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)
