The compact BlueLine range is a basic series comprising electrodes for the usual laboratory applications which makes the user’s choice easier.

An accurate and fast measurement is ensured by precision manufacturing and employment of high quality material, e.g. low-resistance A-type membrane glass or the unique platinum diaphragm.

The BlueLine family comprises three ranges of electrodes, the robust electrodes with gel electrolyte and plastic shaft for general use, the liquid-electrolyte sensors for more critical measurements and special sensors. The gel and the liquid electrolyte sensors are available with different connections (e.g. plug head or fixed cable with either DIN or BNC type plug) and with different cable lengths and also with built-in temperature sensors. The special electrodes range includes pH electrodes for surface measurements, for small sample amounts, for ultrapure water and emulsions or measurements in semi-solid samples also redox electrodes and a conductivity electrode for media with low ionic content.
