Product details
The system collects sample gas through a probe, and after heating and dry chemical treatment, the sample gas is converted into gas, which is then continuously measured by a photodetector. The mercury concentration is calculated and displayed. When measuring total mercury in garbage, heating and dry chemical treatment are used to remove Hg from the sample gas2+Reduce to Hg for measurement; When measuring elemental mercury, the sample gas is not subjected to any treatment; The difference between total mercury and elemental mercury is the ionic mercury content.
• Automatic calibration
Total mercury, elemental mercury, and ionic mercury can all be measured
• Low cost of ownership
• Simple operation and safe design
• Simple and compact structure, easy to maintain
High detection sensitivity, accurate detection results, fast detection speed, and easy operation
High reliability, very suitable for on-site use
No additional reagents are required, avoiding reagent contamination during the measurement process
Measurement objectOptional ionic mercury, elemental mercury, and total mercury content
