GroChek® Combo - 2 meters in 1: Monitors pH and TDS
- Easy to install
- Professional electrodes and 12VDC power supply included
HI 981404N and HI 981405N are ideal for agricultural, horticultural and hydroponics applications where pH and TDS or pH and EC levels need to be continuously monitored for optimal plant growth. HI 981404N and HI 981405N continuously monitor and display the pH and TDS or pH and EC values of a solution on an easy to read set of dual LCD's. The HI 1286 gel filled pH electrode is replaceable and the BNC connector is protected behind a water proof sheath. 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. Both models are equipped with a grounding bar to ensure more accurate pH measurements and longer electrode life. The HI 981404N and HI 981405N are compact and easy to install and use. This makes them ideal for all continuous monitoring applications.
HI 981404N is supplied complete with HI 1286 pH electrode, HI 7634 TDS probe, HI 1283 grounding bar, pH and TDS calibration solutions (20 mL each), screwdriver, 12 VDC adapter and instructions. |
