Description
Metal protective sleeve, polished brass, 315x12 mm, is a rigid housing for laboratory and process thermometers that need mechanical shielding during handling and measurement. The sleeve measures 315 mm in length and 12 mm in diameter and is intended for thermometer stems with a diameter of 7–9 mm. At the top it is fitted with a screw cap and ring so the instrument can be retained securely inside the tube while remaining accessible for reading. Fabricated from brass with a polished surface, the sleeve offers a robust metal barrier against knocks and everyday wear in temperature-measurement work. Supplied as one piece from manufacturer Amarell, it belongs to the range of accessories used for other temperature-measurement tasks where a durable brass guard improves instrument longevity. The polished finish supports straightforward cleaning and visual inspection of the assembly. Choose this length when a compact protective tube is required for standard laboratory thermometers within the stated stem-diameter range, without altering the thermometer’s measuring function.

What is this article?
Metal armour, brass polished, 315x12mm, above with screw and ring, suitable for is the article on this page. Luminix Health distributes Amarell for laboratory use. It sits in Temperature measurement accessories, inside Temperature measurement, in Lab instruments.
These are the connectors, the wells and the spare probes that complete a thermometer or a logger. A thermocouple connector of the wrong type silently adds an error. The accessory has to be the same sensor family as the meter.
A thermometer reports a temperature. A liquid-in-glass thermometer is a calibrated column. A digital thermometer is a sensor and a display, and the sensor, not the display, is what is calibrated. An infrared thermometer reads a surface and depends on emissivity. A data logger stores the reading over time. Without a stated uncertainty and a calibration point, the number is only an indication. The scale is maintained by the BIPM and compared by EURAMET. Accreditation is BELAC.
