First there was the Ashcroft 2100E, then came the CPI TI-6000 followed by the Miljoco ED175-2403 "Little Red". Now the ev•o•lu•tion is now complete with the introduction of the Weiss 24DT. The "smart thermometer" features leave the competition in the dark ages. Features such as disconnectable sensor power, smart updates, °F/°C switchable and no more transformers, make the 24DT the new choice in LED temperature indicators.

American Heritage Dictionary defines: ev•o•lu•tion - The gradual
developement of something into a more complex or better form.
