Table 5 Specifications of ammonia electrode
*1: The measurement accuracy is the difference between the measured value
and the assigned value of the 100 mg/L standard solution after the two
points calibration using the 10 mg/L and the 100 mg/L standard solutions.
The temperature in the calibration and in the measurement is 25°C
*2: The ion concentration value enclosed in ( ) is the measurable pH tolerance
range.
However, the tolerance range differs depending on the ion concentration.
*3: This is the electrode potential gradient in the calibration using the 10 mg/L
and the 100 mg/L standard solutions at 25°C.
