Overview
The HI96831 ethylene glycol (glycol) freezing point refractometer uses the refractive index measurement method to determine the volume percentage and solidification point of ethylene glycol solution by measuring the refractive index. Simple operation, fast analysis, provides a good method for the measurement of ethylene glycol concentration and freezing point. The digital refractometer eliminates the uncertainty of mechanical refractometers. Users can use distillation water or deionized water to simply calibrate the measurement. Within a few seconds, the refractive index and temperature are converted into% volume or solidification point units. Internationally recognized reference materials for ethylene glycol solution unit conversion and temperature compensation are used.
Features
1. Measured values and temperature readings are displayed simultaneously on a dual-row LCD display
2. ATC automatic temperature compensation
3. Easy measurement, press READ button after dropping the sample
4. BEPS reminds that low battery power may affect the reading
5. IP65 waterproof, suitable for harsh laboratory and field conditions
6. Fast and accurate, readings are displayed in about 1.5 seconds
7. Single point calibrated, using distillation or deionized water
8. Trace samples, only 2 drops of sample required
9. Automatic shutdown, no automatic shutdown for three minutes
10. Stainless steel sample chamber, resistant to saline water corrosion
Principle
The instrument uses the refractive index measurement method to determine the volume percentage and solidification point of ethylene glycol solution by measuring the refractive index. During measurement, the refractive index and temperature data are collected at the same time, and automatically converted into% volume or solidification point units. The internationally recognized ethylene glycol solution unit conversion and temperature compensation reference materials are used for data processing.
Applications
Ethylene glycol solution concentration measurement, ethylene glycol freezing point determination
Standards
CRC Handbook of Chemistry and Physics 87th Edition
Steps
1. Use distillation or deionized water for calibrating
2. Drop a few drops of sample into the sample well
3. Press the READ button to start the measurement
4. Read the measurement results on the LCD display
Notice
• Use distillation or deionized water calibrated before use
Low battery level may affect reading accuracy
The sample size should be completely covered by the prism (minimum 100 μL).
• The instrument will automatically shut down without three minutes
• Note that the temperature compensation range is 0-40 ° C (32-104 ° F)
