This manual provides operation instructions, calibration methods, and measurement precautions for ATAGO 1T, 2T, 3T, and 4T Abbe refractometers.
This document serves as a brief operation manual for the ATAGO 1T, 2T, 3T, and 4T Abbe refractometers. It covers essential procedures for calibrating the instrument using test plates or distilled water, as well as step-by-step instructions for measuring refractive indices of both solid and liquid samples. This manual is written in Chinese.
| Refractive Index Range (1T/2T/4T) | 1.3000~1.7000 |
|---|---|
| Refractive Index Range (3T) | 1.30000~1.71000 |
| Brix Range | 0.0 ～95.0% |
| Refractive Index Accuracy (1T/2T/4T) | ±0.0002 |
| Refractive Index Accuracy (3T) | ±0.0001 |
| Temperature Range (1T/2T/3T/4T) | 0.0～50.0℃ |
| Temperature Range (2T) | 0.0～120.0℃ |
Use a test plate and bromonaphthalene to align the scale reading with the known refractive index of the plate.
Use distilled water at 20°C and adjust the scale reading to exactly 1.3330.
The minimum scale division for Brix is 0.5% for standard models and 0.1% for the precision model.
