FAQ

Most manufacturers recommend calibrating digital manometers annually (once every 12 months) to maintain accuracy. However, more frequent calibration may be necessary based on the frequency and criticality of use, or user/regulatory requirements.


- If the readings become inconsistent or appear inaccurate when compared against a reference standard.
- If the instrument shows signs of physical impact or exposure to harsh conditions.
- If the device is used in critical measurements or per company SOPs that prescribe calibration intervals.
- If “Calibration Due” reminders or stickers indicate the scheduled calibration date has passed.
- After repair or major maintenance on the instrument.
