Product Introduction

TP-USB Series Optical Probe is a product created by Tespro in 2005. Its current technologies and the application property that is applicable to almost all types of electric meters and thermo meters make it exceptionally unique among the optical probe families of Tespro China, which has always been following the philosophy of quality first and the original USB chip available in the UK that can be used to achieve plug and play to all operating systems without requiring any drivers, thus it is more convenient to use.

Meanwhile, we are demanding to use wide temperature cable materials to make sure that the product would operate normally within the temperature range of - 40 deg C to + 70 deg C. As it has always been the case, we follow quality in the course of 20 years. TP-USB was initially developed and built by Tespro Electronics Co., Ltd. (Tespro China).

Reliable Optical Communication for Smart Metering

The state of the art AMI systems need consistent and reliable data capture at the meter level. Reading by hand was time-consuming and prone to error.
The optical probes produced by Tespro, such as the TP-BT and USB lines, allowed automatic data access through optical ports, and were compatible with different brands of meters and protocols. Bluetooth and USB models were flexible both in the field and desktop.

Product Case

Sept. 8, 2022 - one of the largest U.S. customers has ordered 275 TP-USB optical probes directly through our company, which will be used to activate smart meter data collection, Industrial IoT monitoring, and tests of the equipment on-site throughout the country.

 

USB functionality is the highlight feature of the probe, which allows on-board data storage- which means that the laptops do not have to be carried to the field location and thus data can easily be transferred to the computers after the collection process.

 

The TP-USB probes literally change the way the field work is done because the probes are provided with inbuilt USB data storage ensuring that the technicians are able to gather meter reading without laptops in the field and later relay the data collected to the computers once they are out of the field.

 

Customer feedback attests to the groundbreaking efficiency improvements: such USB-powered plug-and-play design saves onsite operation time by 35 percent, eliminates data errors by 40 percent, and saves maintenance expenses by 28 percent.

 

The solution has been known to be reliable in its operations and has optimized the workflow, and that is why it is a favorite solution to all future deployments of the client.
