Factors affecting the quality of anchor tray determinations(1) Environmental temperature change, due to thermal expansion, the balance of the unequal arm and other reasons, will make the balance of the zero point and the equilibrium point of change, the value of the occasional deviation can be up to a number of times the balance of the sensibility. Thus, the balance room should be a constant temperature, first-class, second-class standard balance and first and second-class laboratory balance should be 20 ℃ ± 2 ℃ under the conditions of work, the accuracy of a little lower to reach 20 ℃ ± 5 ℃.
