High-sensitivity sensor
Computer data analysis software
Capable of detecting α, β, γ, and Χ rays
Large-screen high-definition LCD display
FJ-COMO60 multi-functional digital nuclear radiation instrument. It adopts a 2-inch large flat spiral sensor manufactured by the US Standards Bureau. It has high sensitivity and can quickly detect the intensity of α, β, γ, and Χ rays. It has a correction factor function, allowing customers to adjust the correction parameters themselves; it provides an average time setting function, significantly improving the sensitivity of the response. The FJ-COMO60 digital nuclear radiation instrument conforms to ergonomics, has an anti-saturation circuit to avoid electromagnetic wave interference, has a safety calibration function to avoid radiation exposure for calibration personnel. The product has the European CE certification standard and ISO9001 quality certification.
