Customer Cases

Customer Profile

• Industry: Pharmaceutical Distribution
• Country: United States
• Company Type: Mid-sized Pharmaceutical Warehouse (storing temperature-sensitive vaccines and medications)
• Core Need: 24/7 stable monitoring of indoor temperature/humidity to meet FDA storage regulations (2–8°C, 30–60%RH) and avoid product spoilage.

Challenge

• Legacy sensors lacked waterproofing; frequent condensation (from warehouse cooling systems) caused 2 sensor failures in 3 months, leading to 12 hours of unmonitored conditions.
• Poor readability: Old analog displays were unreadable in low-light warehouse aisles, forcing staff to carry flashlights for on-site checks.
• Electromagnetic interference (from warehouse forklifts/equipment) caused data drift (±1.2°C), resulting in 3 false regulatory compliance alerts.
• Limited probe flexibility: Fixed probes couldn’t adapt to cold-storage zones (requiring -20°C monitoring), requiring separate (costly) specialized sensors.

Solution

• Waterproof & durable design: IP68 PG7 cable gland + multi-layer waterproof gaskets + conformal-coated circuit board, eliminating condensation-related failures in high-humidity cooling zones.
• High-visibility display: Bright LCD screen for clear reading in low-light aisles, removing the need for flashlight checks.
• Anti-interference capability: Built-in anti-interference module, ensuring stable data (±0.5°C accuracy) even near forklifts/equipment.
• Flexible probe customization: Swapped the default probe for a high-temperature (-40°C~120°C) variant, enabling monitoring of both standard (2–8°C) and cold-storage (-20°C) zones with a single sensor.
• Wide-voltage power supply (10–30VDC): Seamless integration with the warehouse’s existing DC power system.

Results

• Regulatory compliance secured: 0 sensor failures or data drift in 12 months; stable temperature/humidity data (±0.3°C/±2%RH) ensured 100% pass rate for FDA audits.
• Cost savings: Eliminated need for separate cold-storage sensors (saving $1,200 annually); reduced maintenance labor by 80% (no more flashlight checks or frequent replacements).
• Operational efficiency: Real-time 1s data refresh + clear displays cut on-site monitoring time by 15 hours per week.
• Probe flexibility: Swappable probes allowed the temperature and humidity meter to adapt to 3 distinct warehouse zones (standard storage, cold storage, packaging areas), reducing equipment inventory by 60%.
