IDS conductivity measuring cell with universal plug head – digital & wireless ready. Features: • Measurements from pure water all the way to concentrated solutions with proven four electrode technology – now also wireless. • Proven 4 electrode technology • Easiest handling, robust design • No cables • WTW has been manufacturing conductivity measuring cells of the highest quality for decades. These are also the basis for the IDS conductivity measuring cells. • The advantages of the IDS technology include the automatic transfer of the cell constant and therefore the exclusion of possible erroneous input. • There are two models available to cover the entire conductivity range: The four electrode measuring cell TetraCon® 925 for medium and high conductivity , for pure water and for low conductivity, the two electrode measuring cell LR 925/01 including flow container. • WTW's proven IDS conductivity measuring cells are now available as sustainable plug head versions. The universal plug head fits the sensor with wireless functionality – disturbing cables are no longer required. • Furthermore it can be connected to AS/IDS-x cables with lengths of up to 100 m. With this new technology WTW significantly expands the range of applications and the measuring comfort of its digital conductivity measuring systems.
