GNW700 Precision Digital Pressure Gauge – 0.02% Accuracy
The GNW700 Precision Digital Pressure Gauge is a high-accuracy reference pressure indicator designed for calibration laboratories, test benches and high-precision industrial measurement. With an accuracy of ±0.02% of full scale, the GNW700 provides stable and repeatable pressure measurement across a wide range of industrial pressure applications.
The large backlit LCD display provides clear six-digit resolution and supports multiple pressure units, allowing the instrument to be used across different calibration and testing environments. Data can be transferred to a computer via the integrated RS232 interface for logging and analysis.
The GNW700 can be used as a reference pressure gauge when paired with pressure generation equipment such as comparator pumps or pressure controllers. This makes it suitable for calibration of pressure gauges, transmitters and sensors across multiple pressure ranges.
Supplied with a traceable calibration certificate as standard.
