The Mettler-Toledo Thornton pHure Sensor Liquid Elecrolyte (LE) for M300, M800 and M300 ISM uses free flowing liquid electrolyte to provide the most accurate pH measurement available in pure waters. The electrode includes a special pH glass membrane, an integral, fast-responding temperature sensor, and AK9 or VP cable connections. All components of the pHure Sensor LE have been optimized for low conductivity performance and value and conform to ASTM Standard D5128. Various lengths of cable can be selected to provide flexibility in locating the sensor.
