Product features:
The measurement principle adopts the ultraviolet absorption spectrophotometer method. The light source adopts a pulsed deuterium lamp with long lifespan and fiber optic transmission, and a 2048 bit pixel CCD holographic grating spectrometer is used to form the optical measurement system of the instrument.
2. It can simultaneously monitor the concentrations of H2S, SO2, COS, and CS2 in the process gas flow. And provide real-time air demand command signals to the upper computer through 4-20mA analog output.
3. High testing accuracy and rapid response. Accuracy: ± 1% FS (H2S, SO2); Repeatability: ± 1% FS (H2S, SO2);
Sensitivity: 1% FS (H2S, SO2); Linearity: ± 1% FS (H2S, SO2);
Response time: T90<10 seconds
4. The sampling probe using patented technology does not require the use of heated sampling pipelines. The probe is directly installed on the process pipeline, combining traditional steam tracing methods with air cooling and using a dedicated temperature sensor to condense sulfur into liquid form inside the probe and drip it back into the main pipeline. This avoids complex processing related to sulfur and eliminates its impact, completely solving the problem of blockage in the sampling pipeline. It truly achieves online continuous monitoring, avoids downtime, and reduces daily maintenance work.
5. Fiber optic transmission, ultraviolet light is transmitted through fiber optic to a specially designed sample chamber, eliminating the need for heating pipeline gas transmission and adopting microprocessor control, greatly reducing the time required for maintenance work and routine maintenance.
6. The instrument has automatic diagnostic function, automatic calibration, fault alarm function, indicator light prompt, and operation is very simple.
7. CSA explosion-proof certification, applicable to Class 1, Div 2, Groups C, D, T3 occasions.
8. Equipped with an intrinsically safe handheld operation keyboard, easy to use, allowing users to safely configure and monitor analytical instruments even in hazardous environments.
