Our Product Line Features

Simple user interface minimizes setup time.
Compact modules that screw directly onto HN connectors used with many gas-filled detectors.
Engineered for stable, reliable operation in difficult microphonic, humidity and temperature environments.
TTL output interfaces directly to pulse counting electronics.
TTL input allows digital pulse summing.
Trimpots provide user control of preamplifier sensitivity (Threshold) and the pulse width of the TTL output pulse.
Test point allows monitoring of amplified neutron signal.
An LED flashes with detected events, providing visual indication of detected events.
An internal trimpot (HV ADJ) or an external DC voltage (0-2.2 volts) controls the PDT100A high voltage bias supply.
Power supply input configurable for either +5 volts or +12 volts.
An aluminum enclosure ensures a low noise system and minimizes EMI interference and grounding problems.
All modules are engineered for high radiation environments (tested in excess of 1Mrad integrated dose without failure).
