Description
Documents

The HI981405N is ideal for growers that need to monitor pH and conductivity (EC) for optimal plant growth. This meter continuously monitors and displays the values of a solution on an easy-to-read set of LCDs.
Two parameters with a single instrument.
Supplied complete and ready to use.
Great for agricultural, horticultural, and hydroponics applications
HI 981405N (pH and EC) is specially designed to meet the needs of simple continuous monitoring. You can simply install the meter above the sample to be tested for continuous measurement.
The HI 1286 gel-filled pH electrode features a waterproof sheath to protect BNC connector against humidity and vapours. Moreover, the unique design of the electrode provides longer life in aggressive solutions. The meter is equipped with two large LCDs for easy-to-read measurements even from a distance. Measurements are accurate and the meters can be calibrated at one or two points for pH, and at a single point for EC. You no longer need to worry about battery changes because these units run without interruption on 12 Vdc power supply.
