PTM1200 generation data loggers have six, 10 and 20 thermocouple channel variations. Two-way RF communications allows reset and download while the system is in the furnace. Additional features include: faster sampling rate – down to 0.2 seconds over the full 20-channel selection without any loss of accuracy; memory to 3.8 million data points, allowing high sampling rates even in long processes; and Bluetooth connection. The data-logger memory contains the latest calibration correction data as well as a signed copy of the original calibration certificate, which can be printed if required. The data can be transferred with a “click” into Thermal View software, saving manual input of the correction factors.
