Measurement Range and Repeatability

Unit : mass%

 ComponentMeasurable rangeRepeatability
1st solutionHNO330.0 - 34.0±0.5
HF2.00 - 4.00±0.10
H3PO435.0 - 39.0±0.6
H2SiF60.00 - 3.00±0.50
H2O25.0 - 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)
