NM-03 Automatic Freezing and Storage Device of Water Triple-point Bottle
Product Overview
NM-03 Automatic Freezing and Storage Device for Water Triple-point Bottle is special measuring equipment successfully developed by our company with advanced automation technology according to the latest demand of the measuring industry. This device has two major functions: firstly, as a special device for water triple-point bottle freezer, it can automatically complete the procedures of cooling, freezing and heat preservation; secondly, it can be used as a high-precision low-temperature thermostatic bath. The equipment can automatically complete the freezing process according to the corresponding temperature curve and give a manual prompt signal; it can also automatically complete the system protection according to the set upper and lower limits of temperature to prevent accidents.
