If you have two technicians in the field or need to switch probes before you take smaller diameter samples, it may be expedient to plant several 2 inch diameter casings in the ground before returning to sample through each casing. That is why we sell separate casings for the JMC 2 by 6 inch Concentric Sampling Tube.

• Fits the PN400 JMC 2 by 6 inch Concentric Sampling Tube
• Easily planted and retrieved by any JMC probe fitted with the PN400
• Nickel-plated steel construction

Remember: This is the casing only. You should already have a Concentric Sampling Tube.
