Kingdder Liquid Nitrogen Measuring Stick Ruler Reads 1-56cm Precise Cryogenic Depth Gauge for Dewars, Containers, and Storage Tanks

Features: Cost savings: avoid waste caused by excessive evaporation of liquid nitrogen and extend the service life of equipment. Size and Length: there are scales ranging from 1 to 56 cm, suitable for most liquid nitrogen tanks. Specifications: Material: plastic Color: black Size: 56 cm in length Package includes: 1 X liquid nitrogen ruler Notes: Manual measurement, please allow slight errors on size. The color may exist a slight difference due to different screen displays.

• Precise Liquid Level Measurement: by taking advantage of the boiling point characteristics of liquid nitrogen, the depth of liquid nitrogen is directly indicated by the frost formation range on the surface after the measuring ruler is inserted into the liquid nitrogen tank, without the need for complex electronic devices
• Three-step Operation: first, insert it into the bottom of the liquid nitrogen container, then stand still for 1 minute, and finally take it out to observe the frosty area; No professional training is needed; Laboratory personnel and low-temperature storage managers can quickly get started; Non-contact measurement, does not damage the liquid nitrogen container structure, and does not affect the purity of liquid nitrogen and storage environment
• Durable Material: low temperature resistance, the main body of the measuring ruler is made of ultra-low temperature material resistant to -196°C, to avoid cracking or deformation, ensuring long-term use stability; Special surface treatment, reduce frost residue, easy to clean and reuse after multiple measurements
• Safe and Reliable: avoid blind fluid replenishment: through precise liquid level monitoring, prevent excessive liquid nitrogen overflow or shortage, ensure the safety of equipment and personnel; Reduce waste caused by excessive evaporation of liquid nitrogen, and reduce laboratory or industrial storage costs
• Wide application scenarios: meet the needs of multiple industries, biomedicine: liquid nitrogen level monitoring in cell banks, vaccine storage, low-temperature laboratories, etc.; Industrial manufacturing: liquid nitrogen cooling processes such as semiconductor processing and superconducting material preparation; Scientific research and education: liquid nitrogen management in low-temperature experimental equipment in university laboratories and scientific research institutions
