Introduction; Precautions; Initial Inspection - Campbell TEMP 120 Product Manual

1. Introduction

The TEMP 120 is a 20-channel thermocouple measurement module. For sensor connections it
offers universal type miniature thermocouple jacks. An individual reference junction temperature
sensor is located at the base of every connection. Since the device is purpose built, is uses a
simplified data logger measurement instruction and computes the compensated temperature
on-board rather than relying on a data logger to make the calculation.
