OT-WK100 Intelligent Temperature Controller

The instrument uses an advanced microcontroller as its control core and is equipped with high‑performance imported temperature and humidity sensors. It can simultaneously measure and control temperature and humidity signals and provides digital display functionality.
Upper and lower limits for temperature and humidity can be configured via buttons, enabling the instrument to automatically activate fans or heaters based on real‑time environmental conditions, thereby regulating the actual temperature and humidity of the monitored environment.
Operating status is indicated by two green LEDs, enhancing intelligent operation and enabling the instrument to adapt to complex and variable field conditions, effectively protecting equipment.
This instrument is suitable for various cabinet types, including high‑ and low‑voltage switchgear, terminal boxes, and box‑type substations.
