使用场景 APPLICATIONS

1 HVAC system maintenance: Measuring air flow velocity and differential pressure in ventilation ducts, filters, or air handling units

2 Industrial process monitoring: Checking differential pressure in non-corrosive gas pipelines and tightness of sealed systems

3 Building facility inspection: Testing pressure and flow in heating, ventilation, and air conditioning systems

4 Laboratory experiments: Precise differential pressure measurement for non-corrosive gas-related tests

5 On-site field measurements: Portable design allows easy use in various on-site scenarios, with optional data printing (requires compatible printer accessory)

注意事项 PRECAUTIONS

1 Measuring medium restriction: Only applicable for non-corrosive gases; do not use with corrosive substances

2 Environmental conditions: Operating temperature range is0-+60℃; storage temperature range is-10-+70℃; avoid extreme temperatures

3 Battery management: Use9V block battery (6F22); replace when low; auto-off activates after10min to save power

4 Accessory care: Do not overload the silicone hose (05540440) beyond700hPa; keep pilot tube (06352145) clean and unblocked

5 Protection: If using optional TotSafe case, ensure proper fitting to protect the instrument

6 Calibration: Regular calibration is recommended to maintain measurement accuracy
