Description
Thermometer similar to ASTM 12F is a solid-stem laboratory thermometer covering −5 °F to +215 °F with a scale division of 0,5 °F. The white-backed scale improves readability, while a red special filling provides clear contrast along the capillary. Nominal dimensions are approximately 415–425 mm in length and 6–8 mm in diameter, corresponding to a typical length of 425 mm and diameter of 8 mm. The instrument is built for total immersion, finished with a rounded top and durable colouring suited to everyday laboratory use. Supplied as 1 pc from manufacturer Amarell, this model is described as calibratable, supporting subsequent verification where required. Red liquid filling against the white backing aids quick visual assessment of the Fahrenheit scale across the full measuring span. Solid-stem designs of this kind are common general-purpose and ASTM-style tools for laboratory temperature indication in °F. Country of origin is Germany (Bavaria). The glass stem construction and resistant scale marking follow established practice for enclosed liquid-in-glass thermometers intended for total immersion during measurement.
This article is part of Laboratory glass thermometers, in Temperature measurement.

Questions about Thermometer similar to ASTM 12F, solid stem, -5+215:0,5°F, white backed, red
What is this article?
Thermometer similar to ASTM 12F, solid stem, -5+215:0,5°F, white backed, red is the article on this page. Luminix Health distributes Amarell for laboratory use. It sits in Laboratory glass thermometers, inside Temperature measurement, in Lab instruments.
A liquid-in-glass thermometer is a calibrated column, often with a stated immersion depth, total or partial. The range and the division decide the reading. A partial-immersion thermometer read at the wrong depth is wrong by design.
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.
