In the rapidly developing landscape of Industrial IoT and smart grids, the accuracy of data acquisition and the stability of data transmission have become core challenges in the digital transformation of enterprises. Faced with complex industrial field environments, how can we ensure the precise acquisition and stable return of electricity meter data?
As a brand with over 20 years of experience in the smart power and energy equipment field, Tespro has launched a full range of industrial IoT products, from optical probes to industrial routers, providing end-to-end reliable solutions for global users.

Optical Probe: Precise Acquisition, Unfazed by Harsh Environments
The acquisition of electricity meter pulse signals is the "first mile" of power metering. Tespro optical probes are designed specifically to solve this pain point, with core advantages reflected in three dimensions:
1. World-Leading Protection Level
Tespro's newly launched OP series optical probe is the world's first optical probe product to achieve an IP67 protection rating. This means the product is completely dust-tight and can function normally even when submerged in water. Coupled with the nylon braided cable providing superior tensile and abrasion resistance, it remains stable and reliable even in harsh environments such as outdoor distribution cabinets, damp basements, or dusty factories. Additionally, the product's operating temperature range covers -40°C to +70°C, adapting to all types of extreme climates, from severe cold to intense heat.
2. Wide Compatibility and High Sensitivity
Tespro optical probes are compatible with major global electricity meter communication protocols such as IEC-62056, ANSI, and DL/T-645, and support various interfaces like USB-A, USB-C, and RS232, enabling seamless connection with smart meters of different standards from different countries. In terms of performance, the probe can sense various colors of LED light pulses (red, orange, yellow, green, blue) and infrared light pulses, with a minimum detectable pulse width of 200μs and a maximum sensing frequency of 5kHz. It also possesses anti-ambient light interference capability, ensuring accurate acquisition both indoors and outdoors.
3. Flexible Product Model Options
Tespro offers a rich product line to meet different scenario needs. Notably, the flagship model OP-BTS is equipped with a color LED screen and built-in control system, supports Bluetooth 5.0 wireless connection, and has a built-in 1050mAh battery providing up to 68 hours of continuous operation, making it particularly suitable for portable meter testing and on-site maintenance operations.

Edge Gateway and Industrial Router: Making Data "Connectable and Transmittable Stably"
If the optical probe is the "eye" for data acquisition, then Tespro's DTUs, industrial routers, and edge gateways are the "nervous system" for data transmission and processing.
In May 2026, Tespro officially launched the TesproOS Industrial IoT Base Operating System, marking a key upgrade for Tespro's smart connectivity products from "hardware-driven" to "software-hardware synergy."
TesproOS, deeply customized based on the Linux kernel, targets industrial routers and edge gateways, providing powerful support for device access, data transmission, edge computing, and remote operation and maintenance. Its core capabilities include:
Multi-Protocol Integration: Fully supports Modbus, MQTT, TCP/IP, and various industrial standard protocols, compatible with wired and wireless interfaces like RS232, RS485, 4G/5G, and Wi-Fi, breaking the deadlock of protocol fragmentation in traditional industrial environments.
Cloud-Edge Collaboration: Leveraging TesproOS and the iStarOS industry digital operating system, Tespro's smart connectivity products enable seamless linkage between real-time data processing on the device side and intelligent decision-making in the cloud, significantly reducing on-site deployment and operational costs.

Global Validation, Proven Reputation
Tespro's product strength has gained extensive validation in the global market. At top international industry exhibitions in 2025, such as ENLIT Europe and the World Utilities Congress in Abu Dhabi, Tespro products continuously attracted the attention of many overseas customers. Its core products, including optical probes, industrial routers, and multi-protocol gateways, became focal points, garnering broad technical recognition and initial cooperation intentions from regions like Europe, the Middle East, and Southeast Asia.
From precise acquisition optical probes to stable transmission industrial gateways and cloud-enabled operating systems, Tespro is providing a complete "end-to-cloud" technology loop for the global energy digital transformation. If you are facing challenges in industrial IoT data acquisition and connectivity, Tespro is worth your in-depth understanding.
