Building upon the success of the Vulcain 90DM3A, Vulcain is proud to introduce the newest refinement in infrared carbon dioxide detection, the Vulcain 90DM4. The Vulcain 90DM4 improves upon the Vulcain 90DM3A’s reliable dual sensing technology by offering better drift, temperature and humidity compensation, in addition to a redesigned enclosure built to enhance airflow, and an improved backlit display (optional).
Installation, connection and use of the Vulcain 90DM4 are virtually identical to the Vulcain 90DM3A. With the same state-of-the-art microprocessor controlled CO2 monitoring coupled with refined performance, the Vulcain 90DM4 is the top choice for monitoring CO2 levels in schools, offices, or any other commercial application.
