PTC Metrology™ offers standard humidity certifications; which include as received and as returned data; a statement of uncertainty; laboratory conditions; and information on the primary standards. Please note that certification prices do not include any labor, adjustments, repairs or parts of the unit under test.
Certifications will satisfy most quality requirements by providing NIST traceable as received and as returned calibration results of the UUT (unit under test). The calibration point will be the ambient relative humidity reading in our calibration lab. In addition to the readings, certifications will include a statement of uncertainty, laboratory conditions, and information on the primary standards.

1 Point Temperature at Ambient (CERTDA) $125.00
3 Point Temperature -20° to 120°C (CERTTEMPA2LA) $250.00
NIST Traceable Certifications:
3 Point Temperature (CERTTEMP) $150.00
This cert will satisfy most Quality requirements by providing NIST traceable as received and as returned calibration results of the UUT (Unit Under Test). The calibration points will be of PTC®’s choice and will include three points across the UUT’s scale.
NIST Traceable Basic Cert-No Points (CERT) $105.00
This certification is best for customers only needing calibration traceability to NIST without adding the cost of logging the calibration results. Although no specific points will be logged, UUT’s referred to will be calibrated at three or more points over the UUT’s range.
This certification will not list any adjustments made to the UUT or out of tolerance conditions.
