Mercury Device Exchange
EHS will exchange your mercury thermometer (or other mercury containing device) with a mercury free one. To determine if your thermometer contains mercury, examine the fluid. If the fluid is silver colored, it is mercury. If it's red, it's alcohol, and if it's blue or green, it's the new environmentally safe fluid. Mercury is a toxic element and when a mercury thermometer is broken, special care must be taken to clean it up. Thermometers broken in water baths or ovens tables are particularly troublesome to clean up. Mercury manometers contain large amounts of mercury and many thousands of dollars can be spent cleaning up after a spilled or broken manometer. Below is a partial listing of mercury free thermometers that EHS stocks for exchange. Please contact EHS for assistance with replacing manometers or thermometers not on the list.
Thermometers have nonhazardous, biodegradable liquid and dye. Dark green liquid color makes them easy to read and different in appearance from all other non-mercury thermometers. Accuracy is equivalent to mercury thermometers of the same type and range. All thermometers have permanently-fused markings, and all but 200mm (77/8") length thermometers have unique serial numbers for ISO 9000 or other quality systems. A statement of accuracy is provided to indicate instrument traceability to standards provided by the National Institute of Standards and Technology and Deutscher Kalibrierdienst (DKD). Instructions for reuniting the liquid column are included with each thermometer.
