PG 20 | Electronet

Product Description

PG-20 Digital Pressure Gauge is a reliable and cost-effective solution for accurate pressure measurement and monitoring in industrial and laboratory applications. It uses a piezo-resistive pressure sensor and supports a wide measuring range from 0.1 bar up to 1000 bar. Pressure indication is provided through a clear LCD display with auto display shut-off, helping to extend battery life. The gauge is battery-operated with optional solar power, ensuring long-lasting, maintenance-free operation. Built-in features such as unit conversion, zero tare, temperature compensation, and display lock enhance usability and accuracy. With IP-65 weatherproof enclosure, optional RS-485 MODBUS, GSM, or GPRS communication, and robust SS / die-cast housing, the PG-20 is ideal for demanding industrial environments.
