Technical Resource Center

Guides, parameters and insights for monitoring projects

Huisheng resources bring together the technical context behind product selection: system architecture, monitoring parameters, sampling and pretreatment guides, FAQ, inquiry preparation and the News & Insights article library.

Technical Guides

Reference pages for project preparation

Each guide answers a different technical question before product selection. This keeps resources useful for engineers, contractors and international customers without turning the resource center into a blog feed.

Environmental laboratory and monitoring parameter reference for water gas VOC and sampling projects
Parameter Reference

Separate the parameter group before selecting instruments

Water analyzers, stack gas systems, VOC detectors and samplers are not selected by product name only. Huisheng clarifies the parameter group, sample condition and reporting purpose first.

Water parametersCOD, BOD, NH3-N, TP, TN, heavy metals, cyanide, fluoride ion (F-), volatile phenol, pH, turbidity, conductivity, DO and temperature.
Gas parametersSO2, NOx, CO, CO2, O2, HCl, HF, dust, PM, humidity, flow, pressure and temperature.
VOC and toxic gasVOCs, NMHC, benzene series, H2S, NH3, CO, O2 and combustible gases.
Sampling conditionsSampling flow, sampling volume, heated line, filtration, condensation control, sample preservation and container method.
News & Insights

Application articles and selection notes

Part of the resource center: practical articles on wastewater monitoring, CEMS selection, VOC and toxic gas detection, sampling stability and inquiry preparation.

Quick FAQ

Common technical questions before selecting equipment

Start with sample medium, monitoring point, target parameters, expected measuring range and installation environment. Then decide whether a single analyzer, multi-parameter system or outdoor station is suitable.

Common water parameters include COD, NH3-N, TP, TN, heavy metals, pH, DO, turbidity and conductivity. Gas parameters include SO2, NOx, CO, CO2, O2, HCl, HF, dust, flow and temperature. VOC and toxic gas parameters include VOCs, NMHC, benzene series, H2S, NH3, CO, O2 and combustible gases.

A continuous emission monitoring system is a stack monitoring system that usually includes sampling, pretreatment, gas analysis, dust or particulate measurement, stack condition instruments, data acquisition and reporting interface.

Huisheng reviews application industry, sample medium, parameters, measuring range, installation site, continuous or portable requirement, data output, power supply, communication method, standards, quantity and destination country before quotation discussion.

Yes, range discussion depends on selected model, method and project requirement. Huisheng reviews the expected concentration range before quotation.
