Product description
Technical indicators
Hach American Sigma 950 series samplers have advanced technology and excellent customer service. They have the precision, simplicity, flexibility, reliability and economy that customers care about. The AS950 series samplers are suitable for regular, equal interval, equal volume sampling, and flow ratio sampling; they can meet higher sampling requirements, such as monitoring the overflow of rainwater-sewage confluence sewers, monitoring storm drains, conducting biological monitoring, or Conduct water quality research, etc. American Sigma 950 series includes three designs: portable sampler, refrigerated sampler and all-weather sampler. It is mainly used in wastewater sampling, specimen collection, industrial pretreatment sampling, environmental monitoring, rainwater sampling and other industries.
 
Portable sampler
 
  The portable sampler weighs only 28 lbs. 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 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, the sampler parameters can be conveniently set on site.
 
Application range
 
● Environmental monitoring
● Rainwater sampling
 
Refrigerated sampler
The refrigerated sampler is fixed 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 a water sample temperature of 4 ℃. Forced air purge and front ventilation allow the sampler to be placed flexibly beside the wall or in the sampler housing. The keyboard, switch, and display have waterproof and anti-corrosion functions. The sealed connectors and pump shaft ensure that the sampler is not affected by the environment.
 
Application range
 
● Wastewater sampling
● Specimen collection
● Industrial pretreatment sampling
● Environmental monitoring
● Rainwater sampling
 
All-weather sampler
The all-weather refrigerated sampler can guarantee the storage temperature of the water sample at 4 ℃. The compressor is placed on top of the sampler to avoid damage caused by hydrogen sulfide and other corrosive gases heavier than air. The sampler is equipped with a high-strength, chemical-resistant outer cover, which can better protect the refrigeration line from moisture and corrosive gases. The sensor of the system continuously monitors the temperature of the evaporator, the temperature of the ambient air, and the temperature of the sample liquid, and the temperature of the water sample chamber is controlled by the microprocessor. The all-weather refrigerated water quality sampler provides environmentally friendly refrigerants that do not contain Freon.
 
Application range
 
● Wastewater sampling
● Specimen collection
● Industrial pretreatment sampling
● Environmental monitoring
● Rainwater sampling

Sampling characteristics
Dual program
Up to two sampling programs can be run sequentially, in parallel, or according to the weekly worksheet. Make a single sampler with multiple sampling functions
 
Sampling mode
Sampling methods: time weighting, flow weighting, time schedule, flow table, event trigger
Distribution: Single bottle mixed sample. Multiple bottle mixed sample. Multiple bottle discrete sample. Single sample multiple bottle. Single bottle multiple or single sample multiple bottle and single bottle multiple combination continuous or intermittent
Operating mode
 
Continuous or intermittent
Status screen Shows the program running steps, whether there are missing samples, when the next sample is taken, the number of remaining samples, the number of recorded channels, the last measurement time, the available memory, the number of available channels, whether it is an alarm trigger, alarm trigger interval, active Sensor and cabinet temperature, etc.
Call the police
The alarm information is displayed on the status screen. It can also be recorded in the diagnostic alarm log. Alarm can set system diagnostic alarm and record report
Warning, such as the completion of the procedure, termination of sampling, missing sampling and full bottles, etc. Channel alarm is an alarm for the recorded measurement value (channel), such as PH value, liquid level and power supply voltage, etc.
Manual sampling Start sampling independent of the ongoing sampling procedure
Automatic shut-down
Multi-bottle mode: After the dispensing arm is fully rotated (except continuous mode)
Mixing mode: After the preset number of samples has been transferred to the mixing container, the number of samples is 1 to 999. or full bottle
Sample volume Measure TOC, TIC, TC and VOC
Sampling time interval

Choose from 1 to 9,999 flow pulses in single increments (momentary contact closure for 25 ms or 5 to 12 volts DC pulse; optional 4 to 20 mA interface), or 1 to 999 minutes in 1 minute increments

Setpoint sampling trigger
If a flow sensor or PH / temperature sensor or other external detection device is installed, sampling will be triggered after the set limits are exceeded
 
data record
The sample history can store up to 4000 various data, including sample timestamp, bottle number and sample status (completed. Bottle full, flush error, user abort, dispensing arm error, pump failure, purge failure, sampling timeout, power failure) And the main battery is low)
Measurement: It can store up to 325,000 data of the selected measurement channel. These data can be stored in the event log according to the set recording interval. Up to 2000 records can be stored. Can record various data,
Including power-on, power failure, firmware update, distribution arm error, low memory battery power, low main battery power, user on. User off, program start, program resume, program pause, program completed, grab samples, changes in tube requirements , Sensor communication error, cooling failure, heating failure, thermal error correction, etc.
diagnosis Can view event and alarm logs, and maintenance diagnosis
