为了消除汞害,进一步提高航空仪表的检定或校准精度,航空工业部组织了压力测试无汞化的技术攻关。根据无汞压力计通用技术条件,我厂研制了取代汞柱压力计的标准无汞压力测试设备。现有LPH-2无汞压力计、LPH-2J无汞绝压计,业经部三○四所鉴定合格,正式投产使用。部属厂、所也购用了我厂研制的无汞设备。
In order to eliminate mercury damage and further improve the verification or calibration accuracy of aviation instruments, the Aeronautical Industry Ministry organized a technical study on mercury-free pressure testing. According to the general technical conditions of mercury-free pressure gauge, our factory has developed a standard mercury-free pressure testing equipment to replace the mercury column pressure gauge. The existing LPH-2 mercury-free pressure gauge, LPH-2J mercury-free absolute pressure gauge, the Ministry of Industry identified three four four, formally put into operation. Subordinate factory, also purchased by our factory developed mercury-free equipment.
