TEMPERATURE CONTROLLERS - N321, N322 and N323 INTRODUCTION The N321 / N322 / N323 temperature controllers present state-of-the-art technology, specially developed for matching the needs of the freezing and heating markets. They include jacks for Pt100 and Pt1000 type temperature sensors, NTC thermistors, or J/K/T type thermopairs. They are low-cost, easily assembled equipment, resulting in an excellent process optimization. CE (European Union) and UL (United States and Canada) certifications compliant.
