When the screen displays low power, please replace the battery in time.<br/>2. The water used to prepare PH6.86 and PH9.18 solutions should be boiled 15-30 minutes in advance to remove dissolved carbon dioxide. During cooling, avoid contacting with air to prevent carbon dioxide pollution.<br/><p><br/></p><p><b>How to Use:</b></p>1. In order to ensure the accuracy of the measurement results, please be sure to clean the PH electrode before starting the measurement, first clean with distilled water, and then clean with the solution to be tested; When measuring, it is necessary to put the PH electrode into the solution to be measured, shake it several times, and then stand for 3‑4 minutes before reading, the PH measurement error is within the range of ±0.05PH, during which the value fluctuation within the error range (the last decimal point beat) is normal; If there is a large fluctuation after 3‑4 minutes, the reading time can be extended, the instrument will automatically shut down within 4 minutes without key operation, restart and continue to observe the value change, and the value will continue to be the value before shutdown after starting. <div>2. Instrument calibration: The instrument needs to calibrate PH4.00 and PH9.18 points before use, please configure the calibration liquid of the two calibration points in strict accordance with the instructions, please measure the temperature of the calibration liquid with a thermometer before starting calibration and set the temperature to the measured temperature, the greater the temperature error, the more inaccurate the calibration will be, resulting in inaccurate measurement results, and then start the formal calibration operation.</div><p><br/></p><p><b>Package List:</b></p>1 x HT-1202 PH Meter<br/>1packet x PH4.00 Standard Buffer Reagent<br/><div>1packet x PH9.18 Standard Buffer Reagent<br/></div><div>1packet x Potassium Chloride Powder</div><div>1 x Electrode Soaking Liquid<br/></div>1 x PH Non-chargeable Combination Electrode<br/>1 x Manual<br/>1 x Black Case</div><br/><p><br/><br/><br/><br/><br/><br/><br/><br/><br/></p></div></div></div>
