Palmer Wahl TM612A | Pocket RTD Thermometer | 0.02% Accuracy, USB, IP54
The TM612A is Palmer Wahl's RTD pocket thermometer, aimed at simplifying maintenance and commissioning of temperature transmitters and probes. It reads 2, 3 or 4-wire resistive probes, detecting the wiring automatically, through a Lemo 4-pin connector at 0.02% of reading. The datasheet lists platinum, nickel and copper sensor curves from Pt50 to Pt1000, Ni100 to Ni1000 and Cu10/Cu50.
