The glass thermometer must be the most familiar of all thermometers. Apart from its industrial and laboratory use, it finds application in both domestic and medical fields.

when to use them, as well as the various methods of calibration. Liquid-in-Glass Thermometers Let’s start our story with one of the most common thermometers used today, the liquid-in-glass (LiG) thermometer. A LiG thermometer, by definition, is a glass capillary tube with a liquid-filled bulb at one end.

As the temperature of the. checks on reference thermometers and single-point checks on working thermometers are also described. 2 Thermometer Calibration Schedule Good laboratory practice with regard to the calibration of liquid-in-glass thermometers is as follows: Type Calibration Schedule Reference Initial complete calibration, traceableFile Size: KB.

Volume 2 of the Handbook of Temperature Measurement, prepared by the CSIRO National Measurement Laboratory, Australia, discusses the operation, calibration and usage of resistance and liquid-in-glass standard-platinum-resistance thermometers and industrial-resistance thermometers are examined, and details on a variety of resistance-measuring.

This test method covers visual and dimensional inspection and test for scale accuracy to be used in the verification of liquid-in-glass thermometers as specified in Specifications E1 and E However, these procedures may be applied to other liquid-in-glass thermometers.

CALIBRATION THERMOMETERS Calibration thermometers (table ) can be either a liquid-in-glass (mercury or spirit) or thermistor (digital) type thermometer, but must carry a current NIST certification or NIST-traceable certification that is no more than 2.

metal coil, which necessitate calibration of the ther-mometer before reuse. Bi-metal coil thermometer calibration method Calibration for use in hot processes and products (boiling water method): Once these supplies are assembled, the following steps are used to calibrate bi-metal coil thermometers for use in hot processes.

Size: KB. Calibration of a Liquid in Glass Thermometer Example. Before commencing with the thermometer’s calibration, we must visually inspect the thermometer to ensure that there are no malfunctions such as gaps in the measuring liquid, errors in the measuring scale, etc.

Each item is tested and calibrated in our exclusive triple accredited/registered ISO/IECA2LA accredited laboratory against equipment whose calibration is traceable to NIST. Ideal for use in chemical laboratories, universities, scientific institutions, food and beverage processing,petrochemical laboratories, pharmaceutical industry.

Scope. This test method covers visual and dimensional inspection, test for permanency of pigment, test for bulb stability, and test for scale accuracy to be used in the verification of liquid-in-glass thermometers as specified in Specification E1.

It would melt. The temperature of lava (molten rock) is as hot as liquid metal, and lab thermometers are typically metal and glass. Thermometers made from ceramic might survive, but. Historically, thermometers were mechanical (mostly bi-metal), which evolved into liquid in glass thermometers.

However, as technology improved, consistent dimensions in glass manufacturing processes were achieved. These types of thermometers were able to indicate changes in temperatures, based on the effect of how the material to expanded or.EQUIPMENT--Discontinuance of field use of mercury liquid-in-glass thermometers In Reply Refer To: Novem Mail Stop OFFICE OF WATER QUALITY TECHNICAL MEMORANDUM NO.
