The Test Report and the Calibration Certificate are two different types of quality control records that are available from RKI with purchase of a GX-3R, GX-3R Pro, GX-Force, 04 Series, or GasWatch 3.

Test Reports - shipped with each instrument at NO CHARGE

Most of RKI's portable instruments are manufactured in Japan. When an instrument from the above list ships from Japan, a Test Report is included in the box, which shows the instrument has passed calibration and all the Quality Control inspections for that instrument. 

Calibration Certificate - available upon request for a $10 fee 

If you require a calibration certificate, it is best to order this with your instrument. RKI will calibrate the instrument prior to shipment and provide an RKI Calibration Certificate.

A Calibration Certificate is a certificate generated after calibrating the instrument with a NIST (National Institute of Standards and Technology) traceable source. This certificate will include calibration values as well as serial / lot numbers for the traceable test gases or equipment used to calibrate the instrument.

RKI offers two types of Calibration Certificates:

1.  Riken's Traceability Certificate 

Issued if a Calibration Certificate is requested after the order is shipped (even if it's a 4-gas unit)

2.  RKI's Calibration Certificate.

Issued if a calibration certificate is requested before the order is shipped (even if it's a 4-gas unit) *Includes the cylinder's expiration date which the Test Report and Traceability Certificate do not include.
