Varifan Controllers


The OPTI-GAIN series provides producers with up to date flock performance information and gathers data for managing future flocks.  Being well informed, you can take corrective action in order to optimize flock weight gain and overall performance.  Depending on the type of platform used, the OPTI-GAIN series can weigh and collect data for broilers or turkeys.

The display is designed with 6 hot buttons for quick and easy access to parameter settings, and has an easy to view 8 line by 21 character LCD screen.

Remote access, monitoring, data logging and management

The OPTI-GAIN series amounts to much more than user-friendly controllers when teamed up with the FarmQuest online management service.  Together, they make for a powerful management tool that you can access from anywhere in the world.  Your controllers are connected to the FarmQuest server, which constantly uploads data and enables you to easily view, analyze and compare results with those of current or previous production batches.  Also, when an out of limits condition exists, FarmQuest automatically sends you a warning by email or SMS text messaging.

The OPTI-GAIN series of controllers is also compatible with our WiFarm wireless network, specifically created for farm applications.  Its easy installation eliminates trenching and underground wires that can increase the risk of lightning strikes. 

The WiFarm wireless network and FarmQuest online management service have been designed exclusively for the livestock industry by M2M TeleSystems.  To learn more about these, click on their respective logos below.
