Overview
HI88703 is a High Accuracy multi-range laboratory turbidity measuring instrument, which can perform linear, nonlinear turbidity measurement and beer turbidity measurement, suitable for water industry, beer industry, etc. The instrument has different Measurement range options, low turbidity range (0.00 to 40.00NTU) and high turbidity range (0.00 to 4000NTU), especially in the low value range with extremely high accuracy and Accuracy, suitable for measurement of different concentration samples in different fields.
Features
1. Multi-range measurement, automatic range conversion
2. Linear turbidity, nonlinear turbidity measurement, beer turbidity measurement
Compliance with USEPA Standards and Standard Method 2130B
4. GLP management function, query settings, calibrate, time and other information
5.2, 3, 4, 5 point Manual calibration, built-in 5 point turbidity calibrating point
6. USB Interface, 200 Data storage, Data management
7. With chroma compensation, Illuminant automatic compensation function, avoid the interference caused by Illuminant fluctuation, no need to calibrate frequently
Principle
Turbidity refers to the scattering of light caused by tiny particles in water; the greater the turbidity, the greater the number of particles in the water. HI88703 adopts EPA custom Illuminant, and the microprocessor calculates the turbidity value by reaching the light intensity of the detector; it effectively corrects the interference of Color, and has the functions of chroma compensation and Illuminant automatic compensation. The light path design of HI88703 effectively reduces the stray light, so that the instrument can ensure excellent accuracy, precision and Reliability in low turbidity measurement.
Applications
Water industry, beer industry
Standards
USEPA 180.1 Standard Method 2130B
Steps
1. Use HI88703-11 turbidity calibrating group (turbidity scale: ≤ 0.10, 15, 100, 750, 2000 NTU) for calibration and calibrating
2. Measurement mode: normal measurement, continuous measurement or average measurement
3. Manual calibration, selectable 2, 3, 4, 5 point calibrating
4. Start measurement, the instrument automatically performs range conversion
5. Data management and storage via USB Interface
Notice
• Use a special calibrating group to calibrate regularly to ensure instrument accuracy
• If no operation is done for 15 minutes, the instrument will automatically shut down.
• Operating Environment Temperature 0 to 50 ℃, relative humidity up to 95%, no condensation
• Be careful to avoid the effect of stray light on low turbidity measurement
• Regularly check the Illuminant System to ensure Measurement accuracy
