Three Measurement Devices Research Projects of Zhejiang Institute of Metrology Accepted Acceptance

[China Instrument Network Instrument R&D] Recently, Zhejiang Institute of Metrology assumed the "Research on conductive liquid medium thermal conductivity test device", "Study of portable blackbody metering furnace based on semiconductor technology", "Portable temperature and humidity standard device based on splitting method "Research" and other three scientific research projects passed the acceptance of the Provincial Bureau of Quality Supervision.

"The study of conductive liquid medium thermal conductivity test device" developed a transient hot wire thermal conductivity test device, with the characteristics of stability, small fluctuations, etc., can be used for rapid measurement of conductive liquid medium thermal conductivity, to fill the material heat Physical property key laboratory in the liquid phase thermal conductivity test blank.

Based on the research of portable blackbody metrology furnaces based on semiconductor technology, a portable blackbody metrology furnace device based on semiconductor technology was developed and developed. It features high emissivity, rapid temperature rise and cooling, and portability, and will provide more convenient and efficient services for on-site inspections.

The "Research on Portable Temperature and Humidity Standard Devices Based on Shunt Method" solves the problem of temperature and humidity parameters, develops a high-precision portable temperature and humidity standard device, and has the characteristics of simultaneous control and simultaneous measurement of temperature and humidity parameters in the same cavity. , It can be used as a new supporting equipment for laboratory metrology standards to improve the laboratory's online testing and calibration capabilities.
