Dust Monitor DT450G

2016-05-26 15:56:41

Description:

Air pollution control systems such as bag filters and electrostatic precipitators are used to separate particulate or dust from the gas stream before it is exhausted into the atmosphere. To maintain the dust concentration of the emission gas below the specified level through effective operation of the control system, it is essential to continuously monitor the dust concentration of the exhaust gas. Based on installation and application experiences with the old model DT400G, the microprocessor-based DT450G Dust Monitor features improved operationality and reliability. Features include one-touch automatic range setup in response to process conditions and automatic drift compensation. Also, the DT450G can measure at a process temperature of up to 250℃, allowing it to cover a wide range of applications.……
