TC202 temperature controller

TC202 is a classic temperature controller, which supports resistance thermometers such as platinum resistance and rhodium-iron, and can realize heating control of up to 50W within the temperature range of 1.4K~450K. TC202 has a serial port, which can be used to communicate with a computer, and can be used in conjunction with eastchanging's Liquid Nitrogen Thermostat to stably generate any temperature between 80~300K, with an error of ±0.1K or less. ±TC202 is a complete function, easy to use, inexpensive, and a very cost-effective product of eastchanging.


Performance and features
