The electrode is made of pH glass and a reference electrode combined composite electrode. It is widely used in various fields to measure pH levels. The Model is E-201. The Measuring range is 0 ~ 14pH and the Temperature is 0 ~ 60 C,Zero pH value 7 ± 0.25pH, Ambient temperature is 5-40 degrees, Relative humidity is 85%.Tested before removing the electrode protective sleeve (kit solution is 3MKCL, if there are crystals oozing is normal and does not affect the use of electrodes),Observed whether all sensitive bulb filled with liquid inside, if there is a bubble, you should gently shake the electrode downward (like rejection thermometer) to remove air bubbles inside the sensitive bulb, otherwise it will affect test accuracy. The Package includes 1x BNC Connector Electrode PH Probe Sensor
