Velstretch WrappingVelstretch Wrapping

Stretch Velcro wrapping to secure the body of the plantReduce maintenance and installation issues to accommodate growthVelstretch made of breathable, porous nylon and Lycra spandexCollects moisture and conducts water from the stem and sensor

Waterproof Membrane ClothWaterproof Membrane ClothWaterproof membrane cloth wrapped over the sensorMembrane cloth made of Teflon fabricBlocks rainwater and extracts water vaporReducing condensation build-up inside the sensor

Reflective ShieldReflective ShieldMaterial consists in 2 reflective layers of flexible film on 2 polyethylene bubbles

Required to block radiant heat

Provides a conductive barrier

Internal Thermocouple Wiring Internal Thermocouple Wiring

Thermocouple wiring similar to Dynagage sap flow sensorsNo change or reduction on accuracyAll EXO-skin come with sealed water tight locking connectorsLifetime expectations 3-5 years
