Applied Humidity Sensor
Applied Humidity Sensor
Product Features
• Highest accuracy
• Excellent protection against pollution
• Outstanding long term stability
• low power consumption
Product Description
ASH-100 is mainly used for monitoring the atmospheric temperature,humidity and pressure. All measured and calculated values are available on the RS-485 interface with Modbus RTU protocol.The compact design with M12 connector allows for easy installation and fast replacement of the probe.
