Description: JCJ175 temperature and humidity transmitter is a feature-rich, stable performance, economical and practical temperature and humidity measurement products. JCJ175 humidity and temperature transmitter series is divided into six categories from the shape structure: JCJ175A wall-mounted temperature and humidity transmitter JCJ175C Duct temperature and humidity transmitter screwed JCJ175D Duct straight bar JCJ175E air temperature and humidity transmitter Tube flanges fixed temperature and humidity transmitter JCJ175F remote temperature and humidity transmitter JCJ175P remote temperature and humidity transmitter JCJ175 series of temperature and humidity transmitter imported digital temperature and humidity sensor, which has a stable performance and good consistency digital signal output strong anti-interference ability and other characteristics. Temperature and humidity transmitter with analog voltage or current output or digital communications output or relay outputs independently controlled and built-in buzzer alarm, LCD backlit LCD display and many other features, this product can be achieved by temperature and humidity measurement and control, communications. Main features: ◆ Excellent performance, high accuracy, for a variety of environmental temperature and humidity measurements ◆ standardized design, beautiful appearance, scientific structure, wall installation, easy disassembly ◆ sensors placed on the outside of the transmitter, will help improve the measurement accuracy and ease of use ◆ provide two standard analog signal output ◆ Equipped with LCD display and a standard RS-232 or 485 communication interface, can be directly connected with a computer (for the user save the digital instrumentation and data acquisition) ◆ can Optional temperature and humidity alarm output (1-4 optional) Typical applications: industrial site monitoring and control, HVAC land, buildings, rooms, archives, greenhouses, supermarkets, workshops, warehouses, construction sites, temperature and humidity monitoring and control a variety of temperature and humidity measurement system, monitoring and control applications. Nine pure health science and technology for the development of temperature and humidity transmitter JCJ175 appropriate monitoring and control systems and related software.
