Fluke Model ASM-992 Victoreen Advanced Survey Meter with probe 489-110D

Description

The ASM-990 is a portable, battery operated general-purpose survey meter for use with all Victoreen Geiger-Mueller (GM) and scintillation probes, proportional counting probes and neutron probes. The ASM-992 is identical to the ASM-990 with the addition of a second, internal GM tube and supporting circuitry.
The ASM-990 series can detect alpha, beta, gamma, or x-ray radiation. The fast response and high sensitivity of the Geiger-Mueller tube makes it great as contamination monitor or as a general survey meter. S
urvey Mode feature allows user to store up to 5 separate survey sequences. Includes
Infrared Data (IrDA) port.
Operating modes:
Rate,
