Water Quality Automatic Sampler

Water quality automatic samplers collect water samples from rivers, canals, wastewater streams, and treatment plant process points at programmed intervals or flow-proportional trigger events without requiring manual collection by field personnel at each sampling time. Environmental monitoring agencies, municipal water treatment authorities, industrial effluent compliance teams, and irrigation water quality programs across Pakistan use automatic samplers to build representative water quality datasets across extended monitoring periods at unmanned or remote sampling locations.

The sampler uses a peristaltic pump to draw water through a collection tube from the intake point to individual sample bottles inside the sampler housing. Intake tubes use weighted strainers at the submerged end. These prevent debris ingestion while maintaining consistent sample collection depth at the monitoring point. Pump tubing uses silicone or Marprene material compatible with the target water chemistry. Tube replacement maintains contamination-free sample collection between monitoring campaigns. Additionally, sample distribution systems use a rotating distributor arm. This directs each collected sample into a separate numbered bottle, keeping individual time-stamped or event-triggered samples isolated from each other within the sampler bottle tray.

Bottle configurations run from 24 individual 1-liter bottles up to single composite collection containers of 10 to 20 liters. Time-proportional programming collects samples at fixed intervals between 15 minutes and 24 hours. Flow-proportional programming links the sampler to a flow meter signal. Samples trigger at defined flow volume increments rather than fixed time intervals. Furthermore, refrigerated sampler variants use an integrated cooling unit maintaining sample temperature at 4°C between collection and retrieval. This preserves biological and chemical sample integrity across extended deployment periods before laboratory analysis.

Programmable controllers set sampling schedule, bottle sequence, flush volume before each collection, and pump speed through a front panel display. Data logging records collection time, bottle number, and flow meter readings for each sample event. Moreover, weatherproof housing rated IP55 or higher protects electronics and mechanical components during outdoor installation at riverbanks, canal monitoring stations, and wastewater treatment plant effluent points across Pakistan’s varied climate conditions.

Tactical Supply Pakistan supplies water quality automatic samplers to environmental monitoring agencies, municipal water treatment authorities, industrial effluent compliance teams, and irrigation water quality programs requiring unmanned representative water sample collection capability across environmental and process monitoring applications throughout Pakistan.
