อุปกรณ์วัด Conductivity/TDS (pH & TDS Continuous Indicator)

HI 981404N-01

pH & TDS Continuous Indicator 

  • Two parameters with a single instrument
  • Advanced electrode technology
  • Simple operation and maintenance
  • Supplied complete and ready to use

HI 981404N-01 is ideal 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 LCD’s.

The HI 1286 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.

This model is equipped with a grounding bar to ensure highly accurate pH readings and longer electrode life.

The HI 981404N-01 is compact and easy to install and use making it ideal for all continuous monitoring applications.

Order Information:
HI 981404N-01 (115V) and HI 981404N-02 (230V) are supplied complete with HI 1286 pH electrode, HI 7634 TDS probe, HI 1283 grounding bar, calibration solutions, screwdriver for calibration, 12 VDC adapter and instructions.
