Waterproof 2. salinity meter test pen automatic temperature compensation (ATC) 3. Large screen display resolution and high precision 4. 5. Simple, sturdy and durable 6. unique angular design with non-slip function Operation: 1. Remove the protective cover. 2, wash with water electrode (electrode cap surrounding a white crystalline salt, which is normal, as long as the electrode is immersed in water to dissolve disappear). 3,? ON / OFF "tap on the switch panel, turn on the power. 4, insert the measured liquid salinity meter, until the liquid dipped slightly submerged bottom line. Conditions allow, enable solution dipped slightly submerged line location. 5, gently stir until the value is stable, read the display. 6, after use, turn off the power, clean the electrode with water, put on protective sleeve. used in laboratories, field and schools fast, accurate . The test applies to the brine salinity, pool, aquaculture, aquarium (sea) and ponds, food processing and health care industries Note: 1, has been used (or place) for a long time after calibration 2, the use of special electrodes. frequently. 3, the measurement accuracy requirements are relatively high. 4, the calibration with new buffers. 5, can not let the bubbles on the electrode measurement, otherwise it will affect the measurement results. 6 and can not adjust the instrument, the instrument has been used for a long time only After the goods replace the electrode should be recalibrated. 7, in case of indication error, showing the value of the beating, showing the value is not zero and so on, should be inserted in the following parts of the instrument immersion line quickly shake alcohol to clean the sensor. pen factory before commissioning, can be used directly, PH pen all need some time to re-commission (usually 3-4 months to see the frequency of use) Battery Installation: When replacing the battery, unscrew the cap on the circle, pull the battery compartment to replace, Note battery polarity electrode replacement: If clicking cleaning and calibration instruments, the value of the measurement error is large, you should replace the electrode, unscrew the next round lid, pull out the electrodes, unplug the plug electrode, the electrode can be replaced with new. Note: To install the new electrode waterproof rubber ring, ensure that the instrument's waterproof battery, unscrew the cap on the circle, pull the battery compartment to replace, pay attention to the battery polarity electrode replacement: if clicked, cleaning and calibration instruments, value measurement error is large, you should replace the electrode, unscrew the next round lid, pull out the electrodes, unplug the plug electrode, the electrode can be replaced with a new Note: To install the new electrode waterproof rubber ring, waterproof guarantee instrument .
