Hanna GroChek pH & TDS Combo Continuous Reading Meter
This continuous reading meter works great for agricultural, horticultural, and hydroponics applications where pH and TDS levels need to be continuously monitored for optimal plant growth. This instrument continuously monitors and displays the values of a solution on an easy to read set of LCDs. The gel-filled pH electrode is replaceable and the BNC connector is protected behind a waterproof sleeve. The unique design of the electrode guarantees greater clogging resistance in fertilizer solutions with high concentrations of phosphate, nitrate, etc. TDS measurements are performed using the 4-4-2 conversion factor of 0.7 so you do not need to convert the readings. FEATURES Displays pH & EC simultaneously Adjustable setpoints Space efficient Two parameters with a single instrument Advanced electrode technology Simple operation and maintenance Ready to use Includes pH electrode, TDS probe, grounding bar, calibration solutions, screwdriver for calibration, 12V DC adapter, and instructions
