Portable Ion Chamber Survey Meter


lead time: usually 4-8 weeks

This auto-ranging portable ion chamber survey meter is battery powered, making it ideal for use in nuclear medicine, radiotherapy and radiography departments, as well as nuclear energy facilities. This portable ion chamber survey meter is capable of accurate and highly stable measurement of dose rates and integrated dose of beta, gamma and x-ray radiation.

This portable ion chamber survey meter is an ideal radiation measurement tool for the NDT community due to it's capability of measuring x-ray bursts from 5 picoseconds.

  • - Portable
  • - Highly stable
  • - Measure 60 nanosecond x-ray bursts
