| Chlorine ion concentration, % | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 |
| 0.040 | It is brick-red | It is brick-red | It is brick-red | It is brick-red | It is brick-red | It is brick-red | It is brick-red | It is brick-red | It is brick-red | It is brick-red |
| 0.045 | It is brick-red | It is brick-red | It is brick-red | It is brick-red | Yellow | Yellow | It is brick-red | It is brick-red | It is brick-red | It is brick-red |
| 0.060 | Yellow | Yellow | It is brick-red | Yellow | Yellow | It is brick-red | It is brick-red | Yellow | It is brick-red | Yellow |
| 0.075 | Yellow | Yellow | Yellow | Yellow | Yellow | It is brick-red | Yellow | Yellow | Yellow | Yellow |
| 0.080 | Yellow | Yellow | Yellow | Yellow | Yellow | Yellow | Yellow | Yellow | Yellow | Yellow |
A. during chloride ion content=0.045, it is 80% to judge result accuracy,
B. during chloride ion content=0.075, it is 90% to judge result accuracy.
Conclusion：The utility model chloride ion content higher than setting limitation 25% or less than setting limitation 25% when,
There is preferable judgement accuracy, and device experiment result overall stability is preferable.
This experiment setting limitation is using GB 14684-2011《Construction sand》The limitation 0.06 of middle three classes sand.
2. the deviation of 32 sand loading volume of back-up sand cylinder
The deviation that same 10 dresses of sand take is 14.96%,
The deviation that 10 dresses of different fineness sand take is 23.49%,
The deviation that same 10 dresses of damp sand take is 38.92%,
Conclusion：Take the deviation of sand smaller for dry sand device dress, by taking 25% deviation as an example, setting limitation is 0.06
When, deviation range is between 0.045~0.075 or acceptable.The deviation of damp sand is larger, so suggesting using this dress
It puts and dry sand is used when simply to judge.
(dry sand：Moisture content≤5%, damp sand：Moisture content ＞ 5%).
