EBTRON ADVANCED THERMAL DISPERSION TECHNOLOGY
EBTRON pioneered bead-in-glass thermistor-based thermal dispersion over 40 years ago. EBTRON’s thermal dispersion technology relates the power dissipated by a self-heated thermistor to the airflow rate at one or more sensor nodes in an airstream. All EBTRON airflow monitoring systems use this time-tested thermal dispersion technology.

MODEL DESCRIPTION
The GTx116e-P is EBTRON’s top-of-the-line airflow monitoring system that also provides velocity-weighted temperature and optional velocity-weighted psychrometric measurements, thus providing a turn-key solution for today’s high-performance buildings. Multiple sensor nodes provide accurate measurements of critical airstream parameters. Unsurpassed connectivity options and a “no-compromise” design makes this your best choice for today’s high-performance buildings.
