The Ermenrich Ping RD20 radiation meter is a compact and practical device for measuring background radiation in the environment, water, food, etc. It measures gamma, beta and X-ray radiation in the range of 0.05 µSv to 50 mSv.

Due to its miniature size and light weight, the instrument has the full functionality of a dosimeter with Geiger-Müller counter and can be operated for up to 50 hours with a single charge. Powered by a 150 mAh lithium battery, the LCD display shows the measured values and the state of charge of the battery.

Features:

• Measurement of gamma, beta and X-rays
• Geiger-Müller counter
• Compact housing, LCD display
• Up to 50 hours of continuous operation
• Beep and light alarms
• USB-C cable
