HI1285-6

pH/EC/TDS Multiparameter Probe with CAL Check

Description

Measure pH, conductivity (EC), and TDS (ppm) with the HI1285-6 multiparameter probe.

Perfect for measurements in greenhouses, water treatment, and boilers and cooling towers with a polypropylene body, built in temperature sensor, and pre-amplified pH electrode. The HI1285-6 is designed for use with HI9813-6 Portable pH/EC/TDS/Temperature Meter with CAL Check™.

•  3 in 1 probe with pH, conductivity (EC), TDS (ppm), & temperature sensors.
•  Great for hydroponics, aquariums, pools, & ponds.
•  Pre-amplified for more accurate readings.

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 HI1285-6 provides a speedy temperature reading which is then used to adjust the pH and EC/TDS results accordingly.

  DIN Connector with CAL Check
•  The HI1285-6 uses a DIN connector.
•  This type of connector is generally proprietary to the meters they are supplied with and may not be interchangeable.
•  The connection of the HI1285-6 enables the CAL Check function on the HI9813-6 portable multiparameter meter.

  Polypropylene Body
•  The polypropylene body of the HI1285-6 multiparameter pH probe 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.

  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.
