The OctTemp is an eight channel thermocouple data logger with a reading rate of up to 4Hz. It can measure and record 500,000 readings per channel. To maximize memory capacity, users can enable or disable channels. For easy identification, each channel can be named with up to a ten digit title. In addition, the OctTemp features individual cold junction compensation for each channel providing increased accuracy and response time, and if a probe is removed or severed during logging, the software automatically annotates the data. The OctTemp is ideal for a variety of applications, whether it is remote temperature monitoring, or multiple points in a central location. The OctTemp comes with a wall mounted 120VAC/9VDC power adapter. Note: European customers should choose the OctTemp-EU model under the ordering information. This model includes a wall mounted 230VAC@50Hz/9VDC power adapter. Thermocouple probe sold separately.
