The Easy-Count unit is a field deployable smear counter for measurement of surface contamination. It is designed to be used with the Colibri or RDS-31/32 survey meters (specific model for each meter including dedicated holder and cable). The silicon PIPS detector with 17 cm2 detection area makes it an ideal tool for direct measurement of alpha and beta emitters. PIPS technology brings numerous benefits to a field deployable smear counter.

These benefits are:

  • An improved MDA (much lower gamma background compared to other technologies)
  • Very good alpha /beta discrimination
  • A durable entrance window (not pressure sensitive). It is also easy to clean!

The Easy-Count counter is an addition to the Canberra™ Smart Probe (CSP) family. It includes all key components of hardware circuitry (high voltage power supply, amplifier, discriminator, etc.). Also, the intelligence associated with controlling those components is located in the counter – including control and storage of key parameters, settings, calibrations, device ID, alarm settings (10 values for each unit to display with default setting), etc. Thus the counter is a fully integrated subsystem taking and transmitting the measurement to the instrument, which is used for display.

With high voltage and digitization of the data occurring in the counter, measurement quality is not dependent on external device quality (cable, host instrument). Moreover, a CSP uses a serial protocol to communicate with the host which can be an instrument or a PC.
