Description
The KHD & GHL Doser 3 EXT Bundle combines the KH Director with the GHL Doser 3 EXT to provide a complete, ready-to-use solution for automated alkalinity (KH) measurement and controlled dosing within an existing GHL system.
The KH Director performs fully automated alkalinity measurements and can automatically adjust dosing based on measured values. The GHL Doser 3 EXT supplies the required dosing pumps and integrates via PAB, ensuring stable and reliable communication with the master device.
This bundle is ideal for users who already operate a compatible GHL master device and want a modern, precise, and well-integrated solution for KH monitoring without having to assemble individual components.
Compatibility and requirements
The GHL Doser 3 EXT is an extension unit and requires one of the following GHL master devices:
- ProfiLux 4
- GHL Doser 3 Standalone
- GHL Doser 3 Maxi Standalone
Bundle advantage
This bundle applies a predefined bundle discount to the included products, offering a clear price advantage compared to purchasing the KH Director and GHL Doser 3 EXT separately.
