Laboratory SensorsAnalog and digital laboratory sensors for benchtop and portable meters for measuring pH, conductivity and oxygen. Available in various materials and sensor lengths, with different types of connection, digital Memosens technology, and as specific laboratory sensors for food, water and environmental applications, or for the chemical and pharmaceutical sectors.
This liquid-filled sensor is designed for tough daily use in the lab. The sensor is ideal for rapid sample change and low sample temperatures. It also fits in an Erlenmeyer flask. The integrated temperature sensor automatically compensates the pH measurement for temperature variations when the sensor is used in samples at different temperatures.
With its plastic body and fiber junction, this sensor is very robust, which makes it ideal for environmental measurements and production-related quality control. Our standard sensor measures in media containing suspended solids or a high concentration of ions.
The new digital sensor with Memosens technology stores the calibration data in its head. Thus it is ready for measuring immediately and can simply be plugged into the Portavo device as needed. The inductive transfer of data for the first time lets you take measurements outdoors without having to worry about interference due to rain or contamination. The use of epoxy as the body material results in a high level of chemical resistance, and the dual ceramic junction ensures fast response times. Optimal positioning of the temperature sensor guarantees fast and precise temperature compensation during the measurement. An innovative feature of the SE 101 NMS is that it is equipped with a dual electrolyte junction, preventing the penetration of aggressive substances and thereby poisoning of the sensor, and increasing its service life considerably.
This liquid-filled sensor is designed for tough daily use in the lab. It is ideal for rapid sample change and low sample temperatures. Its length and its convenient gasket are optimized for use with devices of the Portavo series. The Portavo quiver keeps the sensor moist so that it is always ready to measure.
The new digital sensor with Memosens technology stores calibration data and diagnostics data directly in the sensor. Immediately after being plugged into the Portavo, it provides precise measuring results. The contactless inductive transmission of energy and data enables trouble-free outdoor measurements - without being affected by rain or dirt. The special gel filling speeds up the measurement time and reduces deposits on the junction. Sensor life is extended by an additional internal electrolyte bridge. At the same time, it prevents the penetration of aggressive substances and thereby poisoning of the sensor.
This liquid-filled sensor is designed for tough daily use in the lab. The sensor is ideal for rapid sample change and low sample temperatures. It also fits in an Erlenmeyer flask.
The ergonomically designed sensor has a robust body and allows perfect handling even in viscous samples. The reference system with open junction is arranged in a way that the measured value stabilizes immediately after sensor insertion.
For highly accurate measurements even in difficult samples. The ground-glass junction combined with the refillable liquid electrolyte provides a perfect contact and allows measuring at low conductivities or in coating media.
