1 Scope

This type of evaluation outline is applied to the electrode potential measurement of ion activity in solution ion gauge type evaluation. 2. References JJG757-2007 ion meter GB 4793.1-2007 measurement, control and laboratory safety requirements for electrical equipment - Part 1. General Claim GB/T 11606-2007 analytical instruments environmental test methods This outline document above for applications is essential.

3 Overview

Ion meter is a device for measuring ion activity in solution electrochemical analytical instruments. Ion meter and measured mainly by the electric meter The amount of the electrode composed of two parts. Electricity meter by the impedance converter, the potential of the amplifier, regulator and display components function measured Electrodes include ion selective electrode and reference electrode. Ion-selective electrodes ion activity in the solution is converted to potential root According to the Nernst equation obtained ion activity in solution. When measured by the ion activity of ions in solution, they are by comparison Measurement, first by measuring the standard solution, ion-selective electrode and reference electrode electromotive force of ions Meter calibration, and then use the same electrical measuring test solution, the electromotive force can be directly displayed as potential (MV) value can also be displayed as ion activity (pX) value or concentration (mol/L, g/L, mol/electric meter after conversion kg) value.

4 legal management requirements

4.1 units of measurement requirements Instruments should be legal units of measurement. 4.2 accuracy requirements Accuracy of the instrument rating shall comply JJG757-2007 "ionization gauge" requirement. 4.3 legal metrological requirements for marking and measuring instruments logo And other significant parts of the instrument panel should be marked on the nameplate or legal metrology marking and measuring instruments identified, marked, numbered And instructions must be clear, solid and reliable. 4.3.1 legal metrology signs generally include the following. a) measurement equipment manufacturing license logo and number (test prototype should be left corresponding position, only domestic instrument); b) measurement equipment type approval mark and number (non-mandatory provisions of this section, may leave the corresponding experimental prototype position).
