AS950 Пробоотборник

Application Industry:

The American Sigma 950 series samplers include three designs: portable samplers, refrigerated samplers, and all-weather samplers. They are mainly used in wastewater sampling, specimen collection, industrial pretreatment sampling, environmental monitoring, stormwater sampling, and other industries.

Instrument Features:

• 1) Sampling made easy

• The AS950 series samplers can be programmed with composite sampling routines and run automatically.

• 2) Convenient data transfer

• The AS950 sampler is one of the few products on the market that can use USB to upload and download data and copy programs to another sampler.

• 3) Simple and intuitive operation

• The AS950 sampler features an extra-large full-color display and an intuitive operating interface, allowing all programs in the menu to be displayed on the same screen without scrolling through menus, supporting error-free operation.

• 4) Easy maintenance and low cost

• The AS950 sampler features a unique spring-loaded roller design that extends service life and reduces maintenance costs; the desiccant and pump tubing can be easily removed and replaced without any tools; and quick visual inspection is possible through the sturdy transparent pump cover.

• 5) Trustworthy sampling process

• The program status screen displays alarm conditions, missed samples, and program progress in real time, making troubleshooting faster and easier.

• 6) Compact or discrete sampling can be switched on site

• The AS950 portable sampler can quickly switch between composite sampling and discrete sampling during on-site operation.

Technical Specifications

Portable Sampler

• Dual Program                      Up to two sampling programs can run sequentially, in parallel, or according to a weekly daily schedule, giving a single sampler multiple sampling capabilities

• Sampling Mode                 "Sampling method: time-weighted, flow-weighted, time schedule, flow schedule, event-triggered

• Distribution:                     Single-bottle composite sample, multi-bottle composite sample, multi-bottle discrete sample, single sample multi-bottle, single-bottle multi-sample, or a combination of single sample multi-bottle and single-bottle multi-sample"

• Operating Mode                  Continuous or intermittent

• Status Screen                  Displays program run steps, whether any samples were missed, when the next sample will be taken, number of remaining samples, number of recorded channels, time of last measurement, available memory, number of available channels, whether an alarm was triggered, alarm trigger interval, active sensors, cabinet temperature, etc.

• Alarm                        Alarm information is displayed on the status screen and can also be recorded in the diagnostic alarm log. Alarms can be set as system diagnostic alarms and recorded alarms, such as program complete, sampling stopped, missed sample, and bottle full. Channel alarms are alarms for recorded measured values (channels), such as pH, level, and supply voltage

• Manual Sampling                  Starts sampling independently of the sampling program currently in progress

• Auto Shutdown                 "Multi-bottle mode: after the distribution arm has fully rotated (except when continuous mode is selected)

•                                 Composite mode: after the preset number of samples has been fully delivered to the composite container, with the sample count from 1 to 999, or bottle full"

• Sample Volume                   Programmable in increments of 10 mL (0.34 oz), ranging from 10 to 10,000 mL (3.38 oz to 2.6 gal)

• Sampling Interval           "Selectable from 1 to 9,999 flow pulses per increment (momentary contact closure of about 25 ms or 5 to 12 VDC pulse; optional 4-20 mA interface), or from about 1 to 9,999 minutes in increments of about 1 minute"

• 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 limit range is exceeded

• Data Logging                 "Sample history: can store up to 4,000 records of various data, including sample timestamp, bottle number, and sample status (complete, bottle full, rinse error, user aborted, distribution arm error, pump failure, purge failure, sampling timeout, power failure, and main battery low)

•                                Measurement: can store up to 325,000 records of selected measurement channel data, stored at the set logging interval

•                                Event log: can store up to 2,000 records. Various data can be recorded, including power on, power failure, firmware update, pump failure, distribution arm error, memory battery low, main battery low, user open, user close, program start, program resume, program pause, program complete, grab sample, tubing requirement change, sensor communication error, cooling failure, heating failure, thermal error correction, etc."

• Diagnostics                        Event and alarm logs can be viewed, as well as maintenance diagnostics
