One use

The electrode is composed of PH glass electrode and the reference electrode combination in the composite electrode together, it is a sensor used to measure the pH, the concentration of H in aqueous solution (PH), widely used in various fields for detection of PH. The electrode you buy is a precision analysis of test sensor elaborate, after a comprehensive test before the products leave the factory, carefully follow the following instructions such as user operation and maintenance, can obtain the best test effect and prolongs the service life of the electrode. The electrode from the Shanghai science and technology limited company 021-65895299 magnetoelectric sub production and supply

Three. Working environment

1.The ambient temperature is 5-40 degreesTwoRelative humidity: less than 85%

Four. Use, maintenance and precautions

1.Before test, take off the electrode protecting sleeve (the solution is 3MKCL, if there is the exudation of the crystal, it is normal, does not affect the use of electrode)2.Observe whether the inside of the sensitive bulb is full of liquid. If the bubbles are found, the electrode should be moved gently downward (like a thermometer) to remove bubbles in the sensitive bulb, otherwise it will affect the accuracy of the test

Five. The electrode and the pH meter calibration and testing facilities

1.The PH electrode is connected to the input of the PH instrument, and the connection is correct. Calibration is carried out according to the instruction of the instrument, and the result shall be measured after calibration

Six. Preservation and maintenance of electrodes

1.The electrode uses an electric gap. Please clean the electrode with distilled water. Then dry and put it in a protective bottle and be injected with solution before the next test

2.If the electrode is not used for a long time, it should be rinsed and sucked away the residual distilled water

3.The sensitive glass bulb at the front of the electrode can not contact the hard material, and any breakage and wiping will cause the electrode to fail

FourThe electrode has been used for a long time, the electrode slope and response speed or reduced. The measurement can be soaked in 4%HF end electrode for 3-5 seconds or dilute HCL solution with distilled water after 1-2 minutes, wash in potassium chloride (4M) solution for the new complex

5.The measured container such as pollution sensitive global ball or blockage of the liquid junction material to electrode passivation phenomena, the response speed was slow, the slope decreases or reading instability, so it should be based on the nature of the pollutant, choose appropriate cleaning solution, the new pollutants and appropriate cleaning agent. Please refer to the next table

 

Contaminants

Cleaning agent

Organometallic oxide

Lower than /M HCl

Organic lipid substances

Dilute soap or detergent

Resins, polymers, Jing substances

Ethyl alcohol acetone ether

Protein corpuscles

Acid enzyme solution

Dyes

Dilute bleach liquid hydrogen peroxide

SixIn order to measure the organic solvent that can dissolve the carbonic acid resin, please choose the glass shell type electrode (such as E-314 type composite electrode) in PH composite electrode
