Mercury Thermometers & Alternatives in the USA

Thermometer Image: Courtesy FreeDigitalPhotos.net & mistermong USA — The USA’s National Institute for Standards and Technology (NIST) began an active mercury-reduction campaign in 2007, and stopped calibrating Mercury (Chemical symbol: Hg) thermometers entirely on March 1, 2011. A full range of thermometric calibration services continues for non-mercury devices according to the special NIST webpage at: www.nist.gov/pml/mercury.cfm Mercury is a potent neurotoxin, and every thermometer that contains it is a potential environmental threat. In the 21st century, however, that is a risk that no one needs to take, and a worldwide effort is underway to deploy substitute devices (alternatives) in consumer, … Continue reading

How to Make a Thermocouple Meter

With the LTC2492 –   featuring Mark Thoren, Linear Technology ,Applications Engineering Manager – Mixed Signal Products Thermocouples are perhaps the most common temperature sensor in use. While they are extremely simple and rugged, the output is very small. typically tens of microvolts per degree Celsius. Traditionally, thermocouple measurement circuits use a cold junction compensation circuit to drive the thermocouple negative terminal and a low offset amplifier with enough gain to use the entire input span of a 12- or 16-bit ADC. Linear Technology’s LTC2492 greatly simplifies thermocouple instrument design. A simple filter and protection circuit is all that is required … Continue reading
