Mercury is the traditional fluid used for thermometers and other indicating instruments. Its properties are well-known and understood. Some published test methods specify use of mercury-filled thermometers, but many of these standards are being revised to avoid problems related to its use. Customers should be aware of state or local ordinances controlling shipment or sale of mercury instruments in their area. Please check for restrictions before ordering.
