SS300 : Pancake Geiger for contamination measurements. An uncompensated pancake (550V) Geiger based probe for beta and gamma contamination measurement.

SS315 : Pancake Geiger for contamination measurements. Functionally identical to the SS300, but with a different probe geometry.

SS330 : Compensated pancake Geiger for dose rate measurement. An excellent general purpose GM probe with H*(10) energy compensation, which permits reliable measurements from ambient background up to 1 mSv/hr

SS335 : Compensated pancake Geiger for dose rate measurement. Functionally identical to the SS330, but with a different probe geometry.

SS340 : Side window Geiger probe for ambient gamma radiation measurement, to H*(10). Range: 0 - 2 mSv/hr - Energy: 45 keV - 2 MeV
