The Sigma 900MAX automatic water sampler signed by the Institute of Agricultural Environment and Sustainable Development of the Chinese Academy of Agricultural Sciences to our company has been delivered and installed. The 900MAX series water quality sampler has advanced technology and high-quality customer service. It has the accuracy, simplicity, flexibility, reliability and economy that customers care about. The 900 water quality sampler is suitable for regular, equal interval, equal volume sampling, and proportional flow sampling; the 900MAX water quality sampler can meet higher sampling requirements, such as monitoring the overflow of the rainwater-sewage confluence sewer, monitoring the storm drain outlet, and conducting Biological monitoring, or water quality research. American Sigma 900 and 900MAX have three designs: portable water sampler, refrigerated water sampler and all-weather water sampler. The portable water sampler weighs only 28 pounds, and the lifting handle is easy to carry. According to the sampling requirements, it can be configured for single bottle or multi-bottle sampling. Equipped with an interchangeable compact base and standard size base, the compact base is designed to be used for sampling at the 18-inch sewer access port, and can hold 8-1 / 2lbs. Heavy ice and 24 575ml Bottles; the standard base can hold 32lbs. Of heavy ice and 24 350ml bottles. The light beige color of the water sampler helps reflect the sunlight and keep the ice cubes longer. The collected samples are stored in a double-layer insulated base, keeping the temperature low. In addition, it is convenient to set the parameters of the inlet water quality sampler in the field. The refrigerated water quality sampler is fixedly used on site and can work normally in a humid and corrosive environment. The refrigerator is made of stainless steel. The refrigeration temperature is controlled by air induction temperature adjustment, and the high-efficiency compressor, condenser, evaporator and strict foam isolation device ensure the best water temperature of 4 ℃. Forced air purge and front ventilation allow the water sampler to be flexibly placed next to a wall or in the water sampler housing. The keyboard, switch, and display have waterproof and anti-corrosion functions. The sealed connectors and pump shaft ensure that the water sampler is not affected by the environment. The all-weather refrigerated water quality sampler can guarantee the storage temperature of water samples at 4 ℃. The compressor is placed on top of the water sampler to avoid damage caused by hydrogen sulfide and other corrosive gases heavier than air. The high-strength, chemical-resistant outer cover of the water sampler can better protect the refrigeration line from moisture and corrosive gases. The sensor of the water quality sampler system continuously monitors the temperature of the evaporator, the temperature of the ambient air, and the temperature of the sample liquid, and the microprocessor controls the temperature of the water sample chamber. The all-weather refrigerated water quality sampler provides environmentally friendly refrigerants that do not contain Freon.
