Water levels and samples can be accurately obtained using the following quality Solinst instruments:
| |
|
Water Levels: |
Model 102
Water Level Meter
|
The narrow coaxial cable Model 102 Water Level Meter and 102M Mini Water Level Meter with a 1/4" (6.3 m) dia. probe can be used to monitor water levels in any CMT channel. The coaxial cable is accurately laser marked every 1/100 ft or mm. |

|
|
Samples: |
Model 410
Peristaltic Pump
|
Groundwater sampling can be performed using the Solinst Peristaltic Pump, which has a suction lift limit of approximately 25 ft (7.5 m). |
| |
Mini Inertial Pump
1/4" (6mm)
|
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). |
| |
Model 408M DVP
3/8" (9.5 mm)
|
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. |
| |
Model 466
Electronic Control
|
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: |
Model 403
Vapor Wellhead
|
A special Vapor Wellhead Assembly can be used to obtain depth discrete vapor samples. |
