Full Description Specification

The HI-12883 is a 3-in-one 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 utilises two graphite sensors 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 HI-12883 is ideal for measuring the pH, EC, and temperature in greenhouses, hydroponics, environmental monitoring, water treatment, wastewater treatment and boilers and cooling towers. The HI-12883 is designed for use with Hanna’s HI-991300 and HI-991301 portable multiparameter meters (new style).

Hanna Instruments offers a wide variety of electrodes that are designed for many different applications. The sensing material, body material, and connection type used are just some of the design considerations.

The HI-12883 multi-parameter probe includes pH, EC/TDS and temperature measurement in one convenient, rugged probe.

The HI-12883 is integrated with a solid-state pre-amplifier built into the handle to ensure against interference from transient electrical noise and fitted with a DIN connector and 1m cable.

Key features:

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 readings must be temperature compensated in order to obtain accurate results. The built-in temperature sensor of the HI-12883 provides a speedy temperature reading which is then used to adjust the pH and EC results accordingly.

Polypropylene Body

The polypropylene body of the HI-12883 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 minimises 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.

DIN Connector

The HI-12883 uses a DIN connector. The HI-12883 is made for use with Hanna’s new style HI-991300 and HI-991301 portable multiparameter meters. If you have an old-style meter model, please select the HI-1288.
