Description
Precision thermometer, enclosed type, is a laboratory glass thermometer for accurate temperature measurement from −5 to +100 °C. It has an overall length designation L 420 and a red filling that gives a clear liquid column against the scale for straightforward reading during routine checks. The enclosed construction protects the capillary and scale under normal laboratory handling, supporting use in baths, incubators, reaction vessels, and general temperature monitoring. Supplied as 1 pc(s) and weighing 0,090 kg, the instrument is convenient for benchtop work and organised storage with other measuring tools. Each unit from manufacturer ROTH SELECTION includes a factory test certificate, providing documented verification at manufacture for quality records and controlled procedures. Categorised among glass thermometers for temperature and monitoring, it suits analytical, process, and teaching laboratories that prefer certified liquid-in-glass thermometry. The defined range, red filling, and enclosed design make it a practical choice where reliable visual temperature indication is required without electronic instrumentation.
This article is part of Laboratory glass thermometers, in Temperature measurement.

Questions about Precision thermometer, enclosed type, L 420, -5 - +100 °C, 1 unit(s)
What is this article?
Precision thermometer, enclosed type, L 420, -5 - +100 °C, 1 unit(s) is the article on this page. Luminix Health distributes Carl Roth 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.
