🔧 Industrial Maintenance Engineer Reviews

⭐⭐⭐⭐⭐ James Wilkins - Industrial Maintenance Engineer
"The 3D3Y Digital Panel Multifunction Meter has significantly improved our facility’s energy monitoring. We’ve had the Pro model installed since February 2025, and over six months of continuous operation in a high-temperature plant environment, it's performed flawlessly. The Premium RS485 communication integrates perfectly with our SCADA system, and the largest LCD display makes readings easy even from a distance. Customizable units were a big plus for aligning with our reporting standards."

🏠 Residential Energy Monitor Enthusiast Reviews

⭐⭐⭐⭐☆ Priya Mehta - Home Energy Management Enthusiast
"I installed the Base model in my home distribution box back in November 2024 to track household energy consumption. After 8 months of use, I’m quite satisfied. The LCD display with green backlight is clear and easy to read, and the RS485 interface allowed me to connect it to my home automation system with some technical help. Setup was a bit tricky for a non-electrician, but once configured, it’s been rock solid. Great for DIY smart home integrators who don’t mind a learning curve."

🏭 Factory Automation Manager Reviews

⭐⭐⭐⭐⭐ Carlos Mendez - Factory Automation Manager
"We integrated ten Advanced Model units across our production lines in April 2025, and the impact on our energy efficiency tracking has been impressive. The enhanced RS485 communication ensures zero data loss, and the +15% extended measurement range handles our variable loads without issue. The meters are compact enough to fit in tight distribution panels, and their -25℃ to 70℃ operating range holds up even near heat-generating machinery. A reliable, professional-grade solution."

🏢 Commercial Building Facilities Manager Reviews

⭐⭐⭐⭐☆ Linda Park - Facilities Manager, GreenTower Office Complex
"Purchased the Base and Pro models for different zones in our office building in January 2025. After 6 months, the performance is consistent. The customizable measurement units helped us standardize reporting across tenants, and the durable build withstands the electrical fluctuations common in older infrastructure. Only downside: initial configuration requires a qualified technician. But once set up, it’s maintenance-free. Solid choice for commercial energy audits."

🛠️ Electrical Contractor Reviews

⭐⭐⭐⭐⭐ Derek Foster - Licensed Electrician
"I’ve installed over 30 of these meters in various industrial and residential projects since June 2024. The three-phase compatibility and compact 96x96mm design make them ideal for standard DIN rail mounting in distribution boxes. Clients love the real-time energy tracking, and the RS485 integration is a game-changer for building management systems. The intuitive interface reduces commissioning time. Highly recommend the Pro model for industrial clients who need precision."
