The implementation of the HJ833-2017 standard for the determination of sulfides in soil and sediment using methylene blue spectrophotometry (draft) began on September 1, 2017,The "ZX-DHS Soil Sulfide Acid Blowing Instrument" produced by Beijing Zhongxin Jiayi Technology Co., Ltd. is an instrument that can basically meet the requirements of this method and is suitable for soil new standard detection, such as the required water bath temperature range for experimental requirements (which can affect the recovery rate of detection), and the operation of soil samples after being placed in reaction bottles.
I hope this instrument can truly bring convenience to laboratory personnel.
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
