This NEW pocket size meter is lightweight, rugged, and inexpensive. The Model 2401-series pocket survey meters are enclosed in an aluminum housing for ruggedness, however they weigh less than a pound. There are four separate models to meet most applications:

Model 2401 -EC Pocket Survey Meter employs an internal energy compensated G-M detector for gamma radiation with a range of 0-200 mR/hr. Model 2401-EC2 has an internal energy compensated G-M detector with a range of 0-2000 mR/hr. Model 2401 -EW employs an end-window G-M for alpha, beta, and gamma detection. Model 2401-P Pocket Survey meter has a full size pancake G-M (2"dia.) for alpha, beta, and gamma detection.
