- Pull or push mode gas streams
- Linearized mass flow meter
- Variable drive diaphragm pump
Description
The SS-4-Sampler unites a pump, needle valve and linearized mass flow meter into a tough, compact instrument. Its individual gas ports can be used alone or in any combination, making it a versatile solution for sampling or sub-sampling in almost any gas analysis application.
The SS-4 is designed for pushing or pulling a gas stream through one or more gas analyzers. Usually this sample gas stream is sub-sampled from a source with a higher flow rate.
The linearized mass flow meter covers the range from 0 to 2000 ml/minute, with flow rate displayed on the two-line alphanumeric display. The high quality diaphragm pump provides quiet operation adjustable over a wide range using PWM (Pulse Width Modulation) – minimizing power consumption and diaphragm wear, and lengthening pump motor life.
Five analog output ranges are selectable from easily accessed menus on the device or via RS-232 commands. And due to Sable Systems’ open serial protocol, the SS-4 is easily integrated into any data acquisition setup whether digital or analog.
