The California Analytical Model 300HFID THC analyzer incorporates a heated flame ionization detector. The instrument, unlike most other THC analyzers, uses capillary tubes and electronic pressure controllers for gas pressure regulation. That means no more manual back pressure regulator! The instrument incorporates front panel diagnostics for troubleshooting. The instrument is set up for calibrations using propane gas standards, but can be re-optimized to calibrate using methane standards. Ranging is selectable from 10 ppm to 30,000 ppm.

Manufacture California Analytical Instruments Analysis Method Flame Ionization Detector Range 10 to 30,000 ppm Response Time 90% of full scale in 1.5 secs. Sample Flow Rate 3 liter/min. + 1.5 liter/ min. Noise Less than 0.5% of full scale Zero & Span Drift < 1% of full scale per 24 hours Analog Output 0 -10 VDC and 4 to 20 mA DC Power 115 VAC Dimensions 5 1/4?H x 19?W x 8?D Weight 38 lbs

The MSA Model 8800 THC analyzer incorporates a heated flame ionization detector. The instrument is microprocessor controlled and also uses capillary tubes for gas pressure regulation. Although the instrument incorporates a manual back pressure regulator, the regulator is highly accurate and does not require constant adjustment. The instrument incorporates front panel diagnostics for troubleshooting. Calibrations using either methane or propane are accomplished with the push of a button. Ranging is user-defined from 10 ppm to 100% (and linear above
30, 000 ppm!)

Manufacture Mine Safety Appliances (MSA) Analysis Method Flame Ionization Detector Range 10 ppm to 100% Response Time 90% of full scale in <10 secs. Sample Flow Rate 1 to 3 liter/ min. Zero & Span Drift +/- 1% per 24 hours Power 115 VAC Dimensions 9 1/4?H x 17.6?W x 16?D Weight 30 lbs

The California Analytical Model 300M HFID THC analyzer incorporates a heated flame ionization detector and a proprietary hydrocarbon cutter. The cutter responds to better than 90 % of the methane in a gas sample, while responding to less than 2% of the ethane and 0.1% of all other hydrocarbons. When in THC mode, the analyzer will respond to all hydrocarbons in a gas stream. In methane mode, the instrument will only respond to the methane in a gas stream. The non-methane content is the total hydrocarbon content, less the methane content. Ranging is selectable from 10 ppm to 30,000 ppm.

Noise Less than 0.5% of full scale Zero & Span Drift < 1% of full scale / 24 hrs. Analog Output 0 -10 VDC and 4 to 20 mA DC Power 115 VAC Dimensions 5 1/4?H x 19 "W x 8? D Weight 38 lb.

The Thermo Model 15 HCl analyzer uses a gas filter correlation / non-dispersive infrared detector. The gas filter correlation technique reduces instrument cross-sensitivity to similar gases. Calibration values are adjusted via the zero and span thumb wheels. The Model 15 offers ranging from 5 to 5,000 ppm.

Manufacture Thermo Environmental Instruments Analysis Method Gas Filter Correlation / NDIR Range 0 ? 5,000 ppm Linearity +/- 1% full scale up to 1000 ppm Zero Drift < 0.1 ppm in 24 hrs. Span Drift +/- 1% full scale in 24 hrs. Sample Flow Rate 1 liter / min. Analog Output Selectable voltage and RS232 standard Power 115 VAC Dimensions 16.75? x 8.62? x 23? Weight 45 lbs
