In modern industrial and environmental monitoring, real-time monitoring of aerosols (such as dust, smoke, etc.) is crucial. As an efficient and accurate monitoring tool, the DustTrak™ Aerosol Monitor can help users grasp the aerosol concentration in indoor and outdoor environments in real time to ensure a safe and healthy working environment.

To help you get the most out of your DustTrak™ and extend its life, we have compiled the following seven tips to help you better maintain and use this instrument.

Tip 1: Follow the manual carefully

Always use the DustTrak™ Aerosol Monitor according to the instructions in the manual.

The manual details the instrument's operating procedures, precautions, and maintenance methods. Following the instructions in the manual can avoid instrument damage or data deviation caused by improper operation. Whether it is your first time using or you use it daily, the manual is your best reference.

Tip 2: Regular factory cleaning and calibration

Return the instrument to the factory annually for cleaning and calibration to obtain optimum performance.

Regular cleaning ensures the accuracy and reliability of the instrument. Regular professional maintenance can remove dust from inside the instrument, calibrate the sensor, and avoid performance degradation due to long-term use.

Tip 3: Perform a zero-point check before use

Perform a zero-point check before each use.

The zero-point check is an important step to ensure that the instrument readings are accurate. For continuous monitoring, an auto-zero module is recommended to eliminate drift caused by changes in temperature, humidity, or aerosol deposition in the optical chamber. This step can significantly improve the reliability of monitoring data.

Tip 4: Cleaning and maintaining the impactor

Clean all DustTrak II impactors (PM1/PM2.5/PM4.0/PM10) and add impactor oil before each use.

Also, clean the Dorr-Oliver 10 mm nylon cyclone separator to ensure it is functioning properly. Refer to the DustTrak manual for the use and cleaning procedures of the inlet regulator. Cleaning and maintenance of these parts will prevent clogging by particulate matter and ensure smooth airflow and accurate monitoring data.

Tip 5: Battery management

When the instrument has not been in use for a long time (>30 days), please charge it and remove the battery.

The battery is a key component for the normal operation of the instrument. When not in use for a long time, removing the battery can prevent battery leakage or damage. At the same time, regular charging can extend the battery life and ensure that the instrument can be started at any time when needed.

Tip 6: Replace HEPA filters regularly

Replace the DustTrak monitor's HEPA filter according to the instructions in your manual.

HEPA filters are used to block large particles from entering the instrument, protecting sensors and internal components. Regularly replacing filters can ensure smooth airflow and avoid monitoring errors caused by filter blockage.

Tip 7: Use the correct inlet tubing

For the inlet tubing, use only the conductive silicone tubing provided with the instrument, and keep it as short and straight as possible (no bends or kinks).

The quality and installation method of the inlet tube directly affect the airflow's stability and the accuracy of the monitoring results. Using non-conductive tubes or curved pipes may cause static electricity accumulation or poor airflow, thus affecting the monitoring data.

By following these seven tips, you can ensure your instrument always operates in top condition, extend its lifespan, and reduce the frequency of maintenance and repairs.
