The gauge has backlight, auto off, low battery indication, overpressure alarm and other functions. It is designed for use in piping system, refrigerated system and other applications.

  1. Stable and Reliable Sensor: Use temperature-compensated pressure sensor, temperature drift not exceeding ±0.04%FS/℃
  2. LCD Screen& Blue Backlight Display: Partition display for different measurements, direct readings for all measurements.
  3. Various Refrigerants Options: Built-in 87 types of normal refrigerants PT comparison table for your convenience
  4. Zero Function: If a deviation occurs at zero point, use ZERO button to zero out and correct the system.
  5. Two overload warning indications: The screen displays ALARM or if the overload is too high, the ALARM & backlight will flash simultaneously.
1. Pressure range: Red gauge: -01-5.515MPa(0 800psi)
                              Blue gauge: -01-3.448MPa(0-500psi)
2. Resolution: 0.001MPa, 0.1psi
3. Accuracy: ±0.5%FS
4. Sampling period: 1s
5. Temperature unit: ℃/F
6. Backlight time: The backlight will be off after 3s, 4s, 5s, 10s or 15s as set in case of no operation.
