便攜式氧分析儀DF130E
Accuracy: (at constant conditions)
Standard Models: the greater of +/-3% Reading or 0.5% of Range
High Resolution Models: the greater of +/-3% of Reading or
0.02% of Range (except for the 0- 100 ppm range: the greate
+/-3% of reading or 50ppb; for the 0-50 ppm range: the
greater of +/-3% of reading or 10ppb)
微量氧氣分析儀DF-130E系列
