Digital Vacuum and Pressure Manometer with Backlight Display – GAOTek

Description Overview GAOTek Digital Vacuum and Pressure Manometer with Backlight Display is a high-precision device designed for accurate measurement of vacuum and pressure in various industrial and laboratory applications. This product features a clear digital LCD display with a dynamic bar graph, allowing users to read measurements intuitively. It supports multiple pressure units, including mmH2O, mmHg, psi, kPa, MPa, Pa, mbar, and bar, making it versatile for different measurement standards. This device is equipped with an imported high-performance sensor, providing superior stability, corrosion resistance, and impact resistance. The intelligent signal processing circuitry ensures ultra-low power consumption, and it is powered by a high-energy lithium battery with a lifespan of 2–3 years, or it can be used with rechargeable batteries.   Features Ultra-precise measurements up to 0.05% across a wide -0.1 to 260 MPa range. Supports multiple pressure units for versatile applications. Easy-to-read 5-digit digital LCD with analog bar graph. Durable, stable, and low-power design with long-lasting lithium or rechargeable batteries. Flexible data outputs including RS232, RS485, USB, 4–20 mA, and optional wireless monitoring.   Technical Specifications Measuring Range -0.1 to 260 MPa Accuracy Class 0.05%, 0.1%, 0.2%, 0.4% Display 5-digit dynamic digital LCD analog bar graph Pressure Units mmH2O, mmHg, psi, kPa, MPa, Pa, mbar, bar (up to ten units optional) Output Signals RS232, RS485, USB, 4 mA to 20 mA, optional wireless communication Overload Pressure Range 1.5–3 times the measuring range, depending on model Power Supply 3.6V high-energy lithium battery (2 to 3 years) or rechargeable Process Connection M20 × 1.5 (external thread), other connectors optional Mounting Radial direction mounting Material Stainless steel case Additional Features Micro-power operation, intelligent calibration, zeroing with magnetic induction pen, peak recording, dynamic curve display Medium Temperature -40 °F to 194 °F (-40 °C to 90 °C) Dimensions 9.84 in × 7.87 in × 3.94 in (25 cm × 20 cm × 10 cm) Weight 70.55 oz (2.0 kg)
