Monitoring Options

Water levels and samples can be accurately obtained using the following quality Solinst instruments:



Water Level Measurement:

solinst model 102 laser marked water level indicator

Model 102 Water Level Meter

The narrow, laser marked 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 any CMT channel. It is narrow enough to be used along side a pump in the same channel.


Well Completion:

solinst model 103 tag line
Model 103 Tag Line

The Tag Line is ideal to aid accurate placement of sand and bentonite during borehole completion.

The durable cable is laser marked every 1/4 foot or 5 cm.


Sampling Methods:

Depending on the depth to water at your site, and your sampling protocol, Solinst offers various sampling options.

solinst model 410 peristaltic pump
Model 410 Peristaltic Pump

Ideal for sample retrieval from shallow water levels less than 30 ft. (9m).


solinst mini inertial pump
Mini Inertial Pump 1/4" (6mm)

Sampling can be performed using the Solinst Peristaltic Pump, which has a suction lift limit of approximately 7.5 m (25 ft). The Mini Inertial Pump can be used with inexpensive polyethylene tubing to depths of 15 m (50 ft), or using PTFE tubing to depths of 45 m (150 ft).


solinst model 408m micro double valve pump
Model 408M DVP (3/8" Dia). Micro Double Valve Pump

The Micro Double Valve Pump (DVP) is ideal for low flow VOC sampling in narrow applications. The Micro DVP is made of flexible PFAS-free PTFE or polyethylene tubing which is 3/8" (9.5 mm) in diameter. A manifold at the surface has a quick-connect fitting for attachment to the Solinst Electronic Control Unit and a bypass for easy sample collection. Operation is easy, as the Electronic Control Unit has built in pre-sets. A multi-purge manifold is also available for the Micro DVP, for depths up to 73 m (240 ft).


solinst multi purge manifold
Multi-Purge Manifold

A multi-purge manifold can be considered for purging multiple CMT channels simultaneously using Micro Double Valve Pumps in each channel


solinst model 464 electronic pump control unit
Model 464 Electronic Pump Control Unit

Durable and easy to operate with the 408M by using built-in presets, or customized saved settings.


Vapor Samples:

solinst model 403 cmt multilevel system vapor monitoring wellhead seal assembly
Model 403 Vapor Monitoring & Wellhead Seal Assembly

Channel seal assemblies are availabe to seal the CMT channels in case of flowing artesian conditions, or vapor monitoring. If desired, a 3-way valve can be attached to the seal assembly directing vapor to a pressure gauge connected at one end of the valve and a sample vessel at the other.
