Gro-Check Combo Continuous Meter

The Gro-Check Combo is ideal for agricultural, horticultural and hydroponics applications where pH and TDS levels need to be continuously monitored for optimal plant growth. HI 981404 continuously monitors and displays the pH and the TDS values of a solution on an easy to read set of dual LCD's. In order to help meet the specific nutritive requirements of different types of crops, the alarm setpoints are operator selectable in both the pH and TDS ranges. When the pH and/or TDS value of the solution is outside the preset range, the corresponding red LED alarm comes on. This feature makes it easy to optimize the effectiveness of the nutrient solutions used for plants and flowers. The meter is supplied with an advanced non-clogging Teflon® junction pH electrode and a rugged TDS probe. Each are specifically designed for growing applications and last for long periods of time even when used in extremely aggressive fertilizer solutions. The Gro-Check Combo can be calibrated at one or two points in the pH range (pH 4 and 7) and at one point in the TDS range. The instrument is powered by a 12VDC transformer, and comes equipped with a grounding bar which ensures longer electrode life and more accurate pH measurements. Compact and easy to install and use, is the ideal solution to your continuous monitoring needs.
