Water levels and samples can be accurately obtained using the following high quality Solinst instruments:
Water Level Measurement - Model 102 Water Level Indicator
The narrow cable Model 102 Water Level Meter and 102M Mini Water Level Meter with a 4 mm (0.157") diameter P4 Probe can be used to monitor water levels in open tubes. The coaxial cable is accurately laser marked every mm or 1/100 ft.
Well Completion - Model 103 Tag Line
The Tag Line is ideal to aid accurate placement of sand and bentonite during borehole completion.
Sampling Methods
Depending on your site’s depth to water and your sampling protocol, Solinst offers various sampling options.
Model 410 Peristaltic Pump
Ideal for sample retrieval from shallow water levels less than 9 m (30 ft.).
Model 408M 3/8” Dia. Micro Double Valve Pump
The Small and flexible design makes this gas drive pump ideal for delivering high quality samples, in combination with the Model 464 Electronic Control Unit. Flow rates of 20 to 150 mL/min make the 408M suitable for low flow sampling applications. Constructed of stainless steel and PTFE tubing for any depths up to 73 m (240 ft.) applications. This is the only viable option in wells with depth to water over 45m (150 ft.).
Model 464 Electronic Control Unit
Durable & easy to operate with the 408M by using the presets and fine tuning capabilities built into the Solinst Model 464 Electronic Pump Control Unit.
Mini Inertial Pump
This Mechanical pump uses 1/4" LDPE tubing. Typical flow rates of 50 to 250 ml/min. Suitable for use to depths of approximately 45 m (150 ft.). If the water level on your site is deeper than 15 m (50 ft), PTFE tubing is recommended.
