Description
Portable meter for pH/°C for direct soil measurement incl. probe HI12923 is a waterproof handheld instrument designed for soil samples and in-situ soil pH determination with simultaneous temperature reading. Moistening the soil before measurement facilitates contact; the kit includes an auger for preparing a small measuring hole and the HI12923 glass-body electrode with conical tip and integrated temperature sensor, also suitable for diluted soil solutions. For higher accuracy or stony soils, the supplied HI7051 soil preparation solution is recommended. The meter forms part of the modern HI99xxxx series from manufacturer Hanna Instruments and uses Quick-DIN electrodes that keep the assembly fully water- and dust-tight. Two-key operation simplifies range and calibration selection, a multilevel LCD displays essential values, and the IP67 housing protects the electronics. On-screen electrode status supports timely maintenance. Scope of supply: HI12923 Quick-DIN electrode (1 m cable), auger, soil preparation solution, starter calibration solutions, cleaning solution, batteries, manual and quality certificate in a robust carrying case. pH range -2,00 to 16,00; temperature -5,0 to 105,0 °C.

Questions about Direct Soil Measurement pH Portable Meter
What is this article?
Direct Soil Measurement pH Portable Meter is the article on this page. Luminix Health distributes Hanna Instruments for laboratory use. It sits in pH electrodes & sensors, inside pH & electrochemistry, in Lab instruments.
A pH electrode is a glass membrane and a reference. It is a consumable: the glass ages, the junction clogs, and the reading drifts. A refillable electrode and a gel electrode differ in how they are maintained. The connector has to match the meter. The electrode, not the meter, is usually what is wrong.
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.
