Geiger Counter NR-850 Nuclear Radiation β Y X-ray Detection

PRODUCT DESCRIPTION:

Pro quality NR-850 geiger counter / nuclear radiation detector (Blue model).

LCD display with automatic data storage.

Three alarm methods: sound, light & vibration.

Higher spec Geiger tube, with improved accuracy & stability.

Features:

With an easy to read LCD display, the working status of the instrument is clearly displayed & you can quickly & accurately read the data you need.

With the function of automatically storing data, even if the power is suddenly cut off, the data is secure & can be stored for a long time.

The NR-850 nuclear radiation detector is greatly improved over more basic models.

Specifications:

• Five measurement units: uSv/h, uGy/h, mR/h, cps, cpm.
• Detecting rays: X, Y, β (hard beta rays)
• Dose current rate: 0.01~1000usv/h (10msv/h)
• Cumulative dose equivalent: 0.01μSv~500.0mSv
• Energy response: 48KeV~1.5MeV≤±30% (for 137CS-)
• Sensitivity: 80CPM/uSv (for Co-60)
• Relative inherent error: NR-750≤±15%(137CS1mSv/h) – basic model, only reads uSv/h, uGy/h, mR/h
• NR-850≤±10%(137CS1mSv/h) – higher spec Geiger tube, accuracy and stability improved, professional model
