Hanna HI1285-8 GROLINE COMBO PROBE FOR HI981420 NUTRIENT MONITOR

The HI1285-8 industrial combo probe conveniently measures pH, EC/PPM, and temperature with a single rugged probe.  The conductivity sensor of the probe is placed below the pH electrode to provide greater protection in reservoirs.  Combo probes use just 1 electrode cord for fewer wires to manage in the reservoir.

  • One probe. One cord. Three measurements.
  • Built-in temperature sensor ensures fast, temperature compensated readings even during sudden temperature fluctuations.
  • Built for growers.

Details

Pre-Amplified pH Electrode

The pH electrode circuit has a built-in amplifier that serves to reduce the effects of electrical noise on the high impedance pH measurement. Electrical noise can come from motors and pumps that are common in greenhouses and grow rooms. The single reference junction design of the pH electrode has a cloth junction that allows ion movement between the inner gel electrolyte and the sample being measured. The advantage of the cloth junction is that it can be extracted from the probe, exposing a fresh surface when readings become drifty or erratic. These features make this probe ideal for use in fertilizer solutions.

Built-In Temperature Sensor

pH and EC/TDS readings must be temperature compensated in order to obtain accurate results. The built-in temperature sensor of the HI1285-8 provides a speedy temperature reading which is then used to adjust the pH and EC/TDS results accordingly.

Polypropylene Body

The polypropylene body of the HI1285-8 houses all three sensors within a sturdy, single body design. The polypropylene plastic is a high quality plastic that is chemically resistant to many aggressive chemicals.
