The document is an instruction manual for the Hanna Instruments HI 736 Phosphorus Ultra Low Range meter. It details the functional description of the device components, lists included accessories such as sample cuvettes and reagents, and explains various error warnings like 'Light High' or 'Over Range'.
The guide covers the complete measurement procedure for determining phosphorus concentration in ppb using a specific reagent set (HI 736-25). It also provides instructions for battery management, including how to replace the AAA batteries when they are low or dead.
| Range | 0 to 200 ppb |
|---|---|
| Resolution | 1 ppb |
| Light Source | LED @ 525 nm |
| Dimensions | 81.5 x 61 x 37.5 mm |
One fresh battery lasts for a minimum of 5000 measurements, depending on the light level.
A flashing value of the maximum concentration indicates an over range condition, meaning the sample must be diluted.
