Why Does a Type K Temperature Probe Become Less Accurate Over Time ?
13/08/y 14:41:25

A Type K temperature probe may gradually become less accurate after prolonged use due to aging, oxidation, and changes in the probe’s thermoelectric characteristics. The higher the temperature and the longer the exposure time, the more noticeable these effects can become.

Can a standard meter measure such a very small current?
12/08/y 10:58:58

Multimeters can still measure small currents, but only up to a certain limit. When the current drops to the µA or nA range—or lower—the device's resolution, background noise, and stability begin to directly affect the results. This is when a picoammeter or a specialized current-measuring instrument is required
