I have Retrotec fans and gauges. How often do I need to calibrate the equipment?
Our manufacturer's recommendation for calibration is as follows:
- Retrotec fans: Every 5 years.
- DM-2 Mamometer: Every 2 years or if the Mamometer fails a field check.
- DM32 / DM32 WiFi Mamometer: Every 5 years or if the Mamometer fails a field check.
Please review the DM32 and DM-2 Manuals on how to perform a field check.
This only covers our manufacturer recommendation. The energy standards (EN13829, ASTM, ATTMA, USACE, etc...) that you are using for test results may have different calibration intervals. Please consult the energy standards for the specifc equipment calibration intervals.
