Note: Calibration service providers other than American Innovations are not equipped to perform this type of calibration for MicroMax digital voltmeters.
The measurements of the device are verified against the specification, but no adjustments are made to the internal calibration constants. This is the type of calibration that happens when you send a MicroMax SRM100 Soil Resistivity and pH Meter to American Innovations.

Your calibrations become available when we approve the PO, and we send you an email. Wait for that email before you ship devices.
Paying by card? You pay on our payment provider’s secure page. Your calibrations are ready as soon as your payment is confirmed. We never see or store your card number.
You do not need to tell us before you ship.
We hold the extra devices when they arrive. We do not calibrate them until you tell us what to do. We email you, and the portal shows Action needed on your request.
For each extra device, choose one option:
To prevent delays, pack exactly the number of devices on your request.
Open the Track tab. Each request shows where it is:
Received → In Calibration → Ready to Ship → Shipped
The tracking number shows at the Shipped step. We also email you when we receive your devices, when the calibration is complete, and when your devices ship.
Sign in and open the Track tab. Download a certificate for each device. Every calibration keeps its own certificate, so a new calibration never replaces an earlier one.
Something wrong on a certificate? Find the certificate and select Request a correction. Tell us what is wrong. You do not send us anything, and there is no charge. Our lab checks the certificate against its records. Then we either issue a corrected certificate or tell you why the original is correct. You can request a correction for a limited time after we ship your device back.
Your calibrations are valid for 12 months from your order date. After that date, you cannot use them, and we do not refund or transfer them.
