Overview
YKF200 ultra-low temperature platinum resistance thermometer
Product Details
YKF200 is a miniature thermometer with a temperature range covering from -260 ℃ to 260 ℃. The thermometer features a special design, with a gold-plated copper shell filled with dry helium gas. The sealed part is treated with special techniques to ensure that helium gas does not leak. This model of thermometer has excellent long-term stability and repeatability, and can be used as a reference thermometer for ultra-low temperature calibration. It is a designated product of the National Institute of Standards and Technology (NIST) in the United States.
