Feature: 1. [Auto Compensation] This industrial dust detector adopts original sensor, with automatic temperature compensation, zero drift and full range drift compensation. 2. [High Safety] The dust detector has automatic protection against high concentration gas impact and sensor fault self check function, highly reliable. 3. [Circuit Protection] The dust concentration alarm adopts circuit protection design, greatly reducing the failure rate during installation and use. 4. [Infrared Remote Control] Using infrared remote control method, the detector can be adjusted without opening the cover, safe and convenient. 5. [High Measurement Accuracy] Full range temperature digital automatic tracking and compensation, ensuring measurement accuracy. 6. [Alarm Method] Support on site sound and light alarm, external alarm, remote controller alarm, data collection alarm, etc. Standard configuration for two level alarms, optional for three level alarms. 7. [Die Cast Aluminum Shell] The shell is made of die cast aluminum, sandblasted with oxidation fluoronitrogen paint, explosion proof and anti corrosive.
