MODEL 306 DUAL CHANNEL DATALOGGING THERMOMETER
1
1.0 Introduction:
This instrument is a dual channel, recording digital thermometer for use with any Type K
thermocouple as a temperature sensor. Temperature indication complies with the NIST and
IEC584 temperature/voltage tables for Type K thermocouples. Its internal memory can store up
to 16312 records in any number of recording intervals. It is equipped with a RS232 interface for
bi-directional communication with a PC.
