OLINST CANADA LTD. has been manufacturing high quality groundwater instrumentation since 1980 when company president Doug Belshaw recognized the need for innovative and easy-to use instrumentation for the growing hydrogeology field.

First SOLINST introduced its Model 101 Water Level Meter for hydrogeologists . The sturdy design, stretch-resistant tape and special markings in feet and tenths of feet (now 1/100 ths) proved ideal. The Meter gained in popularity and soon became the Water Level Meter of choice for groundwater monitoring.

Since then hard work and determination has enabled SOLINST to offer a broad range of innovative and practical hydrogeological equipment. The SOLINST product line is ideal for site characterizations, spill investigations, and long-term ground water monitoring.
