SM60-T1工业电极

日本横河SM60-T1工业电极

■ Overview 

For accurate pH measurement temperature compensation is required. A Pt 1000 temperature electrode can be selected. 

pH measurements are temperature dependent from two different effects: 

• Variations with temperature on the contact potentials in the glass and the reference system 
• Temperature variations of the liquid being measured 

Therefore, it is necessary to include a temperature sensor in the system, whose purpose is to provide automatic compensation for the effects of temperature variations on the measuring system. The temperature compensator consists of a platinum resistance element (e.g. PT1000) mounted in a glass tube. The tube is filled with white silicon grease, the thermal conducting properties of which ensure fast temperature response. It is possible to manually compensate for temperature variations as an alternative to automatic temperature compensation.
