Description
Conductivity/TDS/°C probe with DIN quick connector and 1 m cable is a two-ring conductivity electrode designed for accurate multi-parameter sensing of conductivity, total dissolved solids and temperature. The probe is compatible with Hanna Instruments meters HI99300 and HI99301 in the 2018 version and is built to maintain high measurement accuracy across the full measuring range of those instruments. An integrated temperature sensor enables automatic temperature compensation of the conductivity and TDS readings, reducing the need for manual correction during routine laboratory or process checks. This sensor from manufacturer Hanna Instruments connects via a DIN quick connector, allowing rapid attachment and removal while keeping the cable length practical at 1 m for bench or portable use. Supplied as one piece, the probe has a net weight of 0,11 kg and a gross weight of 1,11 kg, making it easy to store and deploy alongside the matching handheld meters. Water-quality laboratories, industrial QC teams and field technicians working with HI99300 or HI99301 can rely on this two-ring design for stable conductivity and TDS acquisition with automatic thermal compensation built into the measurement chain.
This article is part of Conductivity meters & cells, in pH & electrochemistry. See also pH meters.

Questions about EC/TDS probe with quick connect DIN connector for HI99300/HI99301
What is this article?
EC/TDS probe with quick connect DIN connector for HI99300/HI99301 is the article on this page. Luminix Health distributes Hanna Instruments for laboratory use. It sits in Conductivity meters & cells, inside pH & electrochemistry, in Instruments de laboratoire.
A conductivity meter and its cell measure how well a solution carries current. The cell constant is the geometry that converts conductance to conductivity, and it is calibrated with a standard. Temperature compensation matters because conductivity rises with temperature.
A pH meter is a voltmeter on a glass electrode. The voltage tracks hydrogen-ion activity, and the electrode is converted to pH only after it is adjusted with buffers of known value. Conductivity measures how well a solution carries a current, which for dilute salts tracks concentration. Dissolved oxygen and titration are further electrodes on the same idea: a sensor, a standard, and a reading that is only as fresh as the calibration. Buffer values and chemical identity sit on PubChem. Accreditation of the calibration laboratory is the field of BELAC and EURAMET.
