Selection guide separate electrodes : Glass sensors
modelcode | Bulb type | Glass resistance （Mohm） | T range （°C） | Pressure （bar） | Applications | remark |
SM21（D）-AG2 | Universal | 25-50 | 0-80 | 10 | light laboratory | fast response high sensitivity |
SM21（D）-AG4 | shockproof | 50-100 | 0-100 | 10 | general | Universal |
SM21（D）-AG6 | heavy duty | 120-200 | 0-100 | 10 | Harsh | mechanically strong |
SM21（D）-AL4 | shockproof | 300-450 | 15-130 | 10 | High Temperature | T cont. ≥ 70°C high chem. Resistance |
SM21（D）-AL6 | heavy duty | 600-900 | 25-130 | 10 | High T + abbresive | T cont. ≥ 70°C high chem. Resistance |
* all pH glass sensors have a sodium error of 0.17 pH above pH=13 this because the glass then will see the Na+ ion as H+ ion. The pH reading is lower than it is in reality.
