Transmitter M100 2XH NPT
Small Footprint for Hazardous Areas. The M100 HM is a single-channel, multi-parameter transmitter that is mounted directly over the sensor electronics via an NPT ¾" connection. It is compatible with pH/ORP, pH/pNa, oxygen and conductivity sensors and supports HART communication.
Designed for Challenging Environments
The M100 is an explosion proof/flameproof transmitter with intrinsically-safe electronics providing accurate measurement in hazardous
Predictive Maintenance
Access to ISM predictive diagnostic tools available over HART leads to reduced maintenance and increased process uptime.
Plug & Measure Operation
With iSense software, sensors can be calibrated via a PC or mobile device, then connected to the M100 without the need to recalibrate.

Intrinsically Safe Design
The M100 HM is designed to be mounted directly to the sensor. The stainless steel housing is explosion proof/flameproof and the electronics are intrinsically safe, providing a safe, accurate measurement.
Integration & Control via HART
The transmitter configuration and integration of sensor diagnostics into asset management tools is possible thanks to the integrated HART protocol. This ensures maximum compatibility and easy integration.
Small Footprint
The M100 HM is mounted directly on the head of the sensor, and has neither a local display or operator interface. This provides for a compact measurement point that can be installed in hazardous or non-hazardous areas.
