The Mettler Toledo InLab Expert pH Electrode, S7 (35900-05) is a general-use combination pH electrode cross-referenced to Mettler Toledo manufacturer part 51343100. It features an S7 connector, PEEK body, open reference junction, ARGENTHAL reference system and non-refillable XEROLYT polymer electrolyte for reliable pH measurement in complex or dirty samples.
Key Features
- Wide pH measuring range, covering pH 0 to 14 for general laboratory applications
- 0 to 100 °C temperature range, supporting measurements across common laboratory sample conditions
- Open reference junction, helping reduce clogging when working with dirty or complex samples
- ARGENTHAL reference system, using an Ag+ trap to support stable reference performance
- Non-refillable XEROLYT polymer electrolyte, providing a low-maintenance electrode design
- PEEK electrode body, offering chemical and mechanical robustness compared with glass-bodied probes
- S7 sensor connector, allowing the correct detachable sensor cable to be selected for the meter
- Universal U sensing glass, designed for standard pH measurement applications
- 12 mm shaft diameter and 120 mm length, matching standard laboratory electrode handling formats
- Cable not included, so users can select the suitable S7 cable connection for their meter
Note: The verified specification for Mettler Toledo 51343100 lists Intelligent Sensor Management as No and no temperature probe. A suitable detachable S7 cable must be selected separately.
Benefits
