The Extech TM500 is a professional 12-channel thermocouple datalogger that supports six thermocouple types (J, K, E, T, R, S) for simultaneous multi-point temperature monitoring. It displays channels 1–8 or 9–12 on-screen, logs all 12 channels to a removable SD card in Excel® format, and features user-programmable sampling (1–3600 sec), Min/Max, Data Hold, offset adjustment, and manual storage of 99 readings. Ideal for thermal chamber analysis, quality control, HVAC, refrigeration, automotive testing, and oven core monitoring. Supplied with 8 AA batteries, 12 Type K bead wire probes (TP873), an SD card, and a hard carrying case.
