If you would rather pay with a check, follow these following steps to get your unit calibrated using the Calibration Order Form. Please note, paying by check will delay the processing time by three or more additional business days.
1. Download and print the Calibration Order Form (see link in "Attachments" below). Fill it out to the best of your ability.
2. Package your unit in a small box or padded envelope and include your Calibration Order Form. Send them to:
KHN Solutions, Inc.
Attn: Calibration Lab
300 Broadway St, Ste 26
San Francisco, CA 94133
We recommend you send the package by USPS Priority Mail, but you may use another service if you prefer. Retain your tracking number just in case.
3. Once we have received your unit, we will calibrate and service your breathalyzer in our facility according to the service level you've chosen. Standard Servicing takes 10-14 business days and there is no additional cost. Expedited Servicing takes 4-5 business days and costs an additional $30.
