TEMPERATURE AND HUMIDITY DIGITAL
CONTROLLER WITH SERIAL COMMUNICATION
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
via Internet.
Product complies with UL Inc. (United States and Canada).
Producto de conformidad con CE (Unión Europea) y UL Inc. (Estados Unidos y Canadá).
