UniTech has developed an automated laundry monitor (ALM) for every monitoring need. To meet our customers' demanding requirements, our ALMs have been engineered to ensure dependability while maximizing monitoring sensitivity. All systems utilize both upper and lower banks of gas-flow detectors and synchronized wire mesh conveyors which minimize detector-to-garment distance, resulting in optimum counting geometry.

Small Probe ALM
The ALM 100 uses 100 sq.cm. detectors arranged in two rows with the back row of detectors offset 50% from the front row. The small offset probe arrangement results in effective hot particle detection while minimizing false over-rejection. It is used for monitoring large items such as coveralls and hoods.

Alpha/Beta Monitors (ABM)
Our newest ALM is the ABALM-100/600 (Alpha/Beta Monitor) The ABALM uses 100 sq.cm. beta detectors and 600 sq. cm. alpha detectors in a double offset probe arrangement. This ensures there are no dead zones across the entire monitoring bed width.

Each detector has its own on-board amplifier to assure maximum efficiency. PC-based counting instrumentation simplifies operation and allows higher inspection rates for any required monitoring sensitivity. The general purpose monitor is used when alpha contamination is present. A beta-only version is also available.

Low Activity Monitors (LAM)
The LAM 410 uses 410 sq.cm. detectors in an offset probe arrangement. Digital instrumentation with individually amplified detector signals allow for monitoring to very low levels of activity, i.e. free release criteria. Typical usage includes personal items, inneralls, and radwaste segregation.
