PH type E-331C sensor:

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 prolong the service life of the electrodes.

Model and main technical parameters
1 measurement range: 0 ~ 14pH

2 applicable temperature: 0 ~ 60

300 points: the theoretical slope (PTS) = 98.5% (25 C)

4 zero pH value: 7 + 0.25pH

5: the internal resistance is less than or equal to 250M (25 C).

6 base error: less than 15mV (25 C)

7 response time: less than 2S (25 C)

8 size: 12 x 120 (mm).



work environment

1 ambient temperature 5-40 degrees

2 relative humidity: less than 85%

Use maintenance and precautions

1 before the test to take off the protective sleeve of the electrode, the solution is 3MKCL, if there is a crystal exudation, which belongs to the normal phenomenon, does not affect the use of electrodes

2 observe whether the sensitive bulb is full of liquid, if it is found that there are bubbles, then the electrode should be gently swing (like a swing body thermometer), in order to clear the bubbles in the sensitive bulb, otherwise it will affect the accuracy of the test.
