After the two year calibration, can I just purchase a new reader and not the whole kit? Or can I send it in to be re-calibrated without having to purchase another kit?

The LogTag vaccine monitoring kits can be sent back in to be re-calibrated. This service can be purchased directly from our website here - https://microdaq.com/vaccination-recalibration.php Once you choose the type of calibration you wish to purchase, fridge, freezer, or fridge and freezer the price will show up. After you place the order we will email you with return instructions to ship your logger(s) back to us. If you have any questions please call our office or contact us.
