Description
THC Analyzer meets all current regulations for the measurement of THC, including UN-ECE. R.49 and US EPA 40CFR, Part 1065. It has been packaged to survive the harsh environmental conditions of in-use testing.
Feature
- Automatic Flame Ignition: The FID flame will light automatically after approximately 30 minutes of warm-up time.
- Measuring Range: The SEMTECH FID has 4 user-selectable measurement ranges between 0-100 and 0-30000 ppmC1.
- Sample Handling: A water trap and Nafion dryer are integrated into the SCS module. A heated sample line (various lengths) delivers the sample to the FID chamber at 191°C. Particulate matter is removed using a built-in disposable filtering system.
- Combustion Air: The system includes a catalytic converter, enabling the use of room air as combustion air for the FID flame.
- Compliance: The SEMTECH FID is compliant for gases regulated under the rules of UN-ECE. R.49 and Commission Regulation (EU) No. 582/2011 and of US EPA 40CFR, Part 1065.
- Heated Lines: Sensors has developed an innovative, low powered heated line that controls and maintains the temperature of the exhaust sample at 191 ± 5 °C.
- 12V DC Power: The system operates on 12V DC power.
