Light Weight Center Rods

imageThese light weight center rods help eliminate operator fatigue and are easier to use (because of the weight) when working with Geoprobe® dual tube samplers and the Macro-Core® Center Rod system. The deeper the sampling event, the more benefit from the reduced weight. Geoprobe® Light-Weight Center Rods were designed for use with the DT22, DT325, and MC5 Center Rod Sampling Systems only. Each 48-in., 1.25 in. OD Center Rod weighs 4.4 lb. (2 kg). Light-weight center rods are also available in 60-in. lengths that weigh 4.86 lb. (2.2 kg) each.  The deeper the sampling event, the more benefit from the reduced weight. There's also less weight to carry on the probe machines.

“Using the Geoprobe® light-weight center rods, I was able to dual tube (DT21) 300 feet per day on average, and on one occasion, 500 feet in one day.” - Rob Mores • Enviro Dynamics LLC • Hebron, IN
