Full Gauge Controls MT-531Ri plus Quick Start Manual

1. DESCRIPTION
MT-531Ri plus is an instrument that indicates and controls the environment temperature and
humidity, indicated for low and average relative air humidity (from 20 to 85%, without condensation) and
temperature of -10 to 70ºC. Its sensors of temperature and humidity are joined in an only bulb, that
reduces the space in wiring of the installation.
The instrument has serial communication for connection with the
Product complies with UL Inc. (United States and Canada).
