"Help yourself to think on your feet in the field"

Reduce noise from quick-recovery tests
Capture sufficient data for short-duration tests
Manage initial displacements for high-K formations
Use your own pressure transducer
Apply to common well sizes up to 4 inches in diameter

This is the answer for accurate rising head tests when the water level is above the screen interval! The pneumatic slug uses air pressure from a hand-held pump to lower the water level and the easy-to-use valve releases the pressure immediately to dramatically improve test results!

Each pneumatic slug assembly comes with a pressure gauge reading head displacement in inches of water, a hand pump an attachment for a 2" diameter well, and a storage case. It is compatible with In-Situ and Solinist transducers up to 1" diameter. Optional accessories include attachments for fitting 3/4" diameter wells such as those for direct push well installations and attachments for 4" diameter wells.

Item# Hi-K SLUG™
Price: $345.00 ea.

Testimonials:
My company purchased the Midwest GeoSciences Pneumatic "Hi-K" Slug Test Assembly in early 2006 to use on a series of fractured, deep bedrock wells. The slug provided clean data during slug tests and allowed us to see oscillatory responses in some wells that were not observed using traditional slugs. For my office, it has become the primary method of slug testing when applicable.

The apparatus is well-built, fairly easy to install, and definitely a worthwhile addition one's field equipment inventory.

Equipment Update:
2010 version has a new type of washerless compression fitting to help ensure an air tight seal everytime. You can still use your own pressure transducer and data logger. Equipment update includes new manifold, new compression fitting with the ability to choose four cable diameters (fits most cable diameters).

Item# Hi-K SLUG™ UPDATE
Price: $89.00 ea.

English or Metric Measurements:
ONLY @ MIDWEST GEOSCIENCES GROUP! When you order a 2010 PNEUMATIC HI-K SLUG™, you can choose pressure gauge options that read in either English units (Inches of Water) or Metric units (Centimeters of Water). Design and measure your initial displacements that work best for you!
