GM Probes

This is a higher range GM probe with

energy compensation, providing reli-

able exposure rate measurement.

Used for Beta/Gamma exposure sur-

veys. This probe can be matched with

Thermo's portable survey meters,

such as the ASP-2, E-600, RM-25,

Surveyor or Electra/Delta series.

This hand probe pro-

vides a sensitive beta

detector, featuring a

"Pancake" GM tube with

a thin mica window. It is

designed for contamina-

tion surveys on person-

nel, table tops, floors,

equipment, etc. This probe can be matched

with Thermo's portable survey meters, such

as the ASP-2, E-600, RM-25, Surveyor or

Electra/Delta series. Please also refer to the

ECPGM and PGM probes

The MC71 a sensitive, energy compen-

sated GM detector with a low intrinsic

background, used for low level sur-

veys. This probe can be matched with

Thermo's portable survey meters,

such as the ASP-2, E-600, RM-25,

Surveyor or Electra/Delta series.

The MINI 6-80 Environmental Gamma

Radiation Meter is a portable counting

system for the determination of low

level gamma radiations. It consists of

the high sensitivity, MC71 GM tube, 6-

80 Scaler Ratemeter, cable, mounting

tripod and carrying case. It is used

extensively by nuclear plants and

local authorities as a reliable means of

measuring environmental gamma lev-

els. The MINI 6-81 is a weatherproof

version.
