笔式PH计的操作说明
在实验室中，对于一些精度要求不高的情况，我们可以考虑使用笔式PH计，笔式PH计是采用很新微功耗积体电路设计，性能优越，广泛应用于理化分析,环保，食品，化妆品，水族馆，养殖业，无土栽培…等等行业。
优点： | 技术性能： |
·全防水，IP67等级。 | ·测量范围：0~14pH |
·可更换电极。 | ·精确度：±0.1pH |
·超大荧幕显示。 | ·环境温度：0℃~50℃ |
·携带轻便。 | ·电池：纽扣电池1.5V×3 |
·仪器尺寸：170mm×37mm×37mm | |
· 仪器净重：80g |
仪器校准：打开PH笔顶盖，调校调节器
1. 将电极放入PH7.0的缓冲液中，调校右边调节器，使仪器显示为7.0。
2. 将电极放入清水中清洗。
3. 将电极放入PH4.0的缓冲液中，调校左边调节器，使仪器显示为4.0。
维护：
l PH测试笔在出厂时已校准，可直接使用。（长期久置不用，请于使用时重新校准）
l 测量后，电极应用干净水清洗。
l 当仪器显示屏变暗时，请更换电池及注意电池正负极方向。
使用：
1. 将电极保护盖取下，打开电源开关。
2. 将电极放入测试液体中，仪器便会显示准确PH读数。
3. 测量完毕，关闭电源，套上电极保护盖。

Instrument Calibration
1. Soak the electrode in 7.0pH/4.0pH solution. If the display does not show the right pH value, adjust the unit to the right measurement. (Remove the protection cap and adjust the knob. Right knob for 7.0pH / Left knob for 4.0pH).
2. Clean the electrode with distilled water.
3. Soak the electrode into buffer solution at 4.0pH. If the display does not show the right pH value then adjust the left point to make it displays 4.0pH.
4. If it is necessary please repeat procedure 1. to 3.
Maintenance
l If the instrument has not been operating for a long time, it should be recalibrated before use.
l Usually clean the electrode with distilled water after use.
l Replace the batteries when the display became dim.
Operating
1. Remove the protection cap and turn on the power.
2. Place the electrode in sample solution until the result show on the display.
3. Turn off the power, clean the electrode and cover the protection cap after test.
