The MT-530Ri plus temperature and humidity controller measures relative humidity from 5 percent to 85 percent without condensation, and temperature from 14° to 158°F (–10° to 70°C). Its outputs are independent, which allows it to be configured as a two-step humidistat. Its temperature and humidity sensors are joined in a unique bulb, which reduces the space needed for the installation's wiring. The instrument also has serial communication for connection with the Sitrad via internet software, which allows online management of the installations from anywhere in the world.
