Dilution Solutions NDS Nutrient Monitor Kit, 1 1/2 in | HYKMON150 Hi-Flo, 40 GPM

Dilution Solutions Nutrient Monitor Kit for the Hi-Flo NDS

A water-powered panel can dose every product perfectly and still leave you guessing about what actually reaches the plants. This kit, part HYKMON150, puts a reading on the finished solution at the outlet end of a 1 1/2 inch Hi-Flo system. The Hi-Flo water-powered series runs from 5 to 40 GPM. Solution coming off the last doser first passes through the kit's own mixing chamber, so the probes see an even blend. A tee after the chamber carries a pressure gauge, stepped down through reducer bushings. Next comes the probe holder assembly, where the monitor's in-line probes sit in the flow. The monitor displays EC or ppm, pH and temperature on an easy-to-read screen. The probes and calibration steps come from Bluelab. Beyond the probes, a cross fitting carries a test port with its own ball valve and hose adapter. Unions at both ends let the whole section come off the panel for service. The box also holds the elbows, nipples, tees and two rolls of thread seal tape. Dosatron dosers, the starter kit, extra mixing chambers and the water hammer arrestor kit are sold separately.

Setting Up the EC and pH Monitor at the End of the Panel

Plan for a power outlet close to the panel, mounted above the dosers where water cannot reach it. Calibrate the pH probe before it goes into the line, following Bluelab's calibration instructions. Keep the protective casing on the probe until that moment, because it holds the tip wet and keeps the calibration stable. Wrap every male thread with five or six turns of tape, clockwise, and use no pipe dope. Watch the flow arrow on the mixing chamber as you fit its nipples. Seat both probes in the probe holder assembly once the plumbing is complete. Bring the water up slowly the first time. Expect odd EC numbers while the system primes, and give the display a little time to settle. Then draw a sample from the test port and check it with a handheld meter. That same port handles volumetric tests and flushing the line without wetting the floor. Clean and recalibrate the probes on a regular schedule, and replace them when they stop holding a calibration. If the system will sit idle, store the probes in KCl solution rather than leaving them dry.

Key Features

• In-Line EC, pH and Temperature: Reads the finished solution as it leaves the panel.
• Built-In Mixing Chamber: Evens out the blend before it reaches the probes.
• Pressure Gauge: Shows line pressure at the outlet end of the panel.
• Sample Test Port: A ball valve and hose adapter for meter checks, volumetric tests and flushing.
• Bluelab Probes: pH and conductivity probes calibrated to Bluelab instructions.
• Union Connections: The whole section comes off the panel for service.
