G921 typePortable residual chlorine analyzer
Product Introduction
Portable residual chlorine analyzerUsing colorimetric measurement, advanced solid-state cold light source, narrowband interference technology, and microcomputer automatic data processing, the concentration value of the sample is directly displayed.
Pure Chinese display allows for a more intuitive display of detection data, guided detection mode reduces learning costs, and users can easily and quickly determine pollutants.
application area
The industries of hospital wastewater, dialysis water, swimming pool water, aquaculture, waterworks, and purified water plants.
Performance characteristics
The equipment is developed based on the national standard DPD spectrophotometric method.
Portable design, no need for external power supply, can quickly measure sewage quality in laboratories and fields.
Based on solid-state light source and narrowband filter for optical processing, ensuring accurate measurement within the range.
The instrument is composed of a solid-state light source and a narrowband filter to ensure high performance and stable results.
The automatic backlight and power-saving mode have increased the standby time of the device.
Guided operation during the measurement process allows for faster hands-on operation of the equipment.
