Digital pH sensor WSPH 1912

Basic Principle of pH Electrode In PH measurement, the used electrode is also known as the primary battery. The primary battery is a system, whose role is to transfer chemical energy into electrical energy. The voltage of the battery is called the electromotive force (EMF). This electromotive force (EMF) is composed of two half-batteries. One half-battery is called the measuring electrode, and its potential is related to the specific ion activity; the other half-battery is the reference battery, often called the reference electrode, which is generally interlinked with the measurement solution, and connected to the measuring instrument. Features 1) Extremely quickly and precision electrical conductivity sensor. 2) It's suitable for harsh application and free-maintenance,save cost. 3) Provide two ways of 4-20mA output for EC and temperature. 4) Digital EC Sensor provide precision and online measurement. 5) With data recording function,user easy to check history data and history curve. Electrode tip bottle have adequate protective 3.3 M KCL bubble solution, the electrode tip soaks inside,in order to keep the glass bulb and the liquid junction activating, loosen protective bottles, pull out the electrode, wash with deionized water beofre measure. 1. Throw off the air bubbles within the glass bulb, otherwise it will cause measurement errors, stir the test solution with electrode to accelerate response when measuring, then place the electrode. 2.Check the joints dry and clean or not, if soiled, use ethanol clean and blow to dry before use.
