Calibration requirement

Do you provide periodic calibration for the sensor (with certificate) as we are in a pharmaceutical manufacturing environment and need to comply with certain FDA requirements to use it as GxP data.
Currently we had purchased:

  1. IoT Long Range Wireless Air Flow Velocity Sensor
  2. Industrial IoT Long Range Wireless 4-20mA Current Receiver(build custom version with FSR 1.024V)



We purchase the air flow sensor from a third party vendor. This would be the company who would require calibration of the sensor.

What type of calibration would be required for a 4-20mA ADC input? We are an ISO 9001 certified manufacturer which does include calibration of manufacturing equipment.
