Type K thermocouple. Type K thermocouples are low-cost, general-purpose thermocouples, made from chromel and alumel, operating in the -270°C to +1370°C temperature range. Sensitivity is approx 41 uV/°C.

Type N thermocouple. Type N thermocouples are made from nicrosil and nisil. The high stability and resistance to high-temperature oxidation of these thermocouples make them suitable for measuring high temperatures. They are less expensive than platinum types B,R, and S and were designed to be an improved type K.

Type R thermocouple. Type R thermocouples are made from platinum and rhodium, and are suitable for high-temperature measurements of up to 1760°C. Low sensitivity (10 uV/°C) and high cost make them unsuitable for general purpose use.

Type S thermocouple. Type S thermocouples are made from platinum and rhodium, and are suitable for high-temperature measurements of up to 1760°C. Low sensitivity (10 uV/vC) and high cost make these thermocouples unsuitable for general purpose use. Due to their high stability, type S thermocouples are used as the standard of calibration for the melting point of gold.

Type T thermocouple. Type T thermocouples are made from copper and constantan, are highly accurate, and operate in the -270°C to +400°C temperature range.

USB. Universal Serial Bus. This is a standard port that enables you to connect external devices to PCs. A typical USB 1.1 port supports a data transfer rate of 12 Mbps (12 megabits per second), and is much faster than a COM port.

USBTC08_INFO. This structure is used to receive information from the

usb_tc08_get_unit_info function and is defined in the usbtc08.h header file. Note: If the programming language you are using does not support structures, use the usb_tc08_get_formatted_info function.
