Overview
HI93703-11 Portable dual-range turbidity tester complies with ISO7027 measurement standards, with low turbidity range (0.0 - 50.00FTU) and high turbidity range (50 - 1000FTU) automatic conversion measurement function. Built-in excellent Optical inspection system, with special large Cuvette and shading measurement tank, the Illuminant pass rate is higher and the effect of Illuminant fluctuation and stray light is effectively reduced. AMCO-AEPA-1 special turbidity calibration group is non-toxic and harmless, stable performance, can be stored for a long time, and can be used for repeability. It is used for regular calibration of internal calibrate Linear dispersion to ensure accurate instrument measurement. It is widely used in water quality monitoring, wastewater field and laboratory measurement.
Features
1. Automatic range conversion, built-in turbidity standard calibrating point to ensure measurement accuracy
2. Unique GLP management function, can automatically store the last calibrated date
3. Comply with ISO7027 turbidity standard, FTU is formazid turbidity unit
4.199 Data storage, RS232 Interface, convenient data transmission, management and analysis
5. Battery power display, timely reminder to replace the battery, automatic shutdown power-saving mode
Principle
Optical inspection system consisting of silicon Photocell, photovoltaic cell and custom Infrared source (890nm) is used to determine turbidity value by measuring the degree of scattering of the sample to specific wavelengths of light. With special large Cuvette and shading measurement slot, the Illuminant pass rate is improved and the influence of Illuminant fluctuation and stray light is reduced to ensure the accuracy of measurement results.
Applications
Water quality monitoring, wastewater field, laboratory measurement
Standards
ISO7027 turbidity measurement standard
Steps
1. Boot preparation: Load 4 1.5V AA batteries
2. calibrating operation: manual 3 point calibrating (0FTU, 10FTU, 500FTU calibrating point)
3. Sample measurement: put the sample into the special Cuvette and place it in the shading measurement groove for measurement
4. Data management: Transfer data through RS232 interface or view the stored 199 sets of measurement data
5. Shut down: The instrument automatically shuts down after 5 minutes of no operation
Notice
• It needs to be calibrated before use to ensure measurement accuracy
• Regularly calibrate with AMCO-AEPA-1 special turbidity calibration group
• Pay attention to the battery level display and replace the battery in time
• Operating Ambient Temperature should be in the range of 0 ° C-50 ° C, Humidity should not exceed 95% RH and no condensation
• If the instrument does not operate for 5 minutes, it will automatically shut down to save power.
