PHOTOMULTIPLIER:

The detection system uses a photomultiplier tube R-372 (20362-01) as standard equipment. For increased infrared response (>700nm), the optional photomultiplier tube (20368-09) is available. The r-955 phototube has a wide spectral range: from arsenic at 193.7 nm to cesium at 852.1nm.

Video Display: All instructions and messages are displayed on a 15 x 18 cm cathode ray tube (CRT)

Microcomputer:

Retention of memory even when power button is turned off.
Automatic calibration and zero functions.
Format lock switch.
Restart/standby switch
Battery ON
CRT "cookbook" display

NOTE: Baud rate is factory se at 1200 for the high rate and 300 for the low rate.

OPTIONAL COMPONENTS:

Automatic Wavelength Drive
Deuterium Arc Background Corrector compensates for non- specific molecular absorption and/or light scatter.
RS232C Interface allows output of the information presented to the optional printer to another computer via and RS232C communications port.
Four-lamp Turret with independent power supplies for each lamp, replaces the single lamp mount.
Flame Sensor supplements the standard safety features of ou AA system, which includes the following:
Gas pressure sensors to safely extinguish a flame if pressure begins to fall.
A safety drain trap that never needs filling
A frangible diaphragm that protects the operator in case of a flashback; when activated, the flame sensor will automatically shutdown the flow of flammable gases if the flame is extinguished for any reason.
