Comparing Solinst Waterloo and CMT Multilevel Groundwater Monitoring Systems

The benefits of depth discrete monitoring have been known for years.

Which Solinst system will suit your application?

The Waterloo System (Since 1984)

Waterloo Systems have a modular design that gives excellent site and application flexibility, allowing placement of ports and packers to suit borehole logs. The engineered seals and dedicated sampling and level monitoring capabilities have been used to depths of 1000 ft (300 m). They are ideal for long-term monitoring in bedrock and cased boreholes.

The CMT System (Since 1999)

CMT Multilevel Systems offer in-field design flexibility, low cost and is easy to install. The number of monitoring ports, port locations, install depths, and monitoring strategy, can all be accommodated and designed right in the field. The single tube offers effective sealing. The 7-Channel System is 1.7″ (43 mm) and the 3-Channel is 1.1″ (28 mm). They are ideal for shallow applications in narrow diameter boreholes.
