Nuclear Radiation Detector Radiation Detection Device for Industrial Safety Monitoring and Environmental Radiation Assessment

Price Negotiable
Price: Negotiable
MOQ: 1
Delivery Time: 5-8
Brand: Airppb
Product Description
Product Name: Portable Radiation Monitor and gamma counter

Model: MR-NUI500

The PR-PMD100 Portable Survey Meter is a portable personal gamma survey device independently designed and manufactured by our company. This device incorporates both scintillator and semiconductor dual detectors, featuring the dual advantages of high sensitivity and wide measurement range. It is primarily used for gamma radiation dose measurement in applications such as radioactive medicine, industrial non-destructive testing, radioisotope applications, occupational disease prevention, security applications, nuclear power plants, and areas surrounding radioactive workplaces.

Product Features


  • Wide-range dose measurement: 0.01 μSv/h - 1 Sv/h
  • High sensitivity: ≥400 cps/(μSv/h)
  • Three measurement modes: dose rate, count rate, and cumulative dose
  • Configurable high and low dose rate alarm thresholds, continuously adjustable
  • Three alarm modes: audible, visual, and vibration
  • Compact and portable design: weight 280 g; dimensions (mm): 104 × 70 × 34
  • Intrinsic error: <5% (within 100 μSv/h - 1 Sv/h range)
  • Energy response: 50 keV - 3 MeV, <±20% (for ¹³⁷Cs)
  • Ultra-fast response: when exceeding background by 0.1 μSv/h, alarm time <1 s
