Massa birligi milliy boshlang‘ich etaloni2
Massa birligi milliy boshlang‘ich etaloni namunaviy massa o‘lchovi majmuasi, tarozi va tarozi komparatoridan tashkil topgan, ushbu namunaviy vositalar 2000 yilda Shveytsariyaning «METTLER-TOLEDO» ishlab chiqarish qurulmalari laboratoriyasida tayyorlangan.
MBE tarkibiga:
- Tarozi komparatorlari АТ10005, АТ20005, AT 1006, АТ1005, АТ1004, РR1203, АТ200, PR5003, PR10003, КA30-3, AT 106H, UMT2, AT21, UMT5;
- Е1 aniqlik sinfidagi namunaviy massa o‘lchovlari: (1 ÷ 500) mg; (1
÷ 500) g; 1, 2, 5, 10, 20 kg.

Ishlab chiqarish faoliyati va fanning massani aniq o‘lchash natijalariga ehtiyojmand bo‘lgan sohalar:
- Asbobsozlik va mashinasozlik;
- transport;
- elektron va mudofaa texnologiyalari;
- tayyor mahsulotlarning hisobi va nazorati va boshqalari.
Topshiriq: Talabalar mustaqil tarzda adabiyotlat va Internet tarmog‘idan foydalangan holda chastota va vaqt birliklari milliy boshlang‘ich etaloni va massa birligi milliy boshlang‘ich etalonining vazifalari, metrologik xarakteristikalari va qo‘llanilish doirasi haqida yozma ma’lumot tayyorlashlari talab etiladi.
Takrorlash uchun savollar:
1. Ozbekiston respublikasining Milliy boshlang‘ich etalonlari haqida umumiy ma’lumnot bering.
2. Chastota va vaqt birliklari milliy boshlang‘ich etaloni qayarda tayyorlangan?
3. Chastota va vaqt birliklari milliy boshlang‘ich etalonining asosiy metrologik xossalarini aytib bering.
4. Chastota va vaqt birliklari milliy boshlang‘ich etalonining tarkibiga nimalar kiradi?
5. Massa birligi milliy boshlang‘ich etaloni nimalardan tashkil topgan?
6. Massa birligi milliy boshlang‘ich etaloninina asosiy metrologik xossalarini aytib bering.
