W771-DP10.1 for Food & Pharmaceutical Industry

Infuses German Precision Engineering into Food and Pharmaceutical Safety

Breaking the Dilemma of Traditional Detection, Making Every Drop of Disinfectant Valuable

In critical processes such as food processing, packaging sterilization, and Clean-in-Place (CIP) cleaning, the control of PAA concentration directly affects sterilization effectiveness, equipment lifespan, and regulatory compliance. Industry standards impose strict requirements:

• China GB 14930.2-2022: PAA concentration of food equipment disinfectant must be maintained at 200~2000 ppm

• FDA 21 CFR 178.1010: Residue must be ≤ 1 ppm (final rinse water)

• HACCP Certification: Requires real-time monitoring of Critical Control Points (CCP)

However, the error margin of manual titration reaches ±15%, and test paper methods suffer from delayed response – leading to frequent risks of sterilization failure or equipment corrosion. The W771-DP10.1 Online Analyzer, equipped with the original German DP10.1MA sensor, completely solves these industry pain points!

Why Choose W771-DP10.1?
✅ German "Black Technology" Sensor: DP10.1MA

• Anti-interference Leader: Elastic rubber membrane resists surfactants (zero interference from cleaning agent foam)

• pH-Immune Design: Stable measurement at pH 1~8 (adapts to the acidic phase of CIP)

• Lightning-Fast Response: Captures concentration fluctuations in 90 seconds at 45℃ (4x faster than traditional methods)

• Ultra-Long Lifespan: Corrosion-resistant 1.4571 stainless steel housing + annual maintenance cycle (60% cost reduction)

✅ Superior Control of Intelligent Instrument W771

7-inch LCD Touchscreen

Real-time display of concentration curves, hassle-free GMP audits

Dual Output (4~20mA + RS485)

Direct connection to PLC for PID automatic dosing

Automatic valve shutdown/alarm when concentrations exceed standards

High/Low Limit + Hysteresis Adjustment

Flexible adaptation to filling, soaking, and rinsing processes

Success Case: CIP System Upgrade for a Leading Dairy Enterprise
Pain Points
• PAA concentration fluctuation exceeded ±25% during the acid cleaning phase, causing pipeline corrosion and leakage

• Missed detections in manual sampling led to batch microbial non-compliance, resulting in a loss of RMB 3.8 million

Solution
• Selection & Configuration:

Sensor: DP10.1MA-2000 (measurement range: 5~2000 ppm)

Installation Point: CIP return pipe (1.0bar pressure environment)

Protection Upgrade: Added PETP retainer ring (see Document Scheme 1)

• Intelligent Linkage:

4~20mA signal → PLC dynamically adjusts metering pump

Safety Range Setting: 800±50 ppm (acid cleaning phase)

Over-limit Trigger: >900ppm = stop dosing; <700ppm = sound and light alarm

Results
• 100% Sterilization Compliance: Zero abnormal microbial test results for 12 consecutive months

• 29% Cost Savings: Monthly PAA consumption reduced from 1.2 tons to 0.85 tons

• Passed FDA Unannounced Audit: Full score from the review team for the real-time data recording function
