Product code: IC-HI1285-7

Order Me In, Once ordered this item will likely dispatch before the 09th of November 2025, call 1300 737 871 (NZ 0800 737 871) to confirm.

The HI1285-7 is a 3-in-1 pre-amplified multiparameter probe that measures pH, EC/TDS, and temperature within a single polypropylene body. 
 
  • The pH portion of this probe is constructed with a cloth junction, maintenance-free polymer gel electrolyte, and a low-temperature glass sensing bulb. 
  • The EC/TDS portion of this probe utilizes two stainless steel pins for an amperometric determination of conductivity and total dissolved solids. 
  • A built-in temperature sensor ensures that both pH and EC/TDS readings are compensated for temperature variations in both standards and samples.

The HI1285-7 is a 3-in-1 pre-amplified multiparameter probe that measures pH, EC/TDS, and temperature within a single polypropylene body. The pH portion of this probe is constructed with a cloth junction, maintenance-free polymer gel electrolyte, and a low-temperature glass sensing bulb. The EC/TDS portion of this probe utilizes two stainless steel pins for an amperometric determination of conductivity and total dissolved solids. A built-in temperature sensor ensures that both pH and EC/TDS readings are compensated for temperature variations in both standards and samples.
The design consideration for the HI1285-7 is ideal for measuring the pH, EC/TDS, and temperature in greenhouses, hydroponics, and other agricultural applications. The HI1285-7 is designed for use with Hannas HI9814 portable multiparameter meter.
Features:
- 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.
- 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.
- pH and EC/TDS readings must be temperature compensated in order to obtain accurate results. The built-in temperature sensor of the HI1285-7 provides a speedy temperature reading which is then used to adjust the pH and EC/TDS results accordingly.
- The polypropylene body of the HI1285-7 houses all three sensors within a sturdy, single body design. This body material is suitable for a wide range of applications and excels in measurements with portable meters due to its durability. The fins around the spherical glass pH bulb minimizes breakage due to accidental bumping or dropping of the electrode. The polypropylene plastic is a high-quality plastic that is chemically resistant to many aggressive chemicals.
- The HI1285-7 uses a quick connect DIN connector. This type of connector is generally proprietary to the meters they are supplied with and may not be interchangeable. The HI1285-7 is designed for use with Hannas HI9814.
