For measuring the depth of water in wells, boreholes, and standpipes, the Model 101 Water Level Meter is the most accurate and reliable meter. It is sturdy, easy-to-repair and read to 1/100 ft. or to each millimeter.
Also available, from Solinst, are the less expensive laser marked Model 102 Coaxial Cable Water Level Meter for use in small diameter tubes, and the 102M Mini laser marked Water Level Meter in lengths of 80 ft. and 25 m. (See Model 102 Data Sheet).
Solinst Model 102 Laser Marked Water Level Meters have permanent, accurate laser etched markings every 1/100 ft or each millimeter. Providing Solinst quality at a low price, they have probes for use in wells as small as 3/8" (10 mm) in diameter, and a durable, flexible coaxial cable mounted on a sturdy reel. A 102M Mini Laser Marked Water Level Meter is also available, in 80 ft or 25 m lengths on a small lightweight reel.
Meters are powered by easy-access 9V batteries, have an excellent brake, convenient carry handle, and on/off sensitivity switch. Rugged design and Solinst reel make these meters ideal for field use.
A Solinst TLC provides accurate, stable temperature and conductivity measurements displayed on a convenient rotating LCD display. Water level measurements are taken from permanently marked flat-tape, every 1/100ft (or mm) up to 300ft. (100 m). Tape is flexible and hangs straight in application. Meter is ideal for temperature and conductivity profiling in wells or open water, and for a general indication of chemical contamination levels, salt water intrusion and salinity.
