InLab® Pro-DES pH Sensors and Signal Bridges

Supplier: Mettler - Toledo

DES® digital sensors are a smart choice. Retaining the measurement electronics and only replacing the sensor shaft at the end of its life, or the detachable cable that can be used for all sensors, helps reduce material waste and thus, the ecological footprint.
