Cold Junction
+/-0.1 C thermistor; NIST-traceable class
Fits four-type thermocouple calibration where you need a PIECAL 322 sourcing and reading J/K/T/E plus mV with ±(0.008% of reading + 0.006 mV) accuracy and ±0.1 °C cold-junction class.
Key advantages
- Types — Source/read J, K, T, E plus mV
- mV range — −13.000 to 80.000 mV
- Accuracy — ±(0.008% of reading + 0.006 mV)
- CJC — ±0.1 °C thermistor; NIST-traceable class
- UI — Graphic LCD with backlight; auto steps/ramp; 4× AA ~50 h
Typical applications
- Four-type TC transmitter checks.
- mV instrument simulation.
- Field TC source/read rounds.
Selection guide
- Four-type vs 14-type (422)
- Step/ramp — Auto sequences
- CJC accuracy — Fine work
- Leads — Mini-TC compatibility
Common mistakes
- Wrong TC type vs probe.
- Open connector CJC errors.
- Buying 322 when 14-type 422 is required.
When to RFQ / what to tell us
- Leads; quantity; ship-to.
