Product Description:
YJJ 0554 3385 Backup Particle Filter for Modular Flue Gas Sampling Probe
Features:
0554 3385 is not a gas sensor, but a backup particulate filter of the German brand Testo. It is specifically designed for modular flue gas probes and flue gas analyzers. The core function is to filter particulate impurities in the flue gas and protect the core detection components (such as gas sensors) inside the analyzer. Here are its detailed specifications:
1. Core Specifications
Product Type: Disc-shaped Particulate Filter.
Packaging Specifications: 10 pieces per pack, as disposable spare parts.
Applicable Equipment:
Testo modular flue gas probes;
Testo flue gas analyzers testo 330, testo 340 (the sensor you consulted earlier, 0393 0100, is compatible with testo 340);
Standard probe handle.
Physical Characteristics: White disc structure, compatible with the installation interface at the end of the probe, easy to install (no need for professional tools).
2. Core Functions and Roles
Filter impurities, protect core components:
Particulate matter such as dust, carbon black, fly ash contained in the flue gas, if directly introduced into the internal part of the flue gas analyzer, will block the intake channel of the gas sensor, contaminate the electrodes or sensitive components, resulting in a decrease in sensor sensitivity, an extended response time, and even permanent damage. This filter can effectively intercept these particulate matter, extending the service life of the gas sensor and the analyzer.
Ensure measurement accuracy:
Particulate matter adhering to the surface of the sensor will interfere with gas concentration detection (such as affecting the redox reaction of electrochemical sensors, the light absorption efficiency of infrared sensors), causing measurement data drift and increased errors. By filtering and purifying the intake gas, it can ensure that the sensor and the target gas (such as CO, SO2, NO*, etc.) have sufficient contact, maintaining the accuracy and stability of the detection results.
Suitable for flue gas analysis scenarios:
Mainly used for flue gas emission detection in boiler, combustion equipment, chemical plants, etc. In these scenarios, the flue gas inevitably contains particulate matter produced by combustion, and regular replacement of the filter is necessary to avoid probe blockage and ensure the continuous operation of flue gas analysis work.
3. Usage Precautions
Replacement Cycle: It is recommended to replace the filter regularly based on the concentration of particulate matter in the flue gas (such as every 1-2 times of detection in high dust environments, and multiple detections can be conducted before replacement in regular environments), to avoid filter blockage causing poor flue gas circulation and affecting detection efficiency.
Core Positioning: It is only a consumable accessory, without gas detection function. It needs to be used in conjunction with the core gas sensor of the flue gas analyzer (such as CO, O2, NO* sensors), and cannot be used as a detection element alone.
Product Identification: UPC code is 4029547003165, the country of origin is Qatar, it is an original Testo factory-sourced consumable, ensuring compatibility with the equipment.
