In recent years, he worked with senior senior engineers of the China Institute of Metrology to compile the "Glass Liquid Thermometer" and the "Common Data Table for Alcohol Density Concentration and Temperature Conversion", and participated in revising the "Verification Regulations for Petroleum Special Thermometer", "Verification Regulations for Standard Glass Thermometer" and "Verification Regulations for Working Glass float Meter" compiled by the National Metrology Institute. Cooperated with the State Administration of Quality Supervision, Inspection and Quarantine to carry out the action of "Paying attention to people's livelihood, Measuring and benefiting the people", and participated in the compilation of the Selection and Use of Thermometers. In the book "Physical property Analysis Instrument" published in 2005, the factory has a comprehensive introduction. For more than 40 years, Yaohua Factory has been committed to the production, research and development of temperature detection equipment and temperature measurement, force and density meter standard instruments. The products have been widely used in petrochemical, wine, measurement, scientific research, coal and other fields.

The main products are:

First, the laboratory with standard verification tank, economic constant temperature tank, high product accuracy, good stability.

Second, sub-standard densitometer, sub-standard alcohol meter, one, two standard densitometer, petroleum densitometer, seawater densitometer, coking densitometer, alcohol meter, sugar content meter and various work with glass float meter, etc.

3. Metal fixed point container devices (gallium, indium, tin, zinc, aluminum, silver, copper) and water triple point bottles, glass floats, standard thermometers of first and second class, special thermometers for petroleum, coking, meteorological, brewing and working thermometers, hygrometers; In particular, the special thermometer for brewing industry solves the product pollution in the process of brewing and food production, and can effectively avoid food quality accidents.

4. Special flotation meter for brewing industry: 1, first and second class standard alcohol meter, precision and working alcohol meter; 2, wine production for the Rusak sugar liquid meter; 3, dedicated to fruit wine, rice wine production of 0-40%v018 composed of alcohol meter; 4, dedicated to the production of liquor 30-65%vol 7 composed of a set of alcohol meters.

5, precision digital thermometer wide range, high accuracy, strong stability, easy to operate. It can be widely used for temperature field inspection in laboratory, test room and production process.

Solemnly promise: where "Yaohua" products are tested by the metrology department, if there are unqualified products rechecked, the factory bears the verification fee.

Tips: You can not choose "Yaohua" products, but be sure to choose qualified measuring instruments.
