Product Introduction:
This series of ultra high precision constant temperature baths is developed to meet the extremely high requirements for constant temperature accuracy in various metrology, electronics, chemical, environmental protection, medicine, energy, refining, metallurgy, light industry, military and other departments and research institutes. After years of independent development, the integrated intelligent instrument temperature control is more accurate. In addition, the uniquely designed non heat centrifugal circulation pump makes the flow field and temperature field inside the bath turbulent and highly uniform. At present, the performance of the ultra-high precision constant temperature bath has reached the international leading level, and its biggest highlight is the digital display resolution of up to 0.0001 ℃. Our company has become the largest manufacturer of constant temperature baths in China. This device is widely used as a calibration standard in the manufacturing of various thermometers, various types of thermistors, and other temperature measuring instruments. It can also be designed as an automatic detection and sorting device. This product is also known as: high-precision standard constant temperature bath, high temperature standard calibration constant temperature oil bath, low temperature calibration standard constant temperature bath, thermometer calibration bath, measurement specific constant temperature bath

◎ Humanized R-rounded design structure for front panel and countertop to avoid scratches
◎ External circulation function: The centrifugal jet circulation pump can draw out the constant temperature liquid in the tank, establish a second constant temperature field, and control the external experimental container of the machine
Internal circulation function: Adopting a non heat centrifugal circulation pump to avoid the influence of traditional water pumps on the tank temperature field due to their own heat generation. The internal circulation system is designed based on the principle of porous U-shaped reflux circulation, achieving turbulent and highly uniform flow and temperature fields inside the tank
