HI97713 is an advanced portable photometer for the low range measurement of phosphate (as orthophosphate) in water. This meter has a superior optical system that utilizes a reference detector and narrow band interference filters for extremely fast and repeatable measurements.
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.
Stable Light Source:
High Efficiency Light Source:
High Quality Filters:
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:
Mulitple Measurement Methods:
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:
Intuitive Dot Matrix Display:
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.
