GM Probes

The Model HP-210 series hand probes

provide a sensitive beta detector fea-

turing a "Pancake" GM tube with a

thin mica window. This series is

designed for contamination surveys

on personnel, table tops, floors,

equipment, etc. These probes can be

matched with Thermo's portable sur-

vey meters, such as the ASP-2, E-600,

RM-25, Surveyor or Electra/Delta

series.

This is an excellent general purpose

GM probe, with energy compensation

and a beta shield, making it the choice

for most health physics applications.

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. See

also the SWGM.

A gamma hand

probe that uses

a small halo-

gen-quenched

GM tube for

detection of rel-

atively high range

gamma fields. The Geiger

tube assembly is easily removable

from the shield. Used for gamma sur-

veys in high backgrounds and direc-

tional indications. This probe can be

matched with Thermo's portable sur-

vey meters, such as the ASP-2, E-600,

RM-25, Surveyor or Electra/Delta

series.

• Operating voltage: 600 V ±50V

• Detector range: 300 R/h (with Dead

time correction)

• Front to back shield ratio ² 9:1

• Operating temp: -30 ºC to 60 ºC

(-22 ºF to 140 ºF)

• Housing: Steel, chrome plated

• Connector: BNC
