Solinst continuously measures and logs water level fluctuations, temperature and conductivity, making it an ideal tool for providing an indication of water quality. It is easily programmed to record at intervals as often as 2 seconds. The Levelogger 5 LTC includes an 8-year battery, memory for 100,000 sets of readings, and comes in 6 pressure ranges. A PFAS-free coating baked on using polymerization technology (inside and out) provides superior corrosion and abrasion resistance. The 4-electrode platinum conductivity sensor has a wide calibrated conductivity range, with autoranging from 0 to 100,000 µS/cm. For highest accuracy, calibration is from 50 to 80,000 µS/cm. ....
