The Constant Temperature and Constant Flow Atmospheric/Particulate Matter Sampler is a multifunctional integrated sampling device developed by our company for the collection and monitoring of various toxic and harmful gases, total suspended particulate matter (TSP), inhalable particles (PM10, PM2.5), airborne heavy metals, fluorides, and semi-volatile organic compounds (SVOCs) in ambient air. This instrument features low power consumption, low noise, lightweight design, and high load capacity.

The Flue Gas and Particulate Matter Concentration Tester is a portable detection device that integrates particulate matter sampling, particulate concentration measurement, flue gas pollutant sampling, and flue gas pollutant concentration measurement. The tester has upgraded its measurement and control system, resulting in improved stability and precision.

The portable analyzer employs a hydrogen flame ionization detector (FID) detection technology that complies with EN 13526, EN 12619, EPA Method 25A.

The instrument uses a main unit with full-temperature heated FID technology and features a built-in high-temperature catalytic device. The main unit measures the total hydrocarbon value, while the high-temperature catalytic device measures the methane value. The difference between the two values provides the non-methane total hydrocarbon value.

The ZHK3601 is a new generation thermal desorption system that integrates an automatic sample injection system and a thermal desorption device. It serves as a sample pretreatment system compatible with various brands of gas chromatography (GC) for the analysis of volatile organic compounds (VOCs). The APK720R is equipped with an automatic sampler capable of handling up to 72 adsorbent tube samples, significantly enhancing the instrument's analytical capacity and processing efficiency. The fully upgraded control system makes operation simpler and more intuitive. It can also be used in conjunction with the gas bag automatic sampler (APK2600) for the pretreatment of gas bag samples (Tedlar bags).

The ZHK2720 Electromagnetic Radiation Analyzer is an instrument used for monitoring electromagnetic fields across power frequency, low frequency, high frequency, ultra-high frequency, microwave, and radio frequency ranges. It can accurately and quickly measure various complex electromagnetic environments. By changing the probe, it can measure the electric field strength, magnetic field strength, magnetic induction strength, and power density across different frequency ranges.

The ZHK6250 Fully Automatic BOD Analyzer is an automated detection instrument suitable for measuring biochemical oxygen demand in surface water, domestic sewage, and industrial wastewater.

The gas detector features an integrated design, precise structure, and stable performance. It is primarily used for the rapid detection of toxic and harmful gases in the ambient air on-site. It can measure 24 gas components simultaneously without the need for on-site sensor replacement.

This instrument measures the oil content in water using infrared spectrophotometry.It is ahigh-tech productthat integrates optics, analytics, electronics, and mechanics. By scanning the absorbance values at "3030-1, 2960-1, and 2930-1" of the sample, the analyzer determines the total concentration of oil in the water, achieving true three-wavelength measurement. Users do not need to createst and ardcurves,perform zero adjustments,estab-lish a platform, or carry out calibration during usage, which ensures simple operation and high accuracy.

The ZHK2503N  gas flowmeter consists of a flowmeter module with an orifice, a soap film flowmeter module, a mass flowmeter module, a microcontroller, a display screen, and other components.

The Portable Online Noise Monitoring Instrument is a compact environmental noise monitoring device that features total value analysis, integrated measure-ment (including customizable integration time), statistical analysis (including hourly and daily statistical analysis), octave band and 1/3 octave band filters, among other functions. The system is capable of continuous operation under all weather conditions and is characterized by its small size, comprehensive functionality, and ease of operation and maintenance. It can reliably work in various complex environments, with an external operating temperature range of (-30 to 70) °C.
Applications: Mobile monitoring, third-party monitoring, noise optimization site selection, regional site adjustment, temporary emergency monitoring, etc.
