土壤酸鹼度計與溼度計使用方法 DM 15 Takemura Electric Works Ltd., Japan
這是日本 Takemura Electric Works Ltd 出的儀器,雖然使用上有一些限制,但在田間非常好使用,不需麻煩要帶樣土回去檢測,直接可以讀取數值,可快速測試田間各點的土壤,,這型號還有測式溼度功能,可決定是田間是否要供水,使用上有一些要注意,不然很容易就壞了,如果好好正確使用,可以用十年以上。
DM-15 土壤酸鹼度計與溼度計特性規格如下:
實現快速簡單的方法來獲得準確的價值。
將金屬電極插入地面,可以立即測量pH和含水率
不需要化學工具測量。
測量pH範圍為3-8的土壤pH值,精確率為0.2pH。
水分含量:1-8%。
尺寸:48(寬)x 48(高)x 160(長)毫米。
重量:135克。
產廠說明:
If the soil to be test is dry or contains much manure, the meter will not indicate a correct ph value, therefore, sprinkle about a bucketful of water on the soil, and wait 20-30 nimutes, before testing.
Before using the meter, be sure to throughly polish its metallic surface with a piece of wetting cloth or sandpaper. When using a brand-new meter, be sure to insert in into the soil a few time in order to remove the oily impurities from it’s metallic surface.
Insert the meter directly into the field or paddy soil under consideration. Completely embed the metallic surface and tamp down the surrounding soil so that it adheres closely to the meter’s metallic electrode surface.
About one minute after insertion the meter in the soil, the pointer will cease to deflect-the value of the soil may then be read.
the meter may sometimed register different values depending on soil condition, such as, adhesion to teh meter’s metallic surface, moisture content, or the amount of manure it contains. it is therefore ideal to make an average of several measurements.
In order to determine whether or not liming has been properly done, after one or two weeks mix the soil well and measure is pH value.
翻譯如下:
1.如果測試的土壤乾燥或含有大量的肥料,儀器不會顯示正確的pH值,因此,在土壤上撒上一桶水,等待20-30分鐘,然後再進行測試。
2.在使用儀器之前,一定要用濕布或砂紙徹底拋光金屬表面。當使用一個全新的儀器,一定要插入土壤幾次,以除去金屬表面的油性雜質。
3將儀器直接插入的田間或水稻土壤中。土壤完全嵌入金屬表面,使其緊密粘附在儀器的金屬電極。
4將儀器插入土壤後大約一分鐘,指針停止偏轉 ,然後讀取土壤的值。
5根據土壤條件(例如對金屬表面的附著力,水分含量或其含有的肥料),測量儀可能會記錄不同的值。因此平均進行多次測量是理想的。
6為了確定土壤是否進行適當石灰處理,要在一至二個星期後土壤充分混合後測量
使上上注意事項:
1.不要嚴重摔到機器
2.不適合測量溶液與堆肥
3.土壤積水不適合使用
4.不可用水沖(探頭不可水洗)
5.溼度7%以下讀值是正確的
6.使用完最好放入防潮箱
拿葡萄風信子來測試
土壤含水量為 3%
