The transmitter is easy-to-use and easy to install. The GMT220 series transmitters have a modular structure, which includes a separate mounting plate that eases the installation.

Since the probes of the transmitter are truly interchangeable, they facilitate the field maintenance. The probes can either be replaced by newly calibrated probes or separate ones that can be used as reference probes for calibration checking. This minimizes the downtime and eliminates the need for expensive calibration equipment.
