Pressure gauge digital switch Measuring Range -100Kpa ~ 0 ~ 300Mpa Accuracy 0.5%FS Units Mpa, Kpa, bar, psi, kg/cm2

Pressure gauge digital switch

The VM281 Digital Pressure Gauge, using a special ASIC circuit and sensor design, no mechanical moving components, battery-powered, reading directly from the LCD display, thus it has a long life, easy to use, inexpensive, widely used on-site pressure indicator, such as pipeline networks, machinery and equipment and so on. In most cases, you can replace the pointer pressure gauge, this is upgrading new products. Two options, M281A (mainly used in high-pressure measurement display) and VM281B (mainly used in low and negative pressure measurements display)

The VM281 Digital pressure Gauge is widely used in the fields of Air conditioning and refrigeration, hydraulic machines, pneumatic equipment, pipeline network, powerhouse etc.
