Model 403 CMT Multilevel System*

Model 403 CMT Multilevel System*

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

Water Levels:

The narrow coaxial cable Model 102 Water Level Meter with the 1/4" (6.4 mm) diameter probe is ideal for taking water level measurements in either CMT System.

Samples:

Groundwater sampling can be performed using the Solinst Peristaltic Pump, which has a suction lift limit of approximately 25 ft (7.5 m).

The Mini Inertial Pump can be used with inexpensive polyethylene tubing to depths of 50 ft. (15 m), or using Teflon® tubing to depths of 150 ft. (45 m).

The Micro Double Valve Pump (DVP) is ideal for low flow VOC sampling in narrow applications. The Micro DVP is made of flexible Teflon® 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.

Vapor Samples:

A special Vapor Wellhead Assembly can be used to obtain depth discrete vapor samples.
