Honeywell Analytics Multipoint Sample Draw Gas Monitor SQN8X

Honeywell Analytics Multipoint Sample Draw Gas Monitor


The Honeywell Analytics SQN8X is a sample draw gas monitor. The standard unit (SQN82) has two sampling points and a three-relay output for different stages of alarm. The unit is ideal for MRI rooms as the sampling point tubing can be up to 1000' from the monitor. The optional two-gas model will pick up both gases at each sampling point. Each unit includes 100 ft lengths of sampling tubing per number of ports ordered. The SQN8X Multipoint Sample Draw Gas Monitor is designed to be used as part of a control system that helps to prevent the formation of a hazardous environment when properly installed and maintained.
