flash pointMaintenance and upkeep of analytical instrumentsHow important is it really

When operating, it is necessary to strictly follow the procedures, strictly follow the precautions, preheat the instrument before use, and do a good job of post cooling or cleaning. Otherwise, no matter how well maintained the instrument is, it will never be durableSo, in other wordsIt is very important to establish a comprehensive maintenance system for analytical instruments.

Reasons for recommending the Beijing Times New Wei fully automatic flash point tester series:

Under the conditions specified in the national standard GB/T 3536, the instrument places the sample into a test cup and heats the test cup containing the test oil. The low temperature at which the condensed synthesis gas formed by the petroleum vapor and the surrounding air ignites upon contact with the flame is used as the flash point. The instrument controls the heater based on the collected temperature changes, causing the temperature of the test oil to rise at a certain rate. When the flash fire is measured, the instrument stops data collection, displays the flash fire temperature, prints the recorded results, stops heating, and the test arm automatically lifts, ending the experiment.

Precautions

• The instrument should be used in a non corrosive environment. When replacing the sample, the oil cup must be cleaned.
• When the instrument is not in use, it should be placed in air with a temperature of 10-40 ℃, a relative humidity of below 80, and In an environment free from corrosive gases and harmful substances.
• When conducting experiments, the instrument should be placed in a fume hood that can independently control the airflow
• If too many samples are injected into the sample cup, a pipette or other appropriate tool can be used to remove them; If the sample comes into contact with the outside of the instrument, the sample should be poured out, the sample cup should be cleaned, and the sample should be refilled.
• Ensure no air leakage before the experiment.
