Integrated Multi-parameter Sensor Operation manual

65

7.

Tighten the diaphragm. Then slowly rotate the electrode and make the head of electrode down toward.

This process can eliminate the bubbles in the head. Swing the electrodes vertical downward slightly.

Make sure the head of electrode down toward in the process of swing, and do not swing too hard.

Otherwise, the cap of electrode will be damaged.

7.2 Sensor Storage

7.2.1 Short Storage

Short term refers to the intermittent period (days, weeks, two weeks, etc.) in which the host is in normal

use.

For short-term storage users should keep the sensor moist, but do not immerse in water (immersion in

water can cause the sensor to drift). The user should place it in a humid saturated air environment (100%

humidity). Inject approximately 1 cm of water into the bottom of the calibration container (note: never

immerse the sensor), then insert the sensor-equipped main unit into the calibration container and tighten

to prevent evaporation of the water.

7.2.2 Long-term storage

Long-term refers to the state of being unused for a long time.

1)

For long-term storage of the pH sensor, remove it from the main unit, clean it, and then immerse it in a

protective cover with 3.0 mol/L potassium chloride solution, pay attention to tightening.

2)

For dissolved oxygen sensors, due to their intrinsic properties, there are two methods for long-term

storage:

A.

Keep it on the main machine and immerse it in water. Tighten the calibration container to prevent

evaporation. When the storage is finished, you should re-exchange the film to use it. This article

recommends using the method.

B.

Remove the sensor from the main unit, immerse the probe in the water, do not damage the membrane

or the probe tip when putting it into the bottom, and check the water level regularly. When the storage is

finished, it must be replaced again before it can be used. The interface end should be protected with a

plastic bag.

3)

The other sensors are removed from the main unit, the sensor is cleaned, and it is recommended that
