The pH electrode InLab® Pure Pro-ISM from Mettler-Toledo has a glass shaft, temperature sensor, and a MultiPin™ plug. The sensor has a fixed glass sleeve junction and is developed for ion-weak samples like ultra-pure water and deionized water. The special membrane glass and the large membrane surface make it ideal for measurements at low temperatures as well. With high electrolyte outflow and refillable liquid electrolyte. Shipped without cable.

ISM - Intelligent Sensor Management: When the electrode is connected to an ISM-compatible instrument, it offers the option for safe and automatic documentation. The calibration data and sensor ID for the ISM sensor is automatocally transferred to the instrument, and the sensor saves the factory-issued calibration, as well as the latest 5 calibrations. In addition, the maximum temperature that the sensor has been exposed to, will be logged.
