Description
HALO™ Bluetooth® pH microelectrode is a refillable glass pH sensor with a 3 mm tip designed for laboratory measurements in small sample volumes at universities, in pharmaceutical laboratories and in biotechnological research. Covering the range pH 0 to 13, the electrode combines an open ceramic junction, a spherical sensing tip and a silver-free Viscolene hard-gel electrolyte together with a double Ag/AgCl reference. Measurement data are transmitted wirelessly via Bluetooth® 4.0 over up to 10 m to the free Hanna Lab App or to a paired edge® blu pH meter. One-press connect pairing, a blue Halo status LED and on-board calibration storage simplify daily work, while a button press tags samples for easy retrieval later. Power is provided by a replaceable CR2032 lithium battery offering approximately 500 hours of operation. Overall length is 183 mm, with a 120 mm glass body of 3 mm outer diameter. The electrode from manufacturer Hanna Instruments is supplied with storage solution, cleaning solution, pH 7.01 and pH 4.01 buffers, battery, quality certificate and instruction manual as a single-piece pack.

Questions about HALO - micro pH electrode, no temperature, with Bluetooth® Smart Technology
What is this article?
HALO - micro pH electrode, no temperature, with Bluetooth® Smart Technology 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.
