Value
The 330 measures H2S in natural gas or other process streams. The unit has dual 4–20 mA outputs, dual measurement alarms, plus trouble and fault alarm relays. An external magnetically-driven interface allows operator functions without opening any covers. The 330 displays H2S concentration in user specified units and as well will auto range to 5 times the lower calibrated range. Calibration is performed manually via the operator interface or automatically when connected to a calibration bottle with the optional auto calibration solenoid. The 330 is available with a number of optional sample systems and accessories to handle various applications such as high range H2S, Total Sulfur or H2S in liquids.

Lead Acetate Sensors: Lead acetate is essentially interference free from other sulfur compounds. This is why it is used by the vast majority in the industry when accurate measurement is required. The linear output enables the user to perform a single point calibration.

Longest Tape Life: The 330 offers the longest tape life in the market by using a proprietary tape advance algorithm to make complete use of the 300 foot tape. The unit will accept up to a 350-foot roll. Envent sensing tape is the strongest in the market.
