Function Features

Automatic sampling function	The instrument can realize automatic sampling in time proportion, and the single sampling volume and sampling times can be set;
Automatic emptying function	When the instrument selects the automatic sampling function, the system can automatically drain the water in the tube before and after each sampling to ensure that the sampling pipeline is not blocked by sedimentation;
Automatic rinse function	The sampler can automatically rinse the sampling pipeline before each sampling to ensure that the samples collected each time do not interfere with each other;
Water leak detection	When water leakage occurs in the instrument, the instrument will automatically stop running and alarm;
Battery powered	The sampler is powered by a built-in lithium battery. When fully charged, it can work normally for 5 consecutive days.
Sampling records	Can store 1000 records.
APP control	Sampling control and parameter setting can be performed through the mobile phone APP;
Multiple ways to use	Supports external battery and optional wellhead bracket.

Application Overview

The DR-803C4 automatic water sampler is a hanging automatic water sampler for use in sewage wells. Featuring a built-in lithium battery, it is compact, lightweight, and easy to carry. It features one-touch operation and automatically stops sampling when the set sampling volume is reached. It is ideal for long-term, unattended sampling of sewage wells by third-party testing companies, monitoring agencies, urban construction departments, and water authorities.

FAQS

Frequently Asked Questions FAQ About Soil Tester

How does the DR-803C4 automatic water sampler prevent cross-contamination between samples?

The DR-803C4 features a 3-stage cleaning system: Pre-sampling rinse: Auto-rinses tubing with fresh water (adjustable 1-99 sec)； Post-sampling drain: Fully evacuates residual liquid via patented siphoning tech; UV sterilization (optional): For microbiological sampling applications

What makes the DR-803C4 suitable for deep-well sampling (up to 10m)?

Key engineered solutions: Pressurized intake system: Maintains 0.3MPa suction at max depth; Military-grade cables: Kevlar-reinforced with IP68 waterproof connectors; Tilt compensation: ±15° auto-adjustment to ensure vertical sampling.

Can the sampler operate during power outages?

Yes, with 3 backup modes: 1. 10.4Ah Li-ion battery: 120hr standby / 5-day continuous operation; 2. Solar-ready (24V DC input); 3. Emergency manual sampling via mechanical override.

How does the leakage protection work?

The TripleSafe™ system detects: Water ingress: Optical sensors trigger instant shutdown; Tube cracks: Flow rate monitoring (±7% tolerance); Battery shorts: Galvanic isolation circuitry.

What maintenance does the peristaltic pump require?

300-500 hour service cycle: Monthly: Check tube elasticity (≥85% rebound rate); Quarterly: Replace OEM pump tubes (PN: DR-TUBE-803C); Annual: Lubricate roller assembly (FDA-grade grease included).
