The Yocto-PT100 is a USB temperature sensor. This is the most accurate USB temperature measurement device that we offer. The module uses an external PT100 probe (not included) to make instant temperature measurements, and can also record measures on a built-in flash memory to read them later on through USB. A PT100 probe is used to measure the temperature at any specific place, including in a liquid, with a very high stability and a high accuracy(sensibility up to 0.01Ѓ and accuracy up to 0.03Ѓ at 0Ѓ when using a PT100 conforming to IEC 60751 DIN 1/10 B standard). It is particularly well suited for applications such as laboratory measurements, etc.

The Yocto-PT100 can be used with PT100 probes using 2, 3 or 4 wires. The type of connection is setup in software. To reach the highest accuracy, a 4-wire probe should be used. 3-wire probes are reasonably accurate and not too much affected by wire lengths, contrarily to 2-wire probes which are the least accurate and very sensitive to wire length.

The Yocto-PT100 features a built-in galvanic isolation between the USB control part and the PT100 measure circuit. It is therefore possible to use non-insulated PT100 probes, which are often more reactive and less expensive,

Given the number of variants of PT100 probes and their prices, the Yocto-PT100 does not include any probe. The probe must be purchased separately at a specialized shop.
