Sulfide Blowdown Meter

Product Description：

1、Principle

Sulfide in water samples by acidification, hydrogen sulfide generated with the carrier gas (nitrogen) into the absorption bottle / absorption of the color tube by the absorption solution (zinc acetate - sodium acetate solution or 2% sodium hydroxide solution), select the appropriate analytical method on the absorption of sulfur ions absorbed in the absorption bottle / absorption of the color tube for analysis and determination.

2、Product use

Water sulfide acidification blowing instrument according to the determination of water sulfide - methylene blue spectrophotometry (iodometric method) standard development and production. Meet the water quality sulfide determination of sample pretreatment needs.

3、Product implementation standards

2022 new national standard HJ1226-2021 “Determination of water quality sulfide - methylene blue spectrophotometry

Product features：

1、Large capacity reaction bottle, can handle multiple samples at the same time.

2、Hydrochloric acid port, gas inlet and outlet are integrated and independent of each other, the operation will not interfere.

3, constant temperature water bath heating, with rapid automatic thermostat control system, the heating temperature can be set manually.

4、The lifting and rotating sample holder which is adjusted by the fixed knob of lifting and lowering position and gas distribution system, installing the sample at the front side, easy to operate.

5、The nitrogen flow rate of each sample is independently controlled and regulated or closed, and the needle valve gas flow meter accurately controls and displays the total gas consumption.
