SSS-33M8 Series Tritium or Radon In-Water Monitor

Real Time Continuous

Model # SSS-33M8 – Tritium
Model # SSS-33M8R - Radon

SSS-33M8/M8R Tritium or Radon Water MonitorThis system consists of a small light tight detector assembly which is interfaced with the sample via 1/4 inch pipe fittings with the readout and processor assembly via two MHV connectors.The sample is passed through a deionize and filter and thence to the detector assembly, where it is viewed by a matched pair of
photo multiplier tubes. The table top or rack mounted processor and display portion of this system conditions and analyzes the output from the photo multiplier tubes by pulse height and coincidence, thereby permitting the system to eliminate counting most background (noise) counts.
* SSS-33M8 users, see ``Deionizer and Filter'' specification (SSS-33M8/D and SSS-33M8/F).
