Four-Channel Thermometer (309 DATALOGGER)

This instrument is a four-channel digital thermometer with any K-type thermocouple as the temperature sensor. Temperature indication follows the National Bureau of Standards and IEC584 temperature/voltage table for K-type thermocouples. Its internal memory can keep up to 16,000 records per channel. It uses an RS232 interface to perform bi-directional communication with the PC. In some applications, the temperature is concerned at more than two points. This is why we provide the four-channel model thermometers 304 and 309. The operation interface is intuitive, and all the temperature data are shown on the LCD at the same time so that there is no extra step for the user to get the reading. Numerical Display: 4 digital Liquid Crystal Displays per channel.
