FAQS

Frequently Asked Questions FAQ About Soil Tester

What sampling modes does the DR-803C5 water sampler support？

The DR-803C5 offers four professional sampling modes for different scenarios: timed sampling for fixed intervals, time-proportional sampling for consistent time gaps, flow-proportional sampling triggered by water meter data, and external control sampling through dry contact signals. All modes maintain sampling accuracy within 7 error margin.

How does the DR-803C5 ensure sample integrity during outdoor operation？

This industrial sampler features multiple protection systems including automatic tube rinsing before each sample, complete drainage after sampling, and refrigerated storage at 0-5°C. The polypropylene sampling bottle and food-grade tubing prevent chemical absorption while the IP66-rated housing protects against rain and dust.

Can the sampler operate during power outages？

Yes, the DR-803C5 has three backup solutions: its built-in 10.4Ah lithium battery supports 5 days continuous operation, optional solar panel compatibility, and emergency manual sampling mode. The system automatically resumes interrupted sampling cycles when power restores.

What maintenance does the peristaltic pump require？

The precision pump tubes require replacement every 300-500 operating hours. We recommend checking tube elasticity monthly and replacing every 3-5 months depending on water quality. Use only genuine DR-TUBE-803C replacement tubes to maintain the 7 accuracy guarantee.

How does remote monitoring work through the mobile app？

The Android/iOS app connects via 4G to provide real-time GPS tracking, sampling data access, and video monitoring of the intake. Users can adjust sampling parameters remotely and receive instant alerts for leaks or power failures. The system stores 1000+ records locally as backup.
