Coliy Group was founded in 1995, located in Dusseldorf , Germany with manufacturing facilities in German and Asia. In 1996, Coliy produced the first high performance microwave moisture analyzer. Coliy is the pioneer in the development of new generation of moisture analyzers and environment protection instruments, the products have excellent performance and quality characteristics. In 2005, Coliy Group produced a new generation microwave moisture analyzer, online non-touching microwave moisture analyzer, using a new advanced processing chip, with an operational speed 5 times faster than previous models. With the advent of the new century, Coliy Group accelerated product development and produced new automation products continually. Our product category is primarily confined to three types: moisture content analyzers, liquid level and pressure switches, and hand-held environment protection instruments. 
900 multi-function digital radiation meter of two kinds: ordinary type 900 and Enhanced 900 + Standard 900: Ray type selection switch, the instantaneous value of the radiation, the radiation accumulated value, the instantaneous value of the pulse, the pulse accumulated value. Enhanced 900 +: In the ordinary type based on the increase: overrun audible alarm, Chinese computer analysis software (optional English, German, Italian), remote real-time data display and analysis, manual and automatic recording, maximum hold .
