The XNX Universal Transmitter, now with HART
EDDL, marks a new turn in gas detection from
Honeywell Analytics. It supports the widest
range of sensors on a common platform and
offers a modular choice of inputs and outputs.

XNX is designed for flexible integration, simple installation, user-friendly operation
and straight-forward maintenance. It is ideal for use with a range of gas
monitoring controllers or industry standard PLCs. The introduction of our HART
Enhanced Device Descriptor Language (EDDL) software provides users with an
at-a-glance indication of the health of their gas detectors in the field.
