The HS2 is a portable handheld display designed for use with the new Hydrosense II soil-water sensing system. When used with the CS658 or CS659 portable soil-water probes, it serves as the upgraded replacement for the earlier Hydrosense system. The device features a redesigned handheld unit and improved probe construction for enhanced usability. Its compact, ergonomic design and one-handed button operation make it highly convenient for field applications.
