3001 Levelogger 5, M100

The Model 3001 Levelogger® 5 provides absolute precision when automatically recording changes in water level (pressure) and temperature. It is a self-contained (non-vented) datalogger, that uses a superior, corrosion-resistant, Hastelloy® pressure sensor with an accuracy of ±0.05% FS.The Hastelloy sensor has great performance and response times in extreme temperature and pressure environments. It can withstand 2 times over-pressure without permanent damage. The Levelogger 5 comes in different pressure ranges to suit expected water level fluctuations, from 5 m to 200 m (15 ft. to 600 ft.).The sealed unit contains a temperature sensor that gives accurate readings (±0.05ºC) and provides temperature compensated water level values. The Levelogger 5 has a lithium battery that lasts 10 years based on 1 reading every minute. The internal datalogger has memory for 150,000 level and temperature readings.For use in seawater, and for extra corrosion, abrasion and chemical resistance, the 22 mm x 1
