WGJ-III uranium laser measuring device using microcontroller and integrated circuits manufactured abroad famous, seldom fail. In order to allow customers to facilitate the use of this instrument, I take delivery installation and acceptance of delivery methods, and given the warranty of two years. Warranty is limited to repair or replace any defective parts due to the use of defective materials or manufacturing process caused due to improper use or improper storage system caused by human failure and repair costs will charge a fee. Instrument main technical parameters: 1, the excitation source: Imported UV light source 2, the test results: SCM automatically calculated by the large color LCD touch-screen control displays the test results 3 results are saved: through the instrument in front of the embedded built-in thermal The printer prints test results (directly observed convenient), but also by RS232 serial port (or USB interface) to save the data into the general computer 4, the measurement object: direct measurement of liquid samples (solid samples after conversion to the aqueous solution without isolation, enrichment, appropriate diluted to quickly measure) 5, detection limit: ≤0.02ng / ml (three times the standard deviation of the definition) 6, the measured uranium Range: 0 ~ 20ng / ml, the higher the concentration of the sample to be an appropriate dilution 7, measurement accuracy : ≤4% 8, the linear correlation coefficient: r≥0.999 9, accuracy: ≤8% 10, linear storage: 11 standard curves can be stored off the operability: The software automates frequency regulation, humane step instructions guide the operating procedures 12. Stability: Preheat measured after 1h, 2ng / ml standard test 8h uranium relative standard deviation ≤ ± 7% 13, the working environment: temperature at 10 ℃ ~ 40 ℃, humidity less than 85% (30 ℃) 14, volume: 491 × 364 × 208 mm 15, Weight: 10Kg 16, power supply:.
