About Us
Fifty years, one focus: measuring pressure right
From a street workshop to an exporter in 42 countries
QIAOQIAO began in Suzhou in 1974 making a single bourdon tube gauge. Fifty years later we still only do pressure and temperature measurement — but the range has grown to six series and more than 3000 variants.
Today we operate a 28,000 m² plant in Suzhou Industrial Park with 186 employees, 32 of them R&D and process engineers, producing 1.2 million instruments a year for customers in 42 countries across petrochemical, power, pharmaceutical, food & beverage, marine and semiconductor industries.
Three things we believe
Accuracy is the baseline. Every instrument is individually calibrated before shipment; records are kept for five years and available to customers at any time.
Life cycle is the real cost. We do not compete on price — we make the three-year cost of ownership lower, which is why our gauges last two to three years longer in corrosive service.
Selection matters more than the product. Medium, temperature, pressure and mounting — one wrong assumption defeats the best instrument. That is why half of our 32 engineers work on selection support.
