GHL KH Director (Slave Unit) and Two 1000ml KHD Reagents. I bought this back in July from Premium Aquatics and set it up on November 14, 2020 once I got the doser. Works flawlessly, just set up a Geo CaRx and don't really need this at this time. PM is key. Comes with the following:
- KH Director device with integrated measuring cell
- Specially designed pH electrode for KH measurement
- Calibration fluid
- Silicone tube 5 m
- Flex-pvc tube 70 cm for reagent
- Power supply splitter cable
- Two unopened 1000ML Reagents
- Chart showing date of setup
- Receipt from Premium Aquatics
