Tips

For best accuracy, ensure the probe tip is fully immersed in the medium and allow a few seconds for thermal equilibrium. The 4-wire connection minimizes lead resistance errors, making this probe suitable for high-precision applications. Avoid bending the cable sharply near the probe to prolong its life.
