[The "Determination of Sulfides in Soil and Sediments - Methylene Blue Spectrometric Method (Draft) HJ833-2017 Standard" was implemented on September 1, 2017. The "ZX-DHS Soil Sulfide Acid Blowing Instrument" produced by Beijing Zhongxin Jiayi Technology Co., Ltd. conducted experiments on the water bath temperature range (which affects the recovery rate of detection) and verified that it can achieve a minimum of 92%℃, the effect of temperature on recovery rate can basically meet the requirementsThrough temperature testing, it can be concluded that the ZX-DHS soil sulfide acidification blowing instrument can meet the determination of soil and sediment sulfides using methylene blue spectrophotometry (draft) HJ833-2017 standard
Beijing Zhongxin Jiayi Multi functional Sulfide Acid Blowing Instrument
Sample size: no less than 6 samples
◆ Nitrogen flow control meter: 6 pieces
◆Adopting a closed water bath heating method, the water temperature is set within the range of 0-99 ℃, and the water bath can maintain a constant temperature of no less than 90 ℃ to ensure the achievement of detection conditions
The design concept of one machine for multiple uses meets the requirements for measuring different types of samples such as water, soil, and sediment in experiments
◆ Adopting a single air channel to individually control the flow rate of each position, avoiding mutual interference during the blowing process
◆ Control the rise, stop, and fall of the sample rack through electric means, making the operation more convenient
Multiple electromagnetic stirring systems are beneficial for ensuring the full release of sulfides in soil and sediment
◆ Equipped with a drainage valve for easy discharge of heating water
◆Equipped with water level control and alarm system to prevent instrument damage caused by water shortage
◆Horizontal design, convenient for experimental personnel to install and retrieve samples, easy to operate
Temperature control accuracy: ± 1 ℃
◆Overall dimensions(W×D×H):(1050mm×450mm×700mm)
◆heating power:2000W
◆power supply voltage:AC 220V±10%,50HZ
