Specification
PID Instrument — Less than 20 seconds for 90% of final value, using
100 ppm of isobutylene
FID Instrument — Less than 20 seconds for 90% of final value, using
10,000 ppm of methane
PID Instrument — Less than 20 seconds to return to 10% of original
value, using 100 ppm of isobutylene
FID Instrument — Less than 20 seconds to return to 10% of original
value, using 10,000 ppm of methane
Auto Mode — 1 per second to 1 per 999 minutes, user selectable
VOC or FE Mode — 2 to 30 seconds, user-selectable
1 liter/minute, nominal, at sample probe inlet
The battery can be fully charged in less than 16 hours. The battery
operating time is 8 hours minimum at 20° (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.)
The battery charger is a separate unit 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 operate battery charger in an area classified as
hazardous due to presence of flammable gases or vapors.)
Greater than 2000 hours for 10.6 eV lamp, with normal cleaning
Greater than 2000 hours
Greater than 75 dB at 3 feet
Pressure — 15.3 MPa at 25°C (2200 psi at 77°F) maximum
Empty — 85 cc (5.19in 3 )
Greater than 8 hours of continuous operation, starting from a
cylinder charged up to 15.3 MPa (2200 psi)
The analyzer enclosure and front panel are made from a chemically
resistant thermoplastic material. The approximate dimensions are
343 x 262 x 81mm (13.5 x 10.3 x 3.2 in). The enclosure is designed
to provide environmental protection.
