Response time during temperature stage（10℃）:<3Score reached90%
stabilization time（0.02pH/10S）:50uS/cm

note:Technical specifications should not be considered in isolation.For example, measuring at room temperature,pHThe scope can be expanded to0～14pH.

The unstable trend of the standard electrode shows the cumulative contamination of the reference electrode.The curve indicates that traditional electrodes have0.1～0.4pHThe error between them,ButTempressThe reading is very stable.
