10.0 Monitoring Options

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 coaxial cable Model 102 Water Level Meter and 102M Mini Water Level Meter with a 0.157" (4 mm) diameter P4 Probe can be used to monitor water levels in open tubes. The coaxial cable is accurately laser marked every 1/100 ft or mm.


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 30ft (9m).


Model 408M 3/8” Dia. Micro Double Valve Pump

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 150mL/min make the 408M suitable for low flow sampling applications. Constructed of stainless steel and PTFE tubing for any depths up to 240 ft. (73 m) applications. This is the only viable option in wells with depth to water over 150 ft. (45 m).


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 150 ft. (45 m). If the water level on your site is deeper than 50 ft. (15 m), PTFE tubing is recommended.
