GMP-10
GMP-10 is the world’s most sensitive radon instrument with energy-dissolving pulse chamber. It can be used in both field and laboratory. This can be achieve that thanks to its low weight, high sensitivity and fast response time together with an efficient pump and analysis.
With GMP-10 you get:
- Correct radon content with 10% error margin within 10 minutes.
- Ability to perform various measurements at 20 minutes intervals.
- A complete software for analyzing time distribution of radon content and its energy spectrum.
- An easily portable instrument with high memory and battery capacity.
- Store more than 500 sets of test data, each data includes date, number, time, temperature, humidity, air pressure, radon concentration, GPS and other data..
You can perform significantly more measurements with GMP-10 in one day compared to any other instruments on the market. GMP-10 also logs ambient temperature, humidity and GMP-10pheric pressure with its integrated sensors.
Common uses for GMP-10 are property inspection and follow-up measurements after action, but it is also a common reference instrument for calibration chambers.
