Introduction:
HE400 series and HE200 series are temperature, relative humidity transmitters, adopt import
components and high-performance low-power SCM design, which assure the quality and stability. HE400
series and HE200 series support two kinds of output, Voltage and Current. They have unique design
features to ensure no circuit interface of themselves. They are wall-mounted and enjoy widely measuring
range and high accuracy, suitable for DC16V-30V. HE400 series has LCD display, HE200 series has no
LCD display. Besides, both of them have internal and external probe. Customers can have many choices
according to their demands.
Applications
：
HE400 series and HE200 series are designed for temperature and humidity control in conditioning and
ventilation application in the following sectors: pharmacy, museums, clean rooms, ventilation ducts,
industrial and civil sectors, crowded places, canteens, auditoria, gyms, high-density farms, greenhouse, etc.
