The Hash American Sigma 950 series sampler features advanced technology and high-quality customer service, delivering the precision, simplicity, flexibility, reliability, and cost-effectiveness that customers value. The AS950 series sampler is suitable for timed equidistant volumetric sampling and flow ratio column sampling; It can meet higher sampling requirements, such as monitoring the overflow of the sewer where rainwater and sewage converge, monitoring the rainstorm outfall, conducting biological monitoring, or conducting water quality research. The American Sigma 950 series includes three designs: portable sampler, refrigerated sampler, and all-weather sampler, mainly used in industries such as wastewater sampling, specimen collection, industrial pretreatment sampling, environmental monitoring, and rainwater sampling.

Portable sampler

Portable sampler, weighing only 28 pounds, comes with a lifting handle that is easy to move. According to the sampling requirements, it can be configured for single bottle or multiple bottle sampling. Equipped with an interchangeable compact base and standard size base, the compact base is designed for sampling in 18 inch sewer manholes and can hold 8-1/2lbs Heavy ice and 24 575mL bottles; The standard base can hold 32lbs The heavy ice and 24 350mL bottles, coupled with the light beige color of the sampler, help reflect sunlight and extend the shelf life of the ice cubes. The collected samples are stored in a double-layer insulated base and kept at a low temperature. In addition, it is convenient to set the parameters of the sampler on site.

Application scope

Environmental monitoring
● Rainwater sampling

Refrigerated sampler
The refrigerated sampler is fixed for use on site and can work normally in humid and corrosive environments. The refrigeration machine is made of stainless steel material. Refrigeration temperature is controlled by air induction temperature regulation. High efficiency compressor, condenser, evaporator and tight foam isolation device ensure 4 ℃ water sample temperature. Forced air blowing and front ventilation allow the sampler to be flexibly placed next to the wall or inside the sampler casing. The keyboard, switch, and display screen all have waterproof and corrosion-resistant functions, and the sealed connectors and pump shaft ensure that the sampler is not affected by the environment it is in.

Application scope

● Wastewater sampling
● Specimen collection
● Industrial pre-processing sampling
Environmental monitoring
● Rainwater sampling

All-weather sampler
The all-weather refrigerated sampler can ensure that the storage temperature of water samples is at 4 ℃. The compressor is placed at the top of the sampler to prevent damage from hydrogen sulfide and other corrosive gases heavier than air. The sampler is equipped with a high-strength, chemically resistant outer cover, which can better protect the refrigeration pipeline from moisture and corrosive gases. The system's sensors continuously monitor the temperature of the evaporator, ambient air, and sample liquid, and the microprocessor controls the temperature rise of the water sample chamber. The all-weather refrigerated water quality sampler provides refrigerants that are environmentally friendly and free of Freon.
