This device allows you to monitor up to 3 mainlines. It incorporates 3 high precision vacuum sensors (with absolute measurements) and an internal temperature sensor. Thanks to its advanced energy management system, the device provides the best autonomy while being environment-friendly.  Indeed, you can count on a very high-quality Li-Ion battery that is kept re-charged by the integrated solar system.  In periods of insufficient sunlight, the device uses the primary Lithium battery.  The system automatically switches back to the rechargeable power source as soon as solar energy becomes available. The average battery life for the Li-Ion rechargeable battery is 4 years. The primary battery typically lasts much longer.

This device delivers the same functionality of 3 devices with a single vacuum sensor at a fraction of the cost.  It is highly recommended when mainlines are less than 250ft (76 m) apart.

Installation is very easy, no sophisticated equipment required.  The module has been built to stay outdoor all year long.  No need to deinstall and re-install between sugaring seasons. 

For isolated mainlines, it might make more sense to consider REDBV1.

• module REDBV3 in a high-quality outdoor industrial enclosure
• antenna
• 1 18650 Li-Ion rechargeable battery and 1 Lithium 19000mA at 3.7V
• adapters to connect the vacuum sensors to 5/16″ tube going to each of the 3 mainlines
