Measurement Range and Repeatability
Unit : mass%
| Component | Measurable range | Repeatability | |
|---|---|---|---|
| 1st solution | HNO3 | 30.0 - 34.0 | ±0.5 |
| HF | 2.00 - 4.00 | ±0.10 | |
| H3PO4 | 35.0 - 39.0 | ±0.6 | |
| H2SiF6 | 0.00 - 3.00 | ±0.50 | |
| H2O | 25.0 - 33.0 | ±1.0 |
Conditions of measurement
1) Measurement interval: approx. 8 sec.
2) Moving average time :10 times
3) Atmospheric temperature, chemical temperature fluctuation: within +/- 1 degree C (period of time: 1hour). Sudden temperature change should be avoided
4) Condition of sample temperature: 20 to 30 degree C
- Repeatability is the maximum deviation from average measured value over a 1 hour continuous measurement period.
- The values in the above table are assigned analog output values between 4 - 20 mA. (makimum resistance of 500Ω)
