The Model 4020 uses a field-proven FID detector to measure THC in various streams. This instrument is ideal for monitoring hydrocarbon contamination in high purity bulk gases. When coupled with Teledyne’s unique separation column, the 4020 is also diverse enough to be applied in hazardous locations for detection of volatile hydrocarbons in cooling water for process leak detection and environmental compliance.
- Easy-to-use front panel interface with red 5-digit LED display and a vacuum fluorescent display (VFD), driven by microprocessor electronics
- High resolution, accurate readings of concentration
- Versatile analysis with three user-definable analysis ranges
- Microprocessor based electronics
- Two adjustable concentration alarms and a system failure alarm
- Extensive self-diagnostic testing at startup and on demand
- RS-232 serial digital port for use with a computer or other digital communication device
- Analog outputs for concentration and range identification (0-1 VDC standard and isolated 4-20 mA dc)
| 4020 Total Hydrocarbon Analyzer | Uses FID to measure total hydrocarbons in ppm in a sample gas stream |
| 4030 Total Hydrocarbon Analyzer | Basic 4020 with sample system at a higher temperature for heated applications
Avoids condensation of the sample |
| 4040 Methane / Non-Methane | Basic 4020, plus temperature-controlled sampling system with GC column to give accurate readings of both methane and non-methane hydrocarbons in a gas stream |
| 4060 Benzene Analyzer | Same as 4040, but used to measure ppb levels of benzene instead of methane/non-methane |
| 4080 Total Hydrocarbon Analyzer | Basic 4020 with sample system including stripper to measure total hydrocarbons in an aqueous sample |
