一、测量方法依据JJG822-1993《钠离子计》检定规程。钠离子计检定采用直接测量法,电计检定用PH检定仪向电计输入相应的标准直流mV电位或PNa值,根据输入值计算电计的示值误差。配套检定用一种标准溶液校准后,测量另一种标准溶液。
First, the measurement method based on JJG822-1993 “sodium ion meter” test procedures. Sodium ion meter test using direct measurement method, the electrometer test with PH meter to enter the corresponding standard DC mV potential or PNa value, according to the input value of the electrical meter indication error. Auxiliary test After calibration with a standard solution, measure another standard solution.
