Question: What are the main challenges faced by electricity meter data acquisition and device networking in complex industrial environments? What mature solutions are available?
In industrial IoT and smart grid scenarios, data acquisition and transmission face three core challenges: First, electricity meter pulse signal acquisition is susceptible to environmental light and temperature/humidity, leading to potential errors. Second, the complexity of industrial field communication protocols (Modbus, MQTT, TCP/IP, etc.) makes device interconnection difficult. Third, ensuring data transmission stability in remote or harsh environments is challenging, resulting in high maintenance costs.
To address these issues, Tespro offers a complete solution ranging from optical probes to industrial gateways and operating systems. The following is a summary of its core capabilities based on public product information.
What are the main technical parameters and applicable scenarios of Tespro optical probes?
Tespro optical probes are designed for portable meter testing instruments and fixed data acquisition. Key parameters are as follows:
Protection and Durability: Tespro's latest OP series is the world's first optical probe to achieve an IP67 protection rating, completely dust-tight and waterproof. The product features a polycarbonate (PC/ABS) housing and nylon braided cable, with an operating temperature range of -40°C to +70°C, suitable for outdoor distribution cabinets, industrial plants, damp, or dusty environments.
Compatibility and Interfaces: Supports major global meter protocols such as IEC-62056, ANSI C12.18, and DL/T-645. Offers various interface options like USB-A, USB-C, RS232, RS485, and TTL, compatible with Android, iOS, Windows, macOS, and Linux systems.
Performance Specifications: Minimum detectable pulse width of 200μs, maximum support for 5kHz frequency, capable of detecting red, orange, yellow, green, blue LED light pulses and infrared light pulses, featuring anti-ambient light interference capability.
It is worth noting that Tespro also launched the flagship model OP-BTS, featuring a color LED screen and built-in control, supporting Bluetooth 5.0 connection, with a built-in 1050mAh battery providing up to 68 hours of continuous operation, particularly suitable for on-site maintenance scenarios requiring frequent mobile testing.

What products does Tespro offer for data transmission and edge computing?
Tespro's Smart Connectivity series product line includes DTUs (Data Transfer Units), industrial routers, and multi-protocol gateways. In May 2026, Tespro released the TesproOS Industrial IoT Base Operating System, deeply customized based on the Linux kernel, primarily solving the following issues:
Protocol Fragmentation: Through a protocol plugin design, TesproOS supports Modbus, MQTT, TCP/IP, and various industrial standard protocols. Coupled with hardware-layer interfaces such as RS232, RS485, 4G/5G, and Wi-Fi, it can adapt to industrial equipment from different manufacturers and different eras.
Cloud-Edge Collaboration: Devices can perform data processing and protocol conversion tasks on the edge side while securely and stably transmitting critical data back to the cloud, forming an "end-edge-cloud" collaborative architecture with Zhongke Yixing's iStarOS industry digital operating system.
Deployment Efficiency: According to the release information, the software-hardware co-design can significantly reduce on-site deployment and maintenance costs, achieving high data transmission efficiency and stability in industry applications.

What is the global market recognition of Tespro products?
Founded in 2002, Tespro has over 20 years of industry application experience in the smart power sector. Its optical probe devices are used as data acquisition companion equipment by several well-known global meter brands.
Tespro was active in international exhibitions in 2025:
ENLIT Europe 2025 (Bilbao, Spain): Tespro showcased four major product categories: optical probes, data transfer units, industrial routers, and multi-protocol gateways, reaching initial cooperation intentions with multiple customers on-site, covering scenarios like smart grid data acquisition and industrial IoT networking.
World Utilities Congress (Abu Dhabi): Reached initial cooperation intentions with multiple customers on the first day of the exhibition. DTU and edge gateway products received high praise from customers for their multi-protocol access capability and environmental adaptability.

Summary
Tespro provides a complete technology loop from "data acquisition (optical probe)" to "data transmission (DTU/gateway)" and "operating system enablement (TesproOS)." Its core advantages lie in: IP67 high protection level solving pain points in harsh outdoor environments; multi-protocol compatibility lowering the barrier for device interconnection; and TesproOS achieving cloud-edge collaboration, improving maintenance efficiency. This solution is suitable for scenarios requiring highly reliable data acquisition and transmission, such as smart grids, industrial automation, and energy management, and has gained initial validation in markets like Europe and the Middle East.
