Description
Barometric Pressure Sensor USB is a compact laboratory accessory intended for use with NineFocus measuring devices. It plugs into the USB-A port and measures ambient atmospheric pressure to support dissolved oxygen determinations. The sensor has a net weight of 0,025 kg and a gross weight of 0,037 kg, making it easy to handle and store with other instrument accessories. Packaging measures 0,04 m in height, 0,07 m in width and 0,118 m in depth, giving a packaging volume of 0,001 m³. Supplied as one piece and originating from China, the unit integrates directly into the NineFocus workflow from manufacturer Mettler-Toledo OnLine. By providing continuous ambient-pressure data at the instrument, it helps maintain consistent conditions for dissolved-oxygen work without separate external barometers. The straightforward USB-A connection allows quick attachment or removal when measurement setups change. Its small footprint and low mass suit crowded benches where space and cable management matter. This accessory complements NineFocus systems that require reliable ambient-pressure input for oxygen-related analyses in routine laboratory practice.

Questions about Barometric Pressure Sensor USB
What is this article?
Barometric Pressure Sensor USB is the article on this page. Luminix Health distributes Mettler-Toledo OnLine 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.
