Supply Chain Solution
The water resistant GL300A is designed for logistics companies to track shipments on third-party trucks. These third-party trucks do not allow full telematics product installations and require a battery powered product for easy installation and removal. The product contains built-in sensors for recording temperature, humidity and light levels, making the product ideal for monitoring perishable goods such as fruit, vaccines and pharmaceuticals in cold chain logistics. Its large and rechargeable battery allows the product to operate for ninety-five days while providing location updates in ten-minute intervals.
Simply pass the product to the driver of the truck for fool-proof installation and no matter what orientation the product is placed, its front and rear internal GPS antennas allow reliable GPS positioning. Its built-in light sensor can also trigger alerts for tamper attempts. Drivers can place the product inside the refrigerated compartment and use the optional external GPS antenna to ensure accurate positioning.
