This system consists of a light-tight detector assembly which is interfaced with the sample via male 1/8' pipe fittings with the readout and processor assembly via two BNC connectors.
The sample is passed through a filter and thence to the detector assembly where it is viewed by two pairs of matched photomultiplier tubes.
The tabletop or rack-mounted processor and display portion of this system conditions and analyzes the output from the photomultiplier tubes by pulse height and validated by a coincidence circuit thereby permitting the system to eliminate counting most background (noise) counts.
Meets CFR/NRC Regulation of 1.0 µCi/L (H-3)
NexTritium-H2O includes a unique statistical Significance Display.
- This function rates the strength of the data preventing most false positives or negatives:
- Significance: HIGH LOW or NOT SIGNIFICANT
