• Instruction manual WARRANTY The HI 731327 complete maintenance kit is also available, including: HI 93102 is guaranteed for two years against defects in workmanship • 2 glass cuvettes and materials when used for their intended purpose and maintained • Primary calibration standards: according to instructions. -
Page 3: General Description
• Battery status is monitored during every measurement cycle warning the user if the batteries become weak. In addition, HI 93102 will turn itself off before low voltage causes erroneous readings. • It utilizes a real time clock and recalls calibration data such as date, time and calibration values. -

(light) of its TURBIDITY MODE molecules. HI 93102 has been designed to perform measurements according to Colorimetric analysis is based on the principle that specific compounds the USEPA’s 180.1 method and the Standard Method 2130B. -
Page 5: Functional Description
A substance absorbs a color complimentary to the color it emits. For FUNCTIONAL DESCRIPTION example, a substance appears yellow because it absorbs blue light. As a result, the Hanna meters use LED’s with specific wavelengths to measure samples. The optical distance (d) is measured by the internal diameter of the cuvette containing the sample. - Page 6 2) Secondary meter will quit diagnostic mode. If pressed LCD: The three-digit LCD shows the current for more then 3 seconds, an intermittent mode of measurement that is “F CL”, “CAL” prompt will appear on the “tCL”, “CY”, “PH”, “Id”, “Br”, “LFE”, upper LCD level and the calibration “tr”, and diagnostic or calibration modes, procedure is entered.
