Company Introduction
Yantai dongrun Instrument Co., Ltd. founded in 1998. It specializes in manufacturing online water quality analysis equipment, level meters, pressure gauges, flow meters, special temperature gauges and laboratory analysis equipment. Our company cooperates with Chinese Academy of Sciences and builds up a water analysis laboratory, mainly producing TOC analyzer, ammonia analyzer, fluorescence oxygen analyzer, etc. We have passed the ISO9001 certification. Our professional R & D team can provide technical supports to satisfy customer demand and our unique technologies can meet different working conditions.
Product Introduction
It can be used to measure level of various vessels in the shape of tower, kettle, groove and ball as well as boiler furnace. It can be used in complex conditions, such as highsealing, leak prevention, high pressure, high temperature and corrosion. In the measurement process, no measurement blind area. It strikingly displays the level and has a wide measurement range. Compared with traditional glass plate level gauge, it is safer, more reliable, more advanced and more practical. The most obvious characteristic is the complete isolation of liquid medium and indicator so it can be used safely, reliably and durably in any case.
