The BlueLine family comprises three ranges of combination electrodes: Robust electrodes with gel electrolyte and plastic shaft for general use, liquid-electrolyte sensors for more critical measurements and special sensors.

• Special electrodes for redox measurements, surface measurements and food applications
• Gel electrolyte requires low maintenance and is not refillable
• ID sensors are equipped with a transponder, carrying the information of its type and serial number as well as the date and result of the last calibration
• IDS sensors automatically identify themselves with their serial numbers and type designation and transmit their calibration data when connected to a measuring device

pH range: 0 - 14
