AccuSafe - For continuous gas monitoring at one or more points

Click Picture for Larger AccuSafe Unit Image

Interscan’s AccuSafe takes the familiar “Point sensor reporting to a controller” design approach to the next level.  AccuSafe consists of up to ten sensor modules reporting to a single controller.  Since the communications are Modbus TCP/IP, there is no limit on the distance between sensor modules and the controller.

What’s more, each sensor module is provided with an integral sample draw pump, for a quicker and more reliable response.  And, data acquisition is built right in.  No additional software is needed. Temperature and relative humidity sensors are also included.

Get Safe with AccuSafe, the new generation of Continuous Gas Monitoring systems.

There is not a separate analyzer available for each of these compounds, and the sensor does not respond equally to all hydrazine species. The analyzer must be calibrated with the specific hydrazine compound of interest.
