Sulfide acidification blowing device

Product Overview:

HCA-310Sulfide acidification blowing deviceisMeet the pre-treatment standards for sulfide samples in water qualitySulfide acidification blowing device.

　　The sulfides in the water sample are acidified, and the generated hydrogen sulfide enters the absorption bottle/tube with the carrier gas (nitrogen) and is absorbed by the absorption solution (zinc acetate sodium acetate solution or 2% * solution). The corresponding analysis method (GB/T16489-1996 "Determination of Sulfides in Water Quality - Methylene Blue spectrophotometric method", HJ/T600-200 "Determination of Sulfides in Water Quality - Iodometric method") is selected to analyze and determine the sulfur ions absorbed in the absorption bottle/tube. Suitable for the determination of sulfides in surface water, groundwater, domestic sewage, and industrial wastewater.

　　Using a constant temperature water bath for heating, PID precise temperature control, and a fast automatic constant temperature control system to shorten analysis time. The hydrochloric acid inlet, gas inlet, and outlet are integrated and independent of each other, and their operations do not interfere with each other. Automatic liquid level detection and replenishment of water bath system. Large capacity reaction bottle, independent six unit module, capable of processing six samples simultaneously. The nitrogen flow rate and blowing time of each sample are independently controlled. The large LCD touch screen display control is clear at a glance.

Performance characteristics:

Large capacity reaction bottle, independent six unit module, capable of processing six samples simultaneously.

Constant temperature water bath heating, PID precise temperature control, fast automatic constant temperature control system.

The hydrochloric acid inlet, gas inlet, and outlet are integrated and independent of each other, and their operations do not interfere with each other.

Automatic liquid level detection and replenishment of water bath system.

Independent control of nitrogen flow rate and blowing time, automatically shutting off the gas source when the set time is reached, saving nitrogen without the need for personnel to shut it off.

Adopting a 7-inch color touch screen microcomputer human-machine interaction system, various instrument parameters can be independently set.
