The “Joint International Symposium on Temperature, Humidity, Moisture and Thermal Measurements in Industry and Science” – TEMPMEKO - ISHM 2025 is one of the most important international scientific events held every three years under the auspices of TC12 IMEKO – International Measurement Confederation and CIPM Consultative Committee for Thermometry Working Group Humidity.

The first Symposium took place in Karlove Vary, Czechoslovakia, in 1981. The latest was held in Chengdu, China in June 2019.

The next editions of the International Symposium on Temperature and Thermal Measurements in Industry and Science (TEMPMEKO) and the International Symposium on Humidity and Moisture (ISHM) are both scheduled to be held in 2025. Over the past forty years, attendance has grown appreciably, and the Symposium now attracts in excess of 400 delegates from more than 45 countries.

The Symposium TEMPMEKO - ISHM 2025 will be held in Reims, France between the 20th and the 24th of October 2025.
The Symposium’s main aim is the exchange of information and views among the members of the international scientific community, professional metrologists, manufacturers of measurement equipment, engineers and students working in the field of thermometry, humidity and thermophysical quantities.

NCSL International is a member based, volunteer driven, professional trade organization. NCSLI recognized the need to provide excellent opportunities for the world’s measurement science professionals. Today, this continues to be achieved by expanding the knowledge and skills of our members by exchanging information and promoting measurement education, through our support of conferences, training events, committees, communities and professional industry standards. NCSL International membership in open to any organization or individual with an interest in metrology “the science of measurement” and its application in research, development, education, commerce.

SENSOR+TEST is the world's leading forum for sensor, measurement and testing technology.

When SENSOR+TEST – the leading international trade fair for sensor, measuring and testing technology – opens its doors again in Nuremberg on Tuesday, 6 May 2025 under the motto "Welcome to the Innovation Dialog!", visitors can expect three days of pure technology with innovations to touch.

Until 8 May 2025, exhibitors will inform visitors and experts from all over the world on site about the trends in the industry. The exhibition will become even more attractive because an exciting supporting programme will be compiled.

The SMSI 2025 - Sensor and Measurement Science International Conference will take place parallel to the exhibition and will enrich the event with scientific facts and outlooks for the future of this industry.

The CIM is the premier event where metrology intersects with science, industry and quality infrastructure organizations. RH Systems is looking forward to seeing you there!

This 22nd edition promises another dynamic 4-day program, featuring parallel sessions tackling global challenges. 100% in english, with over 200 presentations covering oral and poster sessions, along with round tables, workshops, a short course and a variety of social events, the CIM continues to be a hub of cutting-edge discussions and networking opportunities.
