LPQ-2 Automobile Exhaust Gas Analyzer Detector Emission Analyzer Oxygen AC220v

Description: Lingxin LPQ-2 Automobile Exhaust Gas Analyzer Detector Emission Analyzer Oxygen Content Repair Factory Audit Factory 1. Introduction to the instrumentThe LPQ-2 automobile exhaust gas analyzer analyzes the oxygen content in automobile exhaust gas to determine whether the emission of carbon monoxide (CO) and hydrocarbon (HC) in automobile exhaust meets the requirements of national standards; The oxygen content (﹪) of the exhaust gas reflects whether the air-fuel ratio of the engine is in a dynamic and economical state.This instrument is specially designed for automobile maintenance and repair departments and can meet the needs of exhaust gas. It has the characteristics of compact structure, simple operation, convenient use and low price. It is a testing equipment for automobile maintenance and repair industries.2. Technical parameters1. Measuring range: 0---25﹪2. Measurement accuracy: ±1﹪3. Working environment temperature: 0℃～45℃4. Relative humidity: ≤85﹪5. Response time: ≤15S6. Working voltage: AC220V7. The weight is about 7 kgThree, working principleThe instrument adopts a diaphragm oxygen electrode sensor of plate-Popular method; pure platinum is the cathode, and pure silver is the anode. After oxygen enters the sensor, the oxygen molecules in the oxygen pass through the diaphragm to reach the cathode, and a chemical reaction occurs under the appropriate polarization voltage to make the sensor The electrode current is proportional to the oxygen content in the gas. After the amplifying circuit, the meter directly reads the oxygen percentage.Four, use method1. Debugging:(1) Press the power switch and the power indicator light is on(2) Turn on the air pump to suck in fresh air, preheat it for 15 minutes, and then adjust the "value" knob to make the display show 210, that is, the oxygen content of the atmosphere is 21% (the last digit is a decimal) within the required range for the test, pay attention : The test range referred to here is to adjust the altitude of the test together. For example, if the current instrument is located at an altitude of 1500 meters, the test range needs to be adjusted to 176 and 17.6%. Under normal circumstances, the display can be adjusted to the 210 range.The relationship between atmospheric oxygen content and altitude changes: Pull up height m 0 500 1000 1500 2000 Oxygen content﹪ 20.80 19.60 18.70 17.60 16.55 2. Test:Car 0-bundle pollution testWhen the engine is at working temperature, the engine accelerates from 0 speed to 70% rated speed, and after maintaining for 60 seconds, it drops to 0 speed for measurement on the turntable. See that the debugged instrument is connected to the intake pipe with probe, and the probe probe is inserted into the exhaust pipe of the car with a depth of not less than 200mm. At this time, the instrument switch and the air pump switch should be in the on state, and the display shows a stable value after 15 seconds. After reading the displayed value, this value is the oxygen content in the car exhaust.Under the 0-speed test, when the oxygen content in the exhaust gas is below 14%, the CO and HC emissions meet the national standards. The lower the oxygen content, the better the combustion.When the oxygen content is in the range of 3-6%, the engine is in a state of power and economy, that is, the air-fuel ratio is within the ideal range. Five, matters needing attention1. Frequently check the filter element in the probe handle and the blockage of the filter surface in the filter tube. If it becomes severely black, replace the filter element and filter cotton (absorbent cotton)2. In order to prolong the service life of the instrument, avoid placing the probe in the exhaust pipe for a long time to take gas. 3. All air pipe joints must be tightly sealed to avoid affecting the measurement accuracy. 1. Packing: 1PCS 2.
