LM 211S

Off-line Gamma Liquid Monitor

The LM 211S from the RAMSYS product line has

been developed to sample liquid from a pipe, a tank

or a pool. A 1¼"x1" NaI scintillation detector face

a liquid sampler inside a 4 π lead shielding for the

gamma emitting isotope monitoring.

A radioactive source built into the NaI crystal allows

compensation of potential drift whenever temperature

changes occur.

The spectrometry capability, based on a 1024 chan-

nel spectrum analysis, allows immediate and easy

radio isotope identi cation in case of alarm.

APPLICATIONS

• Ef uent release monitoring

• Operational process monitoring

RELATED MONITORS

• LM 212S: version with 10 cm (4 in) lead shield

FEATURES

● Energy spectrum and temperature changes

compensation

● Available with or without display or local signaling

● Available under 10 CFR 50 App.B, ASME NQA-1 and

IEC61226 programs for safety related applications
