HI1285-8

Description

The HI1285-8 multiparameter probe measures pH, EC/TDS, and temperature in one convenient, rugged probe. Use with the HI981420 GroLine Monitor to provide around-the-clock, continuous monitoring of pH, conductivity (EC & TDS), and temperature in hydroponic nutrient solutions. Grow better with GroLine.

  •  Built-in temperature sensor ensures fast, accurately compensated readings even during sudden temperature fluctuations.
•  One probe. Three measurements.
•  Specialized for hydroponics with a renewable junction for extended life.

  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.
•  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.

  Amperometric EC/TDS Sensor
•  EC/TDS readings are performed by a two-pin amperometric sensor.
•  An alternating voltage is applied to the sensor and the amount of current that passes 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 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.
•  This body material is suitable for a wide range of applications and excels in harsh grow environments due to its durability.
•  The polypropylene plastic is a high quality plastic that is chemically resistant to many aggressive chemicals and minimizes breakage due to accidental
bumping or dropping of the electrode.

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