PR52-33A - Industrial Temp. and Humidity Sensor Calibration Records

I am looking at purchasing a high quantity of these devices (40+). We are in a nutraceutical manufacturing environment and need to comply with certain FDA requirements.

Is each sensor that comes with calibrated? What calibration records can be obtained and where can I locate them?

We use Honeywell temp humidity sensor.

The calibration done by the sensor manufacture.
