Enhanced Penumbra Without Signal Compromise

SNC125c is a waterproof, fully-guarded, thimble ionization chamber with a design that reduces the convolution of high-dose gradient regions during profile and depth measurements. It is intended for use in scanning, field, and reference dosimetry measurements.

Features & Benefits

  • Enhanced penumbra without loss of signal strength
  • Easier set up
    • The seam on the chamber body between black and white indicates correct set up of the detector in relation to the detector holder1
    • The white chamber body gives a clear line of sight to the crosshairs and lasers during set up and set up verification
  • True measurement
    • Using a smaller inner diameter size results in a truer measurement of high dose gradients
  • Meets IEC 60731 standards for reference class dosimeters
  • No need for secondary water-proofing
  • Triaxial BNC and TNC type connectors available
