 Product introduction:
1. Product principle

The sulfide in the water sample is acidified ａnd the hydrogen sulfide generated is absorbed with the carrier gas (nitrogen) into the absorber/absorber chromogenic tube (zinc acetate sodium acetate solution or 2% sodium hydroxide solution). The sulfur ions absorbed in the absorber/absorber chromogenic tube are analyzed ａnd determined by the corresponding analysis method.

2. Product use

Qylhw-4 water sulfide acidification gas meter is developed ａnd produced according to the standard of determination of water sulfide - methylene blue spectrophotometry (iodine content method). It fully meets the requirements of sample pretreatment for determination of water quality sulfide.

3. Product implementation standards

GB/ t16489-1996 determination of water quality sulfide - methylene blue spectrophotometry

HJ/ t600-2000 determination of water quality sulfide －－ iodine content method

Product features:

1. Large-capacity reaction bottle can process multiple samples simultaneously.

2. The three ports of hydrochloric acid, gas import ａnd export are integrated ａnd independent, ａnd the operation will be free from interference.

3. Constant temperature water bath heating with rapid automatic constant temperature control system. The heating temperature can be set manually.

4. The lifting ａnd rotating sample frame ａnd the air distribution system are adjusted by the lifting ａnd rotating knob at the lifting position.

5. The nitrogen flow of each sample can be adjusted or closed independently, ａnd the needle valve gas flow meter can accurately control ａnd display the total gas consumption.
