Product Description:
YJJ 0393 0250 Sulfur Dioxide-Specific Sensor Used For Smoke Gas Analyzers Such As Testo340 350
Features:
0393 0250 is a dedicated sulfur dioxide sensor launched by Testo. It is specifically designed as a backup replacement sensor for models such as Testo 340 and Testo 350, which are smoke gas analyzers. It is commonly used in various smoke gas emission monitoring scenarios. The following is a detailed description of its parameters and uses:
Core Parameters
As this sensor is a dedicated component for smoke gas analyzers, there are relatively few independent parameters available. Considering the product's compatibility scenarios and the characteristics of sensors in the same series, the core parameters are summarized as follows:
Parameter Type Details
Detection Target Sulfur dioxide (SO), a sensor based on electrochemical principle (refer to the general design of Testo's gas sensors in the same series)
Measurement Range The specified range is 0 - 5000 ppm, with a resolution of 1 ppm. It can accurately capture the content of sulfur dioxide at different concentration gradients, suitable for monitoring requirements from low-concentration leaks to industrial smoke gas emissions and other scenarios
Compatible Devices Exclusive to the Testo 340 and Testo 350 portable smoke gas analyzers. As a replacement sensor, it supports quick disassembly, assembly, and replacement to ensure the continuous operation of the analyzer
Auxiliary Features By leveraging the temperature control system and sample pre-treatment functions of the Testo 350 and other analyzers, it can reduce the interference of environmental factors on the measurement; and sensors in the same series are mostly pre-calibrated, so it is speculated that this sensor has been calibrated before leaving the factory and can be quickly put into use after installation. Main purpose
Industrial smoke emission monitoring: This is applicable for the smoke detection of combustion equipment such as boilers and kilns. For industries like chemical, power, and metallurgy, it can monitor the emission concentration of sulfur dioxide in the smoke after combustion in real time using the accompanying smoke gas analyzer. This helps enterprises control combustion efficiency and exhaust gas treatment effects, and avoid penalties for exceeding emission standards.
Environmental inspection and law enforcement: Environmental protection department staff can carry the Testo portable smoke gas analyzer equipped with this sensor to conduct on-site law enforcement inspections. They can quickly detect the emission of sulfur dioxide from scattered pollution sources such as small factories, restaurant kitchens, and heating boilers, and promptly identify violations of emission standards, providing data support for environmental law enforcement.
Equipment operation and calibration: Besides being a core component for daily monitoring, this sensor is also often used as a backup accessory for replacing and maintaining the sensors of related smoke gas analyzers. When the original sensor becomes aged, drifts, or malfunctions, it can be replaced in time to ensure the detection accuracy and normal operation of the analyzer and avoid the disruption of monitoring work due to equipment downtime.
