- Biosafety cabinets (negative pressure monitoring)
- Medical equipment (ventilator pressure monitoring)
🔧 Installation Guide
- Connect the high-pressure end to the “+” port and the low-pressure end to the “-” port
- The installation position should avoid mechanical vibration
- Vertical installation is recommended (with the display screen facing up)
- Power on and preheat for 30 minutes before first use
- Perform zero calibration regularly (recommended once a month)
⚠️ Notes
- It is strictly prohibited to use beyond the range (＞84kPa)
- The medium temperature must not exceed 120℃
- Corrosive gases need to be equipped with an isolation membrane
- Avoid oil contamination of the measuring diaphragm
