I-NSEN yasekwa ngo-1983, igxile kwicandelo leevalvu zeebhabhathane ezingaqhelekanga. Emva kweminyaka yophando kunye nokusebenza, uthotho lwemveliso ekhoyo ngezantsi luye lwenziwa:

• Ivalvu yebhabhathane engaqhelekanga kathathu
• Ivalvu yebhabhathane esebenza kakuhle
• Ivalvu yebhabhathane esuka kwisinyithi iye kwisinyithi
• -196℃ ivalvu yebhabhathane ekhazimlayo
• Ivalvu yebhabhathane yokukhusela umlilo kubushushu obuphezulu
• Ivalvu yebhabhathane elithambileyo
• Ivalvu yebhabhathane enganyangekiyo emanzini olwandle

Kwicandelo lobungcali, gxila kwiivalvu zeebhabhathane. I-NSEN ikwaphucula rhoqo izakhono zayo kwaye ibonakalisa amandla ayo.
