Manual Thermometers
Mercury, non-mercury (liquid in glass), or bimetallic thermometers with analog displays, for general and application-specific use, with various temperature-range capacities and accuracies; may be traceable or certified to international standards.
In 1714, the mercury-in-glass thermometer was invented in Europe by physicist Daniel Gabriel Fahrenheit. Typically, the mercury is contained in a reservoir that opens to narrow glass tube. The distance that the mercury flows into the tube is dependent on the temperature to which the thermometer is subjected. The space above the mercury may be filled with air or an inert gas, or it may be a partial vacuum.
Thermometers are calibrated by exposing them to a known temperature and then marking the height of the mercury at that temperature. For example, one might calibrate to the freezing temperature of water (0°C or 32°F) by placing the thermometer in a mixture of ice and water. Then the thermometer could be submerged in boiling water to determine the point where the water changes from a liquid to a vapor (100°C or 212°F).
Mercury thermometers are still considered to be some of the most accurate temperature indicators. They can be used for a wide range of temperatures, from -37°C to 356°C (-35°F to 673°F). Modifications such as adding an inert gas above the mercury or replacing the glass with fused quartz can extend the upper temperature limit to as high as 800°C (1,470°F).
Mercury cannot be used below -38.83°C (-37.89°F), the temperature at which it becomes a solid. Moreover, nitrogen in the thermometer can flow down into the column and become trapped if the mercury solidifies, which makes the thermometer unusable. Use a thermometer that contains a mercury-thallium alloy for measuring lower meteorological temperatures – it will remain liquid to -61.1°C (-78.0°F).

GA International Acid & Base-Resistant Thermal-Transfer Labels 1.5" x 1" / 38.1mm x 25.4mm Rectangle White From -80°C to +121°C (-112°F to +250°F). Min application temp: -20°C (-4°F)
AcidiTAG™ is our line of labels designed to resist exposure to a wide pH range of substances, including concentrated acids and bases, commonly used as laboratory reagents. The permanent, acid and base-proof labels are ideal for identifying containers used to store highly corrosive reagents used in organic chemistry and forensics labs, for analytical research, by environmental/agriculture laboratories, and public utilities that routinely test water quality. The acid-resistant labels will withstand long-term exposure as well as immersion in concentrated Sulfuric acid (H2SO4), Nitric acid (HNO3), Hydrochloric acid (HCL), Hydrofluoric acid (HF), Trichloroacetic Acid (TCA), as well as Sodium Hydroxide (NaOH). Perfect for use in clinical and research facilities employing corrosive acids and alkalis. Compatible with all common thermal-transfer barcode label printers, the labels can be printed using our XAR-class of ribbons, with barcodes and other printed information.
