TECPEL
This product is designed for general water quality measurement and is not suitable for measuring chemical raw materials, special solvents and other liquids. The
sensing electrode may be damaged by such liquids or cause large errors.
Do not measure anything with strong stickiness, such as glue, ink and other liquids, because the sensor head of this instrument is very fragile, if it is slightly
pressed or knocked, it may cause damage to the hard head.
Under no circumstances should this instrument be in direct contact with food or drinking water, etc. Please use a
measuring cup to scoop up a sufficient amount of liquid, and then insert the instrument into the measuring cup to measure.
Before using the product, please be sure to understand that if the instrument measures strong acid (below pH 4) or strong alkali (above pH 10) liquid, the service
life of the instrument will be greatly shortened, and it will cause direct damage to the electrode head and make it impossible to measure.
If the KCL liquid or pH7 calibration liquid accidentally touches the eyes, mouth, etc., please rinse with plenty of water! If you still feel uncomfortable after
washing, please send to the doctor immediately and take the accidentally contacted liquid to the hospital.
The accuracy of the instrument will increase due to factors such as battery power attenuation and electrode aging. If you need more accurate measurement, it is
recommended to use pH7 calibration liquid to calibrate before each measurement to confirm whether the error is within the specification. Measurement is performed
after the test is performed. For detailed calibration methods, please refer to the calibration operation instructions in the manual.
Please place the instrument in a place that is difficult for children to take, so as to prevent children from eating or damaging the instrument by mistake.
Please keep the KCL liquid in the electrode protective sleeve, and do not fill it with general tap water or mountain spring water.

3. Use distilled water or pure
water to clean the electrode
head, try to avoid using
general tap water or river
clean water to clean the electrode head.
4. Pour an appropriate amount of pH 7 calibration solution
into the measuring cup, the liquid height is
enough to cover the front end of the electrode tip.
5. Insert the dried electrode into the measuring
cup
and wait for about 10 seconds for the value to
stabilize.
The battery needs to be replaced regularly. If the battery power is low, the error of the measured value will increase.
6. If the measured value is not equal to 7.00, use the adjustment pen
to fine-tune the adjustment knob on the right side of the
instrument, so that the value on the screen is displayed as 7.00.
1. For the first use, please insert the battery and turn on the power. 2. Open the protective cover, then stretch the electrode, and then remove the
latex
protective cover of the electrode.
If you do not use the instrument for a long time, please remove the battery, and make sure that there is enough KCL liquid in the latex protective case. Crystal particles
will form after KCL is placed for a long time. This is normal, please don’t worry.
When measuring any strong acid or strong alkali liquid, please clean the electrode tip and wipe the instrument with a neutral liquid. Do not use it in liquid with strong
adhesion, such as ink. Because the electrode tip is quite fragile, it is not suitable for contact. Touch clean and wipe with a cloth.

7. After the adjustment is completed, clean
the
sensor head again.
8. Start measuring the liquid to be tested.

measurement outside the specification), natural disasters and earth-changing damages are not subject to this limitation
(if service is required to replace parts, the parts fee will be charged according to the price specified by the company).
(2) The chargeable service period is one year: within one year after the free service period is exceeded, if the product fails to
be
repaired and replaced with parts, the parts fee will be charged according to the price stipulated by the company, and the
service fee will be charged as appropriate.
2. If the invoice is lost or there is no certificate, the company will use the factory date of the manufacturing number
3. Guarantee content:
(3) If the product has been used for more than the above two years, if it fails and the company still has parts, it will
provide
service, but the service fee will be charged in addition to the parts fee. If the company has no parts, it will be difficult to
service.
1. This product is guaranteed for one year from the date of purchase, but the aging of the electrode head and the use of
related
calibration fluids are not covered by the warranty.
