Accumac / Probe /AM1612 Full Immersion PRT

AM1612 Full Immersion PRT

· Temperature Range: -196°C to 180°C

· Accuracy ±0.05°C

· Transition junction and lead wires can withstand full PRT temperature range

AM1612 full immersion PRT is uniquely designed to provide users an excellence temperature probe that can expose the transition junction and lead wires to an environment that covers the full PRT temperature range. The seal of probe prevents the ingress of moisture so that the probe can work in a humid condition or even under full immersion in common heat transfer fluids such as ethanol, silicone oil and mineral oil.

AM1612 is small in size with probe length of 50 mm and diameter of 3 mm. A unique assembly procedure provides the best balance among the hysteresis effect, mechanical shock and thermal shock performance
