DH-20 circulating constant temperature bath adopts a microcomputer intelligent control system. Equipped with a circulating pump, it can draw the constant temperature liquid in the bath to establish a second constant temperature field. It is widely used in research departments, universities, enterprise quality inspection and production departments, such as petroleum, chemical, electronic instruments, physics, chemistry, bioengineering, medical and health, life sciences, light industry and food, physical property testing and chemical analysis, etc., providing users with a liquid environment with controlled temperature and uniformity. The fluctuation is selectable between ±0.05℃ and ±0.1℃. The LED dual-window red and green lights display dual-color digital display, and a large-screen LCD display can also be selected. The touch soft key can quickly set the temperature, and the operation is convenient. The microcomputer corrects the deviation of the temperature measurement value, and the temperature digital display accuracy can be selected as 0.1℃ or 0.01℃. It has an over-temperature alarm system. |
