4 Inch100MM Handheld Precision Digital Pressure Gauge

• Product Description

4 Inch100MM Handheld Precision Digital Pressure Gauge

Digital pressure gauges include precision digital pressure gauges, handheld precision digital pressure gauges, diaphragm digital pressure gauges, benchtop precision digital pressure gauges, and failure-proof digital pressure gauges.

Precision digital pressure gauges not only solve the problem of standard pressure calibration but also better meet the comprehensive testing needs in the field. They can be used as high-accuracy calibration standards (gauges) for the calibration and verification of pressure transmitters. These portable instruments can operate on both AC and DC power, measuring current simultaneously with pressure and displaying the results on an LCD screen, and also have a 24VDC output. A microprocessor automatically compensates for zero-point drift, temperature drift, and nonlinearity, ensuring high accuracy within the instrument's operating conditions. Single-range, single-function precision digital pressure gauges can replace traditional precision pointer pressure gauges.

Product Advantages

1. This precision digital pressure gauge is a portable instrument that can operate on both AC and DC power.

2. The high-performance microprocessor continuously corrects the instrument's performance and technical specifications, ensuring consistent accuracy over extended periods and across a wide temperature range.

3. Low power consumption. It uses imported high-energy nickel-metal hydride batteries, guaranteeing long-term operation.

4. Constant current charging with overcharge and undervoltage automatic shutdown and protection functions prevent battery damage due to overcharging or undervoltage, extending battery life.

5. Low-power undervoltage automatic protection ensures the battery will not be damaged by undervoltage even if the instrument is left on for extended periods due to operator error.

6. The instrument offers a wide range of measuring functions, providing multiple uses in one instrument.

7. The software is feature-rich, simple, and intuitive to use.

8. It uses a membrane panel touch switch with a novel design and long button life.

9. Full-scale calibration can be performed directly on the panel.
