Water quality monitoring is especially important during the rainy season.
River-basin water quality management, emergency water-pollution testing, and routine soil monitoring create a range of equipment needs for environmental monitoring stations and third-party testing laboratories.
Testing surface water, groundwater, industrial wastewater, and soil samples requires careful consideration of instrument stability, batch capacity, and the requirements of the selected analytical methods.
YETUO environmental laboratory equipment supports workflows including COD analysis, microbial cultivation, sample preparation, and sample drying. Confirm each instrument configuration against the applicable testing method.

The COD testing equipment described below uses air-cooled reflux rather than conventional water cooling for laboratory sample digestion.

HCA COD digestion instruments: available in 6-, 8-, 10-, and 12-tube configurations. Glass reflux tubes support condensation and reflux during sample digestion.

JHR COD constant-temperature heater: provides 12 sample positions for batch processing, temperature control, and an air-condensation structure. It supports sample preparation for wastewater and surface-water COD testing using the reflux method. Confirm the configuration and operating procedure against the method used by your laboratory.


Shaking incubators can support microbial cultivation, strain culture, soil leaching, and shaking extraction during sample preparation. The refrigerated series described in the product materials offers a temperature range of 4–60°C, adjustable orbital shaking, and integrated temperature control. Select vessel capacity, operating conditions, and accessories according to your experimental procedure.


Vacuum centrifugal concentrators combine vacuum and centrifugal action for sample concentration. Different rotor configurations accommodate different vessels and processing needs. They may be considered for concentrating small-volume water samples or organic extracts during analytical sample preparation. Confirm sample compatibility and configuration before use.


Drying ovens are used for drying samples to constant mass, laboratory glassware drying, and soil sample preparation. The equipment described in the product materials uses PID temperature control and hot-air circulation. Drying temperature, holding time, and endpoint should follow the applicable method and sample requirements.

Benchtop and vertical models are available in different chamber capacities for laboratory glassware drying and temperature-controlled preparation of sediment and soil samples.
Depending on the testing scope, laboratories may also require turbidity meters, heavy-metal testing instruments, and other equipment for water and soil testing workflows.
Routine environmental monitoring and emergency pollution screening involve different samples and workflows. YETUO offers laboratory equipment for environmental monitoring stations and third-party testing laboratories. Equipment planning should account for test methods, sample throughput, installation conditions, and maintenance requirements.
