Item # 402 Series, Automatic Sequencer


The 402AS Automatic Sequencer allows a single Nova gas analyzer to be time shared between 3 to 24 sampling points. This greatly reduces the cost per sampling point for multiple-zone analyses.
The 402AS consists of microprocessor based timing, a solenoid valve for each point and a by-pass pump. The by-pass pump continuously draws on all sample points so as to keep fresh sample always available for analysis. Unwanted sample points can simply be skipped over. Also, the timer can be stopped on any one point and held there for as long as desired with a simple key press. A small keypad allows easy data entry.
If purchasing Model 402AS, please specify method of sample stream identification : 5V TTL, contact closure, or RS-485 output.
