VOC concentration detector

Heating typeVOC concentration detector
The hydrogen flame ionization detector, which uses the entire measurement circuit heating type, is the latest VOC monitor. Due to the sample flow path being heated to high temperature for measurement (HOT FID), various T-VOCs can be quickly and continuously measured from low boiling point to high concentration, up to high boiling point. In addition, by using corrosion countermeasure type FID, it can also cope with the measurement of organic chlorine gases. In case of hydrogen flame extinguishing, the safety design automatically cuts off the hydrogen line, so you can use it with confidence.
The entire measuring flow path of this instrument is a heating type, equipped with a hydrogen flame ionization detector. Heat the sample airflow path to high temperature (HOT FID), from low concentrationLow boiling point to high concentrationHigh boiling point, capable of quickly and continuously measuring various T-VOCs. In addition, the use of anti-corrosion FID can also be applied to the determination of organochlorine gases. If the hydrogen flame stalls, the safety design of automatically cutting off the hydrogen flow path can be used with peace of mind.
Features:
1. High boiling point VOCs can also be stably and continuously measured, and data can be determined in a short period of time.
2. Equipped with anti-corrosion FID, it can continuously measure organic chlorine based gases.
3. Can be applied to emission management and control, explosion prevention, and other purposes.
