pH/EC/TDS Electrode for GroLine HI981420 HI1285-8

Producer: HANNA Instruments

SKU: HANNA-HI1285-8 Category: Hanna experimental measuring equipment

pH/EC/TDS Electrode For GroLine HI981420

The HI1285-8 multiparameter probe measures pH, EC/TDS, and temperature in one convenient, rugged probe. Use with the HI981420 GroLine Monitor to continuously measure and monitor pH, conductivity (EC & TDS), and temperature in hydroponic nutrient solutions.

GroLine Specialized.

One probe. Three measurements.

Built-in temperature sensor ensures fast reading, accurate compensation even during sudden temperature fluctuations.

Pre-amplified pH electrode

The pH electrode circuit has a built-in amplifier that serves to reduce the impact of electrical noise on high impedance pH measurements. Electrical noise can come from motors and pumps that are common in greenhouses. The single reference junction design of the pH electrode has a cloth junction that allows ion transfer between the internal gel electrolyte and the sample being measured. The advantage of the cloth junction is that it can be removed from the probe when the measurement becomes drifty or erratic. These features make this probe ideal for use in fertilizer solutions.

EC / TDS intensity sensor

EC/TDS readings are taken using a two-pole amperometric sensor. An AC voltage is applied to the sensor and the amount of current passed between the two stainless steel pins determines the amount of dissolved ionic solids present.

Built-in temperature sensor

pH and EC/TDS readings must be temperature compensated for accurate results. The HI1285-8's built-in temperature sensor provides a quick temperature reading which is then used to adjust the pH and EC/TDS results accordingly.

Plastic body

The polypropylene body of the HI1285-8 houses all three sensors in a rugged, durable body design. This body material is suitable for a wide range of applications and excels in harsh growing environments due to its durability. Polypropylene is a high-quality plastic that is chemically resistant to many harsh chemicals and minimizes breakage from impact or dropping the electrode.

DIN connector

The HI1285-8 uses a DIN connector. This probe is recommended for use with the HI981420 GroLine Hydroponic Nutrient Monitor for pH, EC, TDS and Temperature.
