| Accuracy |
±25% of reading or ±2.5 ppm, whichever is greater, from 1.0 to 10,000 ppm. Accuracy listed is achieved using methane with a 1-point calibration in the range from 100 to 500 ppm (including drift) at the temperature and humidity of the calibration. |
| Repeatablility |
±2% at 100 ppm of methane |
| Analog Output |
Two analog output signals, 0 to 2 dc, proportional to the count output from each detector. |
| Dynamic Range |
1.0 to 50,000 ppm of methane |
| Linear Range |
1.0 to 10,000 ppm of methane |
| Minimum Detectable Level |
The minimum detectable level is defined as two times the peak-to-peak noise.
300ppb of hexane |
| Response Time using close area sampler |
Less than 3.5 seconds for 90% of final value, using 10,000 ppm of methane |
| Recovery Time using close area sampler |
Less than 5.0 seconds to return to 10% of base line, using 10,000 ppm of methane |
| Response Time using telescoping wand extender |
Less than 5.0 seconds for 90% of final value, using 10,000 ppm of methane |
| Recovery Time using telescoping wand extender |
Less than 5.0 seconds to return to 10% of base line, using 10,000 ppm of methane |
| Response Time using charcoal filter adapter |
Less than 20 seconds for 90% of final value, using 10,000 ppm of methane |
| Recovery Time using charcoal filter adapter |
Less than 20 seconds to return to 10% of original value, using 10,000 ppm of methane |
| Data Storage Rate |
From 1 per second to 1 per 999 minutes, user selectable |
| Sample Flow Rate |
1 l/minute, nominal, at sample probe inlet |
| Battery |
The battery can be fully charged in less than 16 hours. The battery operating time is 8 hours minimum at 32°F. Use of the backlight on the probe display shortens battery life. The battery is replaceable by removing the bottom cover of the instrument.
(WARNING: Do not replace battery in an area classified as hazardous due to presence of flammable gases or vapors.) |
| Battery Charger |
The battery charger is a separate unit designed to be mounted on a table top. It is capable of operating the analyzer while simultaneously charging the internal battery. An adapter cable is provided to charge the battery separate from the analyzer. The charger can charge a fully discharged battery in a maximum of 16 hours. Charging takes longer if performed while the instrument is operating. Two types of chargers are available, one for 120 V ac 50/60 Hz and another for 230 V ac, 50/60 Hz.
(WARNING: Do not replace battery in an area classified as hazardous due to presence of flammable gases or vapors.) |

| Enclosure Description |
The analyzer enclosure and front panel are made from a thermoplastic material. The approximate dimensions are 343 x 262 x 81 mm (13.5 x 10.3 x 3.2 in). The enclosure is designed to provide the environmental protection of NEMA Type 3R (rain, snow, and sleet). |
| Electrical Interface Connections |
Mating female connectors for Analog Output, RS-232 Interface, and Battery Charger are provided on the side of the analyzer case below the keypad. |
| Mechanical Connections |
Mechanical connections for Sample Input and for Vent Outlet are provided on the side surfaces. |
| Portability |
The analyzer is designed to be carried by a removable shoulder strap. The strap, which is provided with every instrument, does not hinder the user when viewing or using the analyzer front panel. The strap is designed to support the probe when the instrument is not in use. |
| Transportation Case |
A specially designed thermoplastic case is provided for transporting the analyzer and all of its accessories in a personal vehicle or common carrier. It is of rugged construction and is fitted with shock and vibration absorbing material. |
| Tool Kit |
An accessory tool kit is provided with each instrument. The kit contains special tools for accessing the battery and removing the detector capsule. |
| Approximate Mass |
