Automatic Water Sampler（WS9300/9350）
Short Description:
JIRS WS-9300 & WS-9350 are industrial-grade vehicle-mounted automatic water samplers designed for global environmental monitoring institutes, third-party testing labs, sewage treatment plants, and industrial discharge supervision projects. Equipped with compressor refrigeration + built-in heating modules, the samplers stably preserve water samples at 4±2℃ under extreme ambient temperatures from -30℃ to 40℃, effectively avoiding sample deterioration and ensuring 100% accurate lab test results.
Two configurations optional:
WS-9300: No wheel & handle, compact size 647×400×571mm, net weight 25kg
WS-9350: With moving wheels & hand push handle, easy field transport, dimension 711×460×571mm, net weight 27kg
Core Advantages
Dual Refrigeration & Heating System – Preserve Sample Integrity In All Weather
Compressor mechanical refrigeration with internal circulating fan, precise temperature control at 4±2°C, real-time digital temperature display + high/low temperature alarm
Independent heating modules installed inside refrigeration chamber and pump compartment, anti-freeze design for -30°C frigid outdoor work
Adjustable auto defrost program to cut down manual maintenance work
Professional Programmable Sampling Modes (Global Standard)
Schedule Timed Sampler: Max 24 weekly timing points, customizable single day or full-week execution
Time-Proportional Sampler: Adjustable interval from 1 to 9999 minutes (1min step)
Flow-Proportional Sampler: Link external flowmeter via 4-20mA analog signal
Level-Proportional Sampler: Trigger sampling when water level exceeds preset threshold
Rainfall Trigger Sampler: Match rain gauge for stormwater & CSO monitoring
Instant Manual Spot Sampler: One-click emergency grab sample anytime
Flexible sampling rules: Discrete single-bottle sampling, 1–100 times composite mixed sampling, 1–5 groups parallel replicate sampling. Single volume adjustable 10~1000mL with ±5% precision error; total sampling volume limited under 7000mL to avoid overflow.
Auto Self-Clean Pipeline, Eliminate Cross-Contamination
Auto pipeline rinsing before each sampling, programmable rinse duration
Full pipeline auto drain before & after sampling to stop sediment clogging
Sampling inlet fitted with filter screen/bag to block large impurities, extend pump tube service life
Imported wear-resistant peristaltic pump tubing with built-in service life reminder alert
Complete Data Logging & Power-Off Protection
Sampling records storage: ≥5,000 sets (record time, mode, volume, sampling success status)
Independent alarm log: ≥2,000 records (sampling failure, abnormal temperature, pump error)
Separate logs for instantaneous/cumulative flow, hourly & daily rainfall data (connect external sensors)
Full power-off memory: All parameter settings, system clock and historical records will not lose after sudden power cut
Triple Power Supply For Off-Grid Field Operation
AC Mains: AC110V / AC220V (50/60Hz ±10%) standard plug
Fixed DC: 12V tinned power cord with positive/negative polarity mark
Vehicle Cigarette Lighter: 12V DC plug, ideal for car-mounted mobile supervision
