The Thermo AMS-4 Beta Particulate Air Monitor is a designed for the detection and measurement of airborne
beta emitters. This listing is the main processing unit. A sampling head and integrated pump is available as an option.
The main processing unit acts as the central element which monitors all inputs and controls all outputs. Three serial ports support communications with the sampling head, printer, and host computer. In addition, the main processing unit provides a keyboard, display, and status lights.
An AMS-4 can be equipped with either a radial entry or an in-line sampling head depending on the user selected configuration. Both the radial inlet and in-line sampling heads have two microcomputer boards. These boards gather radiological counts from a beta/alpha sensitive detector and a gamma sensitive background detector. One of the boards also measures air flow volume. This information is then processed and sent by RS-485 serial communications to the main processing unit. The detector boards also annunciate the alarm horn and lights on the sampling head and monitor the alarm acknowledge and filter door switches.
Width with radial or gas head attached = 16.4 in. (41.6 cm)
Width with radial or gas head detached = 11.0 in. (27.9 cm)
Depth = 7.3 in. (18.5 cm)
Height without integrated pump = 12.8 in. (32.5 cm)
We usually have sampling heads for this detector in stock.
