Product Description: Khan Dayton think (HANDSON) Brand DL series, also called low-temperature circulating pump cryogenic cooling water circulation pump, low temperature cooling liquid circulating pump, air-cooled refrigeration compressor imported closed and computer intelligent control system to provide low-temperature circulating cooling water ( liquid) flow or low temperature water (liquid) stream to meet the cooling water and the cryogenic liquid to cooling or isothermal instrument, a chemical reaction under operating multi temperature and storage of drugs, such as with a rotary evaporator to the fermentation tank, electron microscopy, low-temperature chemical reactor, electron spectrometer, mass spectrometer, densitometer, freeze dryers, vacuum coating apparatus, reactor and other ancillary uses. The volume can be directly on the various experiments cryostat tank, often called "low-temperature cooling water circulation pump", also known as: "cryogenic pump", "low-temperature circulating pump", "cryogenic cooling circulating pump" and the like. Widely used in petroleum, chemical, pharmaceutical, life science, measurement, light industry, and research and other fields. Product Features: [1] instrument work area with high-quality stainless steel, anti-rust, anti-corrosion, anti-low pollution. [2] opening large capacity external circulation bath and body, can be cooled or heated machine outside the test vessel a second temperature field. [3] After the computer has a sleep timer, turn this feature off timer can be set from 0 to 100 time in hours. [4] fully enclosed air-cooled refrigeration compressors, refrigeration microcomputer intelligent control system automatically turns on, the cooling system has a delay, overheating, over-current protection devices such as multiple. [5] uses the double window, red, green, two-color LED display temperature settings and temperature measurements, digital resolution of 0.1 ℃, microcomputer temperature measurement error can be corrected to make digital accuracy of 0.1 ℃. [6] with computer software lock function, you can lock each parameter setting system, unrelated persons can not change the set parameters. [7] All of the above operations are pressed on a microcomputer intelligent control device touch softkey is complete, the product easy to use, can work continuously.
