Overview
The HANNA HI93102 Turbidity Meter is a Multi-Parameter measurement system that provides rapid measurement of turbidity, chlorine, acidity pH, bromine, iron, iodine, and cyanuric acid (CYAC) for 7 water quality parameters. With a Portable design and laboratory-grade Measurement accuracy, it is widely used in water quality analysis and drinking water quality monitoring.
Features
1. Excellent Optical inspection system design, humanized operation, to ensure that the instrument is well calibrated
2. Manual calibration, built-in standard calibrating point: 0, 20NTU, in line with USEPA method
3. Built-in standard Linear dispersion calibration before leaving the factory, with CAL CHECK performance verification function
4. GLP function, update and consult calibration data, dates, standards and other information at any time
5. Reagent and sample reaction time conformity to ensure Measuring accuracy
6. High Accuracy measurement results, Illuminant dust measurement system, Automatic shutdown power saving mode
Principle
The microprocessor calculates the turbidity value by the Light intensity reaching the detector, effectively corrects the Color interference, and has chroma compensation and Illuminant automatic compensation functions to avoid interference caused by Illuminant fluctuations without frequent calibrating. The turbidity measurement adopts the turbidity measurement method (90 ℃) or the scattering turbidity measurement method (90 ℃ & 180 ℃), which conforms to USEPA method 180.1 and standard 2130B.
Applications
Water quality analysis, drinking water quality monitoring
Standards
USEPA180.1、Standard Method 2130B
Steps
1. Manual calibration instrument with built-in standard calibrating point 0 and 20NTU
2. Conduct CAL CHECK performance verification
3. Utilize the GLP function to update and access calibration data, dates, standards, and other information
4. Reagent and sample reaction time conformity measurement
Notice
• The instrument is used in an environment of 0 to 50 ° C (32 to 122 ° F), with a maximum relative humidity of 95% and no condensation
• Measurement accuracy is affected by temperature, please refer to the accuracy index at 25 ℃
• Powered by 4x1.5V AA battery, pay attention to the automatic shutdown time setting (10, 20, 30, 40, 50, 60 minutes optional)
• Avoid Illuminant fluctuation interference, the instrument has automatic compensation function, no need to calibrate frequently
