The resistance accuracy is up to 1%. It comes with very short response time. Similar to ATH10KR8, ATH10KR8B series also has three version...(more)
TEC modules ( thermoelectric coolers ) are designed for cooling and heating, depending on the direction of direct current. When the current flows from the negative direction to the positive direction, TEC will start to cool, and conversely, it will start to heat. TEC modules have been widely used for controlling the temperature of laser system, refrigerator cooling system, air conditioner, computer CPU and so on. The physical photo of TEC module Our company has researched and developed TEC modul...(more)
