Fits multi-type thermocouple temperature work where you need an Extech TM100 supporting K/J/T/E/R/S/N with Type K to 1372 °C and ±(0.15% of reading + 1 °C) class accuracy.
Key advantages
- Types — K, J, T, E, R, S, N
- Type K range — −200 to 1372 °C (−328 to 2501 °F)
- Type J range — −210 to 1100 °C
- Accuracy — ±(0.15% of reading + 1 °C) class
- Functions — Max/Min/Avg; differential where supported
Typical applications
- Multi-type TC field measurements.
- Process temperature surveys.
- Differential T1−T2 checks.
Selection guide
- TC type — Match probe metallurgy
- Range — High-temp R/S vs K
- Differential — Dual-input needs
- Probe connector — Mini-TC compatibility
Common mistakes
- Wrong TC type selected vs probe.
- Open-junction errors without secure connector.
- Ignoring cold-junction context on fine work.
