Using "single-line spectrum" technology, measurement is not interferenced by background gas; gas detection technology based on the combination of off-axis multiple reflection and inverse differential filtering algorithm, with better detection limit level; based on wide dynamic search Peak and online deviation correction technology, good measurement stability and accuracy.
Using "single-line spectrum" technology, with high measurement accuracy, and it is not interferenced by the background gas. The long optical path absorption cell is designed based on the White-type structure combined with the plane reflection. The laser is incident on the White-type absorption cell in an off-axis manner. Through the off-axis multi-reflection optical path multiplexing, the measurement optical path is increased, and the inverse differential filtering algorithm is combined to improve the detection limit level. Based on the online automatic correction technology, when the absorption signal of the gas to be tested drifts out of the allowable position, the absorption peak of the gas to be tested is automatically corrected to the center point, and the absorption signal of the gas to be tested is automatically locked in real time to prevent the absorption signal of the gas to be tested from drifting out of the peak-seeking range. The measurement data is recorded in real time, and the data can be printed through a bluetooth printer or exported from a USB device with one press, which is convenient for data traceability. The built-in electronic flow sensor makes it easy to check the flow on the interface. High temperature heat tracing design, the heat tracing temperature can reach 220 ℃, avoiding the problems of condensation, adsorption and crystallization. The product is highly integrated, small size, light weight, and easy to carry.
