Máy kiểm tra chất lượng không khí NCS-NMHC-1000

NCS-NMHC-1000

Description

Responding to the inspection requirements for environmental air quality and pollution source emission in the domestic. environmental protection industry, our company independently developed NCS-NMHC-1000 type non-methane hydrocarbon analyzer according to HJ/T38-1999 Standard , based on the non-methane total hydrocarbon analyzer used in laboratory, and combined with domestic and foreign advanced experiences in the same industry. To meet the specific requirements of users, this product has achieved the strongest practicability and the highest cost performance, under the premise of possessing various performance indicators.

Features

Hydrogen flame ionization detector with high sensitivity.

Unique chromatographic column switching and combination technology, advanced modular amplifier system with highly-integrated instrument circuit, modular design and extremely high operational stability.

Real-time display of various data spectrum based on the realization of full IoC (Inversion of Control) function.

Full automatic ten-way valve online real-time sampling, dedicated chromatographic column, short analysis cycle, appearance of peak within 25 seconds and assurance of no sample residue, and wide analysis range(linear range: 10⁷).
