H - 3000 hydrogen analysis apparatus Brief introduction:
The instrument can be used for metal, alloy and hydrogen content in the determination of inorganic materials materials. Using pulse melting also - the principle of thermal conductivity detection. Under the carrier gas atmosphere, to a certain quality of samples by pulse furnace heated to a certain temperature, hydrogen release in H2 way, of the sample after purification, the measured gas after thermal conductivity detection unit is converted to electrical signals, by integral method to calculate the hydrogen content. Technical indicators:
1. The detection principle, inert gas protection - pulse heating molten - thermal conductivity method.

3. The scope of analysis: hydrogen: low hydrogen: 0-0.005% *
High hydrogen: - 0.1% *
Note: * 1 g sample, change the sample quantity can expand the measurement range.
4. The analysis accuracy: standard gas: 0.025 parts per million (0 ~ 1 PPM)
Standard sample: 0.2 PPM * * or 2%
Note: * to no greater than the sample standard deviation or uncertainty shall prevail.
5. Spirit acuity: 0.001 PPM
6. Analysis time: general for 3 minutes
7. Sample weighing: general is 1 g, according to the sample content change according to quantity.
8. The carrier: high purity nitrogen;
Dynamic strength: ordinary nitrogen or compressed air.
9. Instrument structure, module structure, by the host, computer, printer, electronic balance, cooling circulating water module composition and so on. Note: * for options.
10. Detection system: hydrogen analyzer thermal conductivity detection system with high precision.
A) detector: the antioxidant NTC thermistor element;
