high precision digital pressure gauge MT-P300DG

Description

1. Introduction to the High Precision Digital Pressure Gauge MT-P300DG

The high precision digital pressure gauge MT-P300DG is a next-generation pressure measuring device designed for environments that demand superior accuracy, robust durability, and versatile display features. Unlike conventional pointer gauges or standard digital gauges, this instrument integrates an advanced high-resolution microprocessor, multi-unit pressure conversion capability, and dual-screen display technology for both real-time measurements and reference data display. With a stainless steel SS304 housing and a large 150 mm diameter body, the MT-P300DG is engineered for industrial reliability while remaining portable and easy to operate.

This pressure gauge supports 10 selectable pressure units, allowing users to adapt to international standards, laboratory conventions, and industry-specific measurement formats. The gauge also offers preset minimum and maximum pressure values, real-time site temperature display, dual power supply support (USB external power + battery), and exceptional low-power design capable of operating up to 3600 hours continuously on AA batteries.

Whether used as a reference standard in laboratory calibration setups, for on-site verification of pressure instruments, or integrated within industrial automation systems, the MT-P300DG ensures consistently accurate performance with stable long-term operation.
