There is no shortage of temperature probes out there, and the most accurate of all is the platinum RTD probe. But, converting the resistance of platinum to an actual temperature is unusually complicated. Fortunately, the Atlas Scientific EZO-RTD Circuit makes taking high accuracy readings from a platinum RTD probes easy. The EZO-RTD Circuit can work with any class of 2, 3, or 4 wire platinum RTD probes and has a sensing range of -126.000 °C to +1,254 °C.
