笔式PH操纵阐明

笔式PH是接纳很新微功耗积体电路设计,功能良好,普遍使用于理化剖析,环保,餐饮,化装品,水族馆,养殖业,无土种植…等等行业。

好处: 技能功能:

•全防水,IP67品级。 •丈量范畴:0~14pH

•可改换电极。 •准确度:±0.1pH

•超大荧幕表现。 •情况温度:0℃~50℃

•携带笨重。 •电池:纽扣电池1.5V×3

•仪器尺寸:170mm×37mm×37mm

• 仪器毛重:80g

仪器校准:翻开PH笔顶盖,调校调治器

1. 将笔式PH电极放入PH7.0的缓冲液中,调校左边调治器,使仪器表现为7.0。

2. 将笔式PH电极放入净水中洗濯。

3. 将笔式PH电极放入PH4.0的缓冲液中,调校右边调治器,使仪器表现为4.0。

维护:

笔式PH在出厂时已校准,可间接利用。(临时久置不必,请于利用时重新校准)

丈量后,笔式PH电极使用洁净水洗濯。

当仪器表现屏变暗时,请改换电池及留意电池正负极偏向。

利用:

1. 将笔式PH电极掩护盖取下,翻开电源开关。

2. 笔式PH电极放入测试液体中,仪器便会表现正确PH读数。

3. 丈量终了,封闭电源,套上电极掩护盖。

PH PEN/Tester Operation Manual

PH PEN/Tester adopted with latest micro-electronic circuit design, to provide high performance, steady and accuracy measurement. This PEN is widely applies in work of chemical analysis, environmental protection, food, hygiene, aquaculture and horticulture, etc.

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

If the instrument has not been operating for a long time, it should be recalibrated before use.

Usually clean the electrode with distilled water after use.

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.
