GB/T 2750-2011 《》 Related products

The GB/T 2750-2011 standard specifies composite Glass electrodes for pH value determination in aqueous solutions, covering electrode classification, technical requirements, test methods, inspection rules, etc. The performance indicators of standard Counter electrodes, such as Response time, internal resistance, alkali error, etc., are specified in detail. The classification includes laboratory type and online type, and is divided into normal temperature type and high temperature type according to the use environment and Temperature range. The standard also specifies the electrode Encasement, transportation and storage requirements to ensure that the electrode maintains stable performance under various conditions. Through this standard, the accuracy and Reliability of the composite Glass electrode in pH measurement can be ensured.
