MODEL 314 DATALOGGING HUMIDITY TEMPERATURE METER Notes

1.0Introduction

This instrument is a dual channel, recording digital Humidity/Temperature meter providing simultaneous display of ambient humidity and temperature on the first channel, and a wide range temperature only measurement on the second channel. The first channel incorporates a polymer capacitive humidity sensor and a semiconductor temperature sensor (T1) in a detachable probe. The second channel employs a Type K thermocouple that complies with the NIST and IEC584 temperature/voltage tables for Type K thermocouples. The instrument’s 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.
