Dongguan Pioneer instrument co., LTD. is a company specializing in the production of pressure gauges, temperature and liquid level instrument manufacturers, factory with advanced production equipment and manufacturing process, and lead to domestic and foreign advanced management concept, to create the optimal product quality, beautiful appearance, and fast delivery, good service. PIONEER (Pyle resistance meter) enjoys a good reputation in the industry. The p-zn25 series endogenous digital display pressure gauge is fully electronic structure, with battery power and easy installation. Front high stability piezoresistive pressure sensor with high precision, the output signal by high precision, low temperature drift amplifier amplification processing, into the high accuracy A/D converter, convert the microprocessor can process digital signals, after processing, the LCD display shows the actual pressure value. This type of instrument is flexible, easy to operate, easy to debug, safe and reliable. It is widely used in water and electricity, water, petroleum, chemical industry, machinery, hydraulic and other industries, and the pressure of the fluid medium is measured.  Internal source digital display pressure gauge technical parameters: Model: P - ZN25AC - 060 - m Brand: PIONEER Table size: 66 mm Range: 0~6MPa (customized by request) Material: ABS shell, part copper alloy Installation method: radial Interface thread: 1/4pt (customizable, multi-threaded optional) Power supply voltage: 9VDC (basic) Accuracy rating: 0.25%F.S.  Features of internal digital display pressure gauge: Large screen LCD display, high resolution, ignore value error. Peak retention function to record the maximum pressure value in the measurement process. Pressure percentage dynamic display (progress bar display) Five kinds of engineering unit selection: psi, bar, kPa, kg/c ㎡ MPa Select 1~15min automatic shutdown function. Micro power consumption, can work for more than 2 years in power saving mode, continuous work 2000 hours. The parameter correction function, the spot can be fixed to the instrument zero, the error value is corrected. Sampling rate: 4 times/s Applicable to the pressure measurement of various gas liquids compatible with copper alloy.
