GLT portable VOC analyzer organic volatile gas detector

We have launched GLT-VOC700 to address the diversity and complexity of measuring VOCs GLT portable VOC analyzer organic volatile gas detectorPID can facilitate customers to detect the required areas at any time, with high accuracy, fast response, and high stability. It has a wide range of compatible expansion interfaces and can be configured with a variety of sampling extension rods according to different customer needs, suitable for different environments!

2、 Industry Applications

The current national standards for VOCs are mainly concentrated in industries such as petrochemicals, chemicals, oil storage and transportation, plastic, rubber, leather products, as well as social services, furniture, and batteries. Local standards are mainly distributed in industries such as biopharmaceuticals, automotive painting, and printing. As of this year, there are currently 76 organic pollutant projects.

4、 Principle

The PID photoionization detector uses a vacuum ultraviolet lamp (UV) with a specific ionization energy (such as 10.6eV) to generate ultraviolet light. When organic gas molecules bombard gas molecules in the ionization chamber, the organic molecules contained in the gas are ionized and broken into positively charged ions and negatively charged electrons. Under the electric field of the polarizing plate, the ions and electrons collide with the plate, forming a detectable weak ion current.

The gas around the air is extracted into the system through an extraction pump, impurities in the air are filtered through a micro filter, water vapor is removed through a micro water barrier, and finally enters the detector for analysis to remove impurities and the impact of water vapor on the sensor, ensuring measurement accuracy.

6、 Design Basis

The composition of VOC gas is relatively complex, and each enterprise has different operating conditions. Designing a suitable system according to different operating conditions is necessary for accurate and stable operation!

4.3-inch touch screen, good operating environment. It has functions such as manual zero calibration, parameter setting, reporting, alarm, system settings, etc.

Operation menu: Calibration function, communication function, instrument status information, unit, range setting and other functions.

Manual zeroing: The instrument can be manually zeroed. Inject pure air or nitrogen for one click calibration. Calibration OFF: When the analytical instrument measures multiple parameters, perform full point calibration on each parameter.

Report: The instrument has the function of querying historical data in reports.

System settings: Set the screen backlight to adjust during daytime or nighttime use; Screen saver time, when measured continuously for a long time, can screen saver the screen and extend battery life.
