Solinst 114620 Levelogger 5 LTC water level, conductivity & temperature logger, 200m range

The Levelogger 5 LTC logs water level, temperature, and conductivity. It combines a datalogger, 8-year battery, Hastelloy pressure sensor, temperature detector, and conductivity sensor within a small waterproof housing, 22mm x 208mm (7/8" x 8.2"). A baked-on coating using polymerization technology protects the body against corrosion, abrasion and high temperatures. The conductivity sensor is a 4-electrode platinum sensor, with autoranging capabilities. The minimal-maintenance, sealed Levelogger 5 LTC is simple to clean and calibrate, even in the field.
