Developed by our companyDPI-01The portable laser micro water analyzer is a portable instrument based on laser spectral absorption technology for detecting micro water content in gases,Utilize water in gasdivideCharacteristics of Infrared Spectral AbsorptionDesign, capable of completing-60℃～-20Measurement of water vapor within the temperature range of ℃, ensuring full range coverage±The measurement accuracy of 2 PPM, combined with the temperature measured by the temperature sensor, compensates for the impact of temperature on measurement through special circuit design and algorithm processing, which can effectively eliminate detection errors caused by aging and drift, without the need for frequent calibration.

1. Fiber optic sensors directly detect SF₆Water molecule content in gas, absolute error≤±2 PPM； Using on-site SF₆Within the dew point range, we have better dew point accuracy,-The accuracy is ± 1 ℃ at 60 ℃, ± 0.5 ℃ at -50 ℃, ± 0.3 ℃ at -45 ℃, and ± 0.1 ℃ at -40 ℃.

2. Infrared spectroscopy absorption method is used for detection, with strong anti-interference ability. "A micro water detection system based on scanning method" has already obtained a utility model invention patent (patent number: ZL 2011 2 007 4340.0）。

3. Fully self-developed, with independent property rights and related patents.

4. Compact structure, small volume, easy to carry.

5. Seven inch high-definition LCD touch screen, touch operation, simple and intuitive.

6. Adopting high-capacity lithium batteries, suitable for on-site operations.

7. Imported components are selected for the internal air circuit of the instrument, with good sealing performance and no issues during the testing processSF₆Gas leakage.
