Solution Overview

• Conventional aneroid barometers(800 hPa ~ 1060 hPa)

• Plateau aneroid barometers(500 hPa ~ 1060 hPa or 500 hPa ~ 1030 hPa)

• Aneroid barographs(870 hPa ~ 1050 hPa)

Solution Features

• AC/DC poweredfor negative pressure (vacuum) generation

• Built-in rechargeable lithium batterywith 16,800 mAh capacity — over one week of continuous operation on a single charge

• CID control:Layered micro-touch switch — internal high pressure automatically triggers CID to activate pressurization, with explosion-proof protection

• PTC control:In the event of overcurrent or short circuit, temperature rises sharply, PTC resistance increases, cutting off the current and stopping output

• PME control:When temperature exceeds 160°C, PME micropores close, physically isolating and stopping current flow

• Five-fold protectionon the current control board: overcurrent protection, short-circuit protection, low-voltage protection, overcharge protection, and temperature control

• Automatic pressure generationwith a range of 500 hPa ~ 1200 hPa

• External precision digital pressure gaugefor convenient calibration submission; pressure type: absolute pressure; range: (0 ~ 120) kPa.a; accuracy: 0.02%

• Aneroid barometer verification chamber dimensions:160 × 125 mm (customizable)

• Power source:Built-in electric pump with pressure regulation; power supply: DC 12V, 100W or AC 220V

• Output ports:2 × M20×1.5 female-thread output ports; weight: 5 kg
