HI83306 Environmental Analysis Photometer and pH Meter

Product information "HI83306 Environmental Analysis Photometer and pH Meter"
Details

The HI83306 benchtop photometer measures 16 different key water quality parameters using 23 different methods. This photometer features an innovative optical system that uses LEDs, narrow band interference filters, focusing lens and both a silicon photodetector for absorbance measurement and a reference detector to maintain a consistent light source ensures accurate and repeatable photometric readings every time.

The HI83306 was developed to measure the most common parameters in environmental water quality monitoring. Nutrients such as nitrates and phosphates are key indicators of nutrient pollution from agricultural sources and are considered dangerous to environmental waters.Too few nutrients and waters will be unable to sustain healthy ecosystems; too many nutrients and algal blooms can form, which can be detrimental to water quality and aquatic health. Dissolved oxygen is an essential to performing biological processes for many forms of aquatic life, such as fish, plants and microorganisms.

A digital pH electrode input allows the user to measure pH by a traditional glass electrode. The digital pH electrode has a built in microchip within the probe that stores all of the calibration information. Having the calibration information stored in the probe allows for hot swapping of pH electrodes without having to recalibrate. All pH measurements are automatically compensated for temperature variations with a built in thermistor located in the tip of the sensing bulb for fast and accurate temperature measurement.

The HI83306 offers an absorbance measuring mode that allows for CAL Check standards to be used to validate the performance of the system. The absorbance mode allows the user to select one of the four wavelengths of light (420 nm, 525 nm, 575 nm, and 610 nm) to measure and plot their own concentration versus absorbance mode. This is useful for users with their own chemical method and for educators to teach the concept of absorbance by using the Beer-Lambert Law.

Two USB ports are provided for transferring data to a flash drive or computer and to use as a power source for the meter. For added convenience and portability the meter can also operate on an internal 3.7 VDC Lithium-polymer rechargeable battery.
