Please email for lead time
Item Number: EQ-RD-15-LD

EQ-RD-15-LD is a portable, high accuracy digital Geiger Counter / Dosimeter for monitoring the immediate radiation level and accumulated dose of X-ray radiation. It provides easy and quick radiation measurements, such as immediate radiation level of an active X-ray instrument, accumulated dose around the X-ray instrument or on the user, and background radiation monitoring. Both vibration alarm and audio alarm can be set to warn the user of a specific radiation level. The dosimeter also detects Beta and Gamma radiation.  



  • Measure both the immediate radiation level and the accumulated dose
  • Highly accurate sensor tested by the Japanese Consumer Protection Agency. Certified in Germany. Pre-calibrated
  • Scale range of 0.05~9.99 µSv/h (micro Sieverts per hour) or 5 ~ 99.9 µRem/h
  • Both vibration and audio alarms can be set to warn the user of a radiation level ranging from 0.10 to 0.90 µSv/h (adjustable)
  • Combined X-ray, Beta, Gamma radiation detection

 Power Supply / Power

  • Two AAA size batteries on the back of the unit

 Detection Range

  • 0.05~9.99 µSv/h
  • Or 5 ~ 99.9 µRem/h

 Detection Time

  • Low radiation level: ~40 seconds cycle to ensure accurate reading
  • High radiation level: immediate

 Alarm Threshold

  • Threshold level: 0.10 to 0.90 µSv/h with 0.10 µSv/h interval
  • Alarm: both vibration alarm and audio alarm can be set

 Background Radiation

  • Background radiation is measured and displayed to show the difference with current level


  • DIN IEC (International Electrotechnical Commission) 60846-1 Certificate
  • EN 61326-1 Certificate


  • 60 mm L x 25 mm W x 105 mm H


  • 3 oz (85 g)

 Application Example

  • The dosimeter is used to check the radiation level of MTI's X-ray instruments
  • The radiation level is measured as 0.07 uSv/h, which is the same as the background level, indicating good radiation protection from the unit
           Safe level outside EQ-DX-100G     Safe level outside EQ-MD-10-LD

 Application Note
