ND01 portable nuclear radiation detector Geiger counter dosimeter for X/β/γ rays 0-50000μSv/h

The ND01 radiation detector is a compact, pen-shaped Geiger counter designed for real-time measurement of X, beta (β), and gamma (γ) rays. This radiation detector is ideal for personal use in hospitals, laboratories, customs, seafood inspection, or everyday environmental monitoring. The device automatically subtracts 0.1µSv/h of natural background radiation for more accurate and reliable results.

Radiation detector - key features

• 3 Functions in One – Simultaneously measures X rays, beta (β), and gamma (γ) radiation, ensuring comprehensive control.
• Three modes of operation – REAL displays the instantaneous value, AVG calculates the average for more stable results, and ACC records the total accumulated dose.
• Three-level warnings – Audible and visual signals warn of a safe, warning, or danger zone based on the radiation level.
• Convenient features – Automatic shutdown (default 5 minutes, adjustable), battery charge indicator, and measurement unit conversion.
• Compact and Durable Housing – Pen-sized, lightweight, and easy to carry, making it convenient for outdoor use or travel.
• Clear Display – The LCD display with a status indicator ensures intuitive use without additional training.

It is recommended to regularly monitor the readings, especially when working with X-ray equipment or radioactive materials.

Buyer questions

Question: What types of radiation does the ND01 detect?
The device simultaneously measures X-rays, beta (β), and gamma (γ) radiation using an energy compensation GM tube. This allows for a comprehensive assessment of the radiation level in the environment.

Question: How does the warning system work?
The device has three alarm levels – safe, warning, and danger – which are activated by audible and visual signals depending on the µSv/h level in the environment.

Q: Are batteries included in the set?
No, batteries are not included. It is essential to purchase and insert two 1.5V AAA batteries before use to ensure the device functions properly.

The ND01 radiation detector is a reliable choice for those who require accurate and timely radiation measurements. Suitable for both professional and personal use at home, work, or during travel.
