water balance

water balance Brief Introduction. the OUM-intelligent III near-Infrared basis-weight water balance(LED display,touch- liquid crystal display shows the measuring result of vertical curve and horizontal curve and these result can be stored.) Main Features: 1.The Near- Infrared measurement has neither radioactive pollution nor toxic side effects to enviroment and human body, leaving out all kinds of elaborate formalities for isotopes quantometer and saving the high fees of conserve for the half-life radioactive source 2.Adopting one sensor to detect basis-weight and moisture simultaneously,which realize the fast and accurate measurement with low cost. 3.with the advanced semiconductor refrigerating technique controls the sensor temperature,the instrument can assure the stability measurement and it equiped no cold-water equipment. 4.The precise automatic adjustment error technique saves frequent sampling and makes the operation more easily. 5.The instrument furnished the standard RS485 and 4 20mA output interface and can link with other equipment. 6.the instrument can work under terrible environment and its operation voltage can be adjusted in very wide range.
