qMix Activation
There are two ways to activate the qMix app for your QuadraTherm 640i/780i: 1.) Purchase a qMix license per 640i/780i serial number upfront at point of purchase. 2.) Purchase a qMix license in the field for existing 640i/780i customers. View qMix Activation Quick Start Guide. Watch qMix Tutorial Video.

Upfront Purchase of a qMix License
The recommended way to activate the qMix app for your QuadraTherm 640i/780i is to purchase a qMix license for $350.00 per serial at time of purchase by using the model code “qMix” found the 640i/780i price list (must activate each meter per serial number).

Existing Customers: Purchase qMix License for Meters Already in the Field (firmware 1.0.87 or higher)
To continue using the qMix app for existing customers with QuadraTherm 640i/780i meters, you will need purchase a qMix license for $350.00 per serial number in the field. For existing customers, your 640i/780i must have firmware version 1.0.87 or higher to use qMix. For those customers who have already purchased the qMix license, your meter will still need to be activated per procedure below, but no additional cost will be incurred.

With upfront purchase, the qMix app for your specified meter serial number will be completely activated and set up in the factory. You will have use of qMix on that particular meter for unlimited gas mix creations and uploads. Once you receive your meter with the activated qMix license, you are ready to create custom gases-just a few simple set up steps.
