VOLTCRAFT PR-80 Differential Pressure Meter ±0.137 bar, 11 Units, Backlit LCD, Data Hold, Min/Max/Avg, Air & Non-Corrosive Gases VC-13101370

The VOLTCRAFT PR-80 stands apart from ordinary manometers by combining laboratory-grade differential pressure measurement with field-ready ruggedness. Its ±0.3% full-scale accuracy and 0.001 bar resolution let you quantify pressure drops across filters, verify cleanroom pressure cascades, or balance HVAC ducts with confidence—all from a single handheld device that reads 11 different pressure units.

Highlights

• Measures differential pressure from ±0.137 bar (±137 mbar) with selectable units: psi, inH2O, bar, mbar, kPa, inHg, mmHg, ozin², ftH2O, cmH2O, kgcm²
• High accuracy of ±0.3% F.S. at 25 °C and fine resolution down to 0.001 bar (unit dependent)
• Backlit LCD with Min/Max/Avg recording, Data Hold, and one-touch zero adjustment
• Auto power off after 20 minutes (can be disabled) and 10 bar overload protection
• Supplied with two 4 mm connection hoses, 9 V battery, carrying case, and user manual

In daily use

Connect the two silicone hoses to the high and low pressure ports and the PR-80 instantly displays the differential. The backlit screen remains readable in dim mechanical rooms, while the Min/Max/Avg function captures fluctuating pressures over time. For long-term monitoring, disable auto power off and let the meter log for up to 100 hours on a single 9 V block battery. The robust housing tolerates temperatures from 0 to 50 °C and humidity up to 80% RH, making it suitable for both bench and field work.
