Please select an application General purpose, aqueous pH measurements. Quality control, general laboratory and aquarium water Tris buffers, clinical, and biological media containing proteins, creams, fats and cosmetics Research measurements, fruit juices, beer, milk and yogurt High viscosity solutions such as emulsions, suspensions, paints and varnishes Non aqueous solutions. Must be used with special reference electrolyte EC-RE-015 Low temperature measurements Low ionic strength solutions, such as high purity water High temperature measurements Surface measurements such as paper, skin, textile, leather and agar plates Solid or semi-solid samples such as cheese, meats, fruits, bread, or other similar sample Rugged use; Ruggedized electrode tip. Aqueous media in general Portable pH meter; Field and school use Micro sample, such as semimicro cuvettes and NMR tube Test tube measurements Reference contamination problems which require a double junction reference Measurements in long, narrow vessels Soil pH measurements Swimming pool pH control under continuous flow conditions Isoelectric focusing gels and other surface measurements that require a small diameter flat tip Photographic chemical; high pH sample (12 to 14 pH) ORP measurements for general purpose Swimming pool ORP measurement ORP measurement for cyanide use ORP measurement requiring a double junction reference Hydrofluoric acid and abrasive solution measurements
