HI97104 pH, Free Chlorine and Total Chlorine, Alkalinity, Cyanuric Acid Portable Photometer

HI97104 pH, Free Chlorine and Total Chlorine, Alkalinity, Cyanuric Acid Portable Photometer

Stable Light Source:

The internal reference system of the HI-97104 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.

HI-97104 is an advanced portable photometer for the measurement of pH, Alkalinity, free chlorine & total chlorine, and Cyanuric Acid in water. This meter offers a superior optical system that utilises a reference detector and narrow band interference filters for extremely fast and repeatable measurements.

  • No warm up time before taking a measurement
  • Tutorial mode for step-by-step instructions
  • Uses either powder or cost saving liquid reagents
  • CAL Check
