  • The ECC Model 890 Dose Meter / Exposure Time Meter is specifically designed to measure x-ray dose. The instrument is used to measure the effective dose produced by diagnostic x-ray generators. The ECC Model 890 is a solid-state, digital instrument designed specifically for service personnel in assessing the performance of radiation generators and the effective dose delivered by the x-ray generator under specific test conditions. This instrument measures the amount of x-ray radiation delivered to a specific area and measures the length of an exposure. The Model 890 can be used for dental x-ray units, radiographic and fluoroscopic x-rays.

    The Model 890 automatically resets at the beginning of each exposure, holding the reading until the next exposure. There is no need to reset the meter before each measurement.

    The Model 890 is a small hand held battery operated unit. Each x-ray exposure is displayed on a 2x12 digit liquid crystal display (LCD). The operator can select between English (mR) and SI (uGy) units.

    Radiation is detected by a solid state detector and electronic circuit. The instrument works for half-wave, full-wave, multiphase or DC (constant potential) x-ray generators. When a measurement is being made, the Model 890 has the capability of automatically determining the type of x-ray that is being measured. It is not necessary for the user to program correction factors for different types of x-ray waveforms.

    Typical Applications
  • Measure effective dose.
  • Test mA and mAs linearity.
