Introduction
The THD200 is special for monitoring for strict indoor temperature and humidity control applications. It is an industrial class, high reliability, low-power consumption, high stability and high precision digital transducer.
The THD200 is used widely as a temperature and humidity measure of Laboratory, museum, warehouse, wareroom, storehouse, depot, depository, depositary, generator room, machine room, engine room, etc.
The THD200 with LCD, can be set temperature alarm threshold value, when the ambient temperature is lower than the Min. value or higher than the Max. value, the detector will be triggered and output one dry contact signal.
The THD200 with fire retardant shell, wall mounting makes it easy to install in fields.
Features
- High level precision temperature and humidity detector, LCD display, output dry contact signal;
- Easy to setup threshold value through buttons;
- Inspected by traceable standard, high precision and have function of procedure calibrate accuracy, low power consumption, high stability;
- LCD display measured value directly.
- Built-in microcontroller, with functions of automatic detect to prevent misstatement and set data isn’t lost after power off;
- Flame retardant insulation fiber shell, adopt rapid terminals, output photoelectric isolation, safety and reliability;
- Extensive applications, equipped with temperature and humidity probe of corresponding encapsulation, can measure temperature and humidity of various pipelines and special occasions.
