The ESP PLUS pulls a 3 (or 4) foot long by 1.2 inch diameter sample in one plunge. It captures every sample in a plastic liner and can sample to 3 (or 4) feet. Sampling tube is driven by a 12.5 pound drop-hammer (or electric hammer) and retrieved with a foot-operated jack.
The JMC Environmental Fate Sampler takes a 6 inch diameter by 2 inch deep sample. It maximizes recovery of surface applied chemicals on day zero and greatly reduces surface contamination risk to subsequent samples. The Deluxe system adds components to reduce processing time.
