometer compensates for any drifts due to power fluctuations or ambient temperature changes. With a stable source of light the readings are fast and stable between your blank (zero) measurement and sample measurement..

High Efficiency Light Source:

LED light sources offer superior performance compared to tungsten lamps. 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.

High Quality Filters:

Improved optical filters ensure greater wavelength accuracy and allow a brighter, stronger signal to be received. The end result is higher measurement stability and less wavelength error.

Greater Light Yield:

A focusing lens collects all of the light that exits the cuvette, eliminating errors from imperfections and scratches that may be present in the glass. The use of the convex lens reduces the need for indexing cuvettes..

CAL Check Functionality:

Hanna’s exclusive CAL Check feature allows for performance verification and calibration of the meter using NIST traceable standards. Our CAL Check standard vials are developed to simulate a specific absorbance value at each wavelength to verify the accuracy of subsequent readings.

Mulitple Measurement Methods:

Users can select the unit of measure displayed including as phosphate-phosphorous (PO₄^-3-P), phosphate (PO₄^-3), or as phosphorous pentoxide (P₂O₅).

Built-in Reaction Timer:

Waiting the proper reaction time is of key importance when performing colorimetric measurements. The countdown timer displays the time remaining until a measurement will be taken, ensuring consistent results between sample measurements and users.

Large Cuvette Size:

The sample cell of the HI97713 fits a round, glass cuvette with a 25 mm path length. The relatively long path length of the sample cuvette allows the light to pass through more of the sample solution, ensuring accurate measurements even in low absorbance samples.

Intuitive Dot Matrix Display:

The HI97713 is designed with a backlit, graphic LCD. With virtual keys, a battery status indicator, and error messages. Users will find the meter interface intuitive and easy to read. A dedicated help key provides information relating to the current meter operation, and can be used at any stage in the setup or measurement process to show contextual help.

Auto-off Protection:

The meter uses three common AA batteries that allow for about 800 measurements to be taken. The auto-off feature automatically shuts off the meter after 15 minutes of inactivity in order conserve battery life.
