Description
Precision thermometer with blue filling is a glass laboratory thermometer for temperature measurement in the range −38 to +2 °C. The instrument is designated L 401 and is intended for monitoring tasks where a clear, blue-filled capillary scale supports precise reading in cold or near-freezing conditions. It is supplied as 1 pc, with a listed weight of 0,060 kg, so the single unit is light to handle and store with other measuring instruments. Within labware for temperature and monitoring, this glass thermometer addresses applications that require a dedicated low-temperature span rather than a wide general-purpose scale. Blue filling improves visibility of the liquid column against the scale during routine checks. The thermometer from manufacturer ROTH SELECTION follows the stated L 401 designation and temperature limits given in the product data. Laboratories use such precision glass thermometers for bath control, sample conditioning, and environmental checks inside the indicated range. No sterility, calibration certificate, or extended performance data are claimed beyond the blue-filled precision thermometer identity, L 401 marking, measuring span −38 to +2 °C, unit quantity, and weight. The compact single-piece pack suits benches that need a focused low-range glass thermometer for temperature and monitoring work.
This article is part of Laboratory glass thermometers, in Temperature measurement.

Questions about Precision thermometer, blue filling, L 401, -38 - +2°C, 1 unit(s)
What is this article?
Precision thermometer, blue filling, L 401, -38 - +2°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.
