QR-4D tubular intelligent fully automatic carbon sulfur analyzer

Main technical parameters:
Measurement range:
Carbon: 0.010-6.000% Sulfur: 0.003-2.000%
Measurement time: 45 seconds (including sample weighing time)
Measurement accuracy: in accordance with GB223.69-2008 and GB223.68-1997 standards
Description of key characteristics of the instrument:
1. Adopting microcontroller control, fully automatic operation, zero point automatic adjustment completely eliminates human error, reliable performance, strong anti-interference;
2. Equipped with an electronic balance to achieve non quantitative sample weighing, improving detection speed and accuracy;
3. Adopting internationally advanced sensing technology and using imported sensors, the measurement results can be digitally displayed and automatically printed as test results;
4. Both high carbon and low-carbon can be displayed directly without conversion;
5. Use gas capacity to determine carbon and iodine to determine sulfur.
