Description
Thermometer similar to ASTM 21F is a precision rod-form laboratory thermometer for the range 174 °F to +188 °F with a scale division of 0,2 °F. The white-backed scale enhances contrast, and a special capillary inner coating is combined with a non-wetting blue special filling that stays clearly visible during use. Overall size is approximately 270–280 mm long by 6–7 mm in diameter, with typical values of 280 mm length and 7 mm diameter. The design is for total immersion, with a rounded closed top and resistant colouring of the scale markings for durability in daily laboratory handling. It includes a factory test certificate with one test point, supporting documented performance checks in quality assurance and standardised testing. This solid-stem inclusion thermometer from manufacturer Amarell suits general laboratory applications, ASTM-related procedures, and work requiring fine Fahrenheit resolution across a limited interval. Blue filling on the white backing assists reliable observation of the indicated temperature over the full specified measuring span.

Questions about Thermometer similar to ASTM 21F, solid stem, 174+188:0,2°F, white backed,
What is this article?
Thermometer similar to ASTM 21F, solid stem, 174+188:0,2°F, white backed, is the article on this page. Luminix Health distributes Amarell for laboratory use. It sits in Thermomètres en verre de laboratoire, inside Mesure de température, in Instruments de laboratoire.
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.
