NiloTech PT125 Digital Cryo Temperature Probe

The Nilotech PT125 is a NiloChecker-compatible immersible thermal probe designed for use in cryopreservation environments. Built around an analog PT100 sensor, the PT125 is accurate within ± 0.1 °C across a temperature range from –200 °C to +50 °C. The probe’s tip is 150mm in length, making it easy to position in an open vessel, and 1.6mm in diameter, minimizing heat transfer; the attached Teflon cable allows the probe to be fully immersed in large dewars. The sensor’s accuracy and reliability, and the probe’s design and construction, make the PT125 suitable for both quick level control spot-checks and for long-term monitoring.
