Overview
The HI97750 Potassium/oxidation Potassium Portable Photometer is an instrument for the measurement of potassium oxidation (K 2O O) content in water. Potassium oxidation plays an important role in agriculture and soil science, and is often used in the analysis of soils and agricultural products to assess soil fertility and crop nutrient status. It can also be used to monitor potassium oxidation content in industrial wastewater. The instrument is IP67 waterproof and designed with an innovative Optical inspection system with good accuracy and repeatability. The CAL CheckTM function allows performance verification and calibrating using NIST traceability standards. Built-in reaction Timer, GLP display, battery status indication and automatic shutdown function.
Features
1. LED high quality Illuminant system with good performance and high luminous efficiency;
2. High Quality Optical inspection Filter, Provides High Measurement Stability and Less Wavelength Error to Ensure Accuracy and Accuracy;
3. Unique reference detector for fast stabilization of readings between blank (zero) measurement and sample measurement;
4. Stable Illuminant Settings to Reduce Errors and Reading Offsets Caused by Glass Colorimetric Cup Defects;
5. CAL CheckTM function, support performance verification and calibrating.
Principle
The HI97750 Potassium/potassium oxidation Portable Photometer is based on an improved method of tetraphenyl Boricacid ester Turbidimetry for measurement. The instrument uses an LED Illuminant to illuminate the sample at a wavelength of 466nm and detects changes in light absorption or scattering through a silicon Illuminant and Optical inspection filter to determine oxidation potassium concentration. A unique reference detector and stable Illuminant setting ensure fast and stable measurement with reduced errors.
Applications
Soil analysis, agricultural product analysis, wastewater monitoring
Standards
IP67 waterproof standard
Steps
1. Turn on the instrument power supply;
2. Use the CAL CheckTM function for performance verification or calibrating;
3. Prepare the sample and place it in the reaction cup.
4. Start the built-in reaction Timer for measurement;
5. Read the measurement results on the display screen;
6. The data is automatically stored, and the last 50 measurement records can be viewed.
Notice
Make sure the battery is in good condition and use 1.5V AA batteries (3 pcs).
• The instrument automatically shuts down after 15 minutes of no operation to save power;
• Ambient Temperature should be in the range of 0 to 50 ° C during measurement, and the relative humidity should not exceed 100%;
• Regularly use the CAL CheckTM function to verify instrument performance;
• Avoid severe impact or immersion beyond the IP67 standard range;
• Follow Good Laboratory Practice (GLP) and calibrate the date and time display.
