Benefits: Easy access to all your calibration records, track status, manage, share & much more

Hardness Tester Scales:

HRA, HRB, HRC, Etc.,

On-Site Calibration Cost: $175.00/each

Calibration – Guaranteed Lowest Price (C-GLP): CAL LAB ACCESS, LLC guarantees the lowest price for calibration services in USA. This applies ONLY to the items that are sent in for LAB calibration services and are in working condition (does not require repair), other terms and conditions apply.

RUSH Calibration:

Available at additional cost (please contact us to schedule an on-site calibration)

Calibration Methods:

We use ASTM E18 standard as a reference procedure to collect and report the data, OEM recommendation and laboratory developed calibration procedures to calibrate these units. ALL calibration data templates meet the requirements of SI Units.

Calibration Standards:

We always use traceable and/or accredited Laboratory Standards, reference test blocks.

Test Points:

Hardness Testers will be calibrated up to three (3) points on one (1) hardness scale (example: HRC)

If you require more than one hardness scale to be calibrated such as (HRB & HRC), additional fees apply.

Turnaround-time (TAT):

On-site service as per confirmed schedule date.

Calibration Certificate:

Every unit received for calibration will be shipped along with its calibration certificate and with a unique identification number (regardless of final result, whether unit pass or fail). Calibration Certificate will show the final result of the unit.


Our Laboratory Standards are always traceable to SI Units through National Metrology Institutes (NMIs), such as NIST USA, NRC Canada, etc.

Quality Compliance:

ALL our documentation is in compliant with ISO/IEC 17025:2017, ISO 9001, ISO 13485, AS 9100, ANSI/NCSLI Z-540-1 & GMP requirements.

Calibration Data (As Found):

We always provide as found calibration data for ALL units received in for calibration services.

Calibration Data (As Found & As Left):

If as found data shows unit is out of tolerance/specifications, our team will contact you to discuss several options on repairs (or) adjustments. Once approved we will attempt to repair and/or adjust the unit.

If and only if repairs/adjustments are successful, then as left data will be collected and submitted as part of the certification.

If repair/adjustments attempts are UNSCUCCESSFUL, then as left report will provide brief explanation about failure. An evaluation fee applies.


If you believe that your instrument is not working properly, our technical team can evaluate the unit and advise you for the next step. Usually for these units we recommend our customers to send to manufacturer for repair services. Our customer support team can assist you and able to handle OEM RMA process and send the unit for repair on your behalf, provided customer approves and paid in advance repair and evaluation cost including shipping and handling fee.
