Pneumatic Measuring Instrument-QD-300

The Pneumatic measuring instrument is a high-performance device designed for precision measurement applications, developed specifically to meet the stringent requirements of industry and scientific research. The instrument has extremely high measurement accuracy, with a maximum resolution of 0.1μm, and no preheating is required when it is turned on, and it immediately enters an efficient working state. Whether it is the detection of the concentricity, roundness or other key parameters of the workpiece, the QD-300 series can provide accurate and reliable data support. It also has strong flexibility and can be equipped with any shape nozzle hole gas probe from 0.3mm to 2.0mm to meet the measurement needs of workpieces of different specifications. Its range selection function is flexible and diverse. Users can select ±5μm, ±10μm, ±25μm, ±50μm and other ranges through software to meet a variety of application scenarios. The instrument can also store up to 800 measurement data, which will not be lost when the power is off, and historical data can be queried and traced back at any time.
