Siborg's New Tweezer-Meter Packs Benchtop Power in a Pocket

ORLANDO, FL – April 23, 2026 – In a move set to redefine the landscape of portable electronics testing, Siborg Systems Inc. has unveiled its latest innovation, the LCR-Reader-MPB, at the MRO Americas 2026 conference. The new device is a pocket-sized, tweezer-style multimeter that packs a suite of features previously confined to bulky and expensive benchtop equipment. By merging the capabilities of its predecessors and introducing industry-first features, Siborg is aiming to equip field engineers and technicians in critical sectors like aviation, aerospace, and military with unprecedented diagnostic power.

Following a promotional tour that spanned major electronics events in 2025, the company showcased the new flagship device to leading engineers and R&D professionals. The LCR-Reader-MPB represents a significant leap forward in the evolution of handheld test equipment, combining high precision, multifunctionality, and advanced connectivity in a device that weighs a mere 1.3 ounces.

Beyond the Benchtop: A New Standard in Portability and Power

The core promise of the LCR-Reader-MPB is its ability to deliver 'near-benchtop' accuracy in a form factor that fits in a shirt pocket. The device boasts a basic accuracy of 0.1%, a specification that rivals many traditional laboratory instruments. This level of precision is critical for technicians performing maintenance, repair, and overhaul (MRO) on sensitive electronic components where even minor deviations can have significant consequences.

Siborg has engineered the MPB as a comprehensive, all-in-one diagnostic tool. Its versatility is exceptional, integrating a wide range of measurement capabilities. Beyond standard LCR (Inductance, Capacitance, Resistance) and ESR (Equivalent Series Resistance) testing, the device includes an AC/DC voltage and frequency meter, a diode and LED tester, and continuity checking. It also incorporates a signal generator capable of producing sine, triangle, and rectangular waveforms up to 100 kHz, a feature inherited from the award-winning LCR-Reader-MPA model. Furthermore, the inclusion of Analog Signature Analysis, a powerful fault-finding technique brought over from the LCR-Reader-R2 model, allows technicians to create a visual representation of a component's health.

One of the most significant hardware upgrades is the enhanced test frequency, which now reaches 250 kHz. This higher frequency allows for more accurate testing of smaller inductance and capacitance values, a crucial capability when working with modern, high-frequency circuits. To ensure reliability and meet the stringent requirements of its target industries, every LCR-Reader device is shipped with an NIST Traceable Calibration certificate, verified in collaboration with Navair Technologies, a certified calibration facility in Toronto.

The Game Changer: CAN Protocol and Advanced Connectivity

What truly sets the LCR-Reader-MPB apart from the competition is its groundbreaking integration of CAN (Controller Area Network) protocol support. Siborg claims this is the first-ever tweezer-meter to offer this capability. The CAN bus is a robust communication standard ubiquitous in modern automotive, industrial automation, and aerospace systems. By integrating CAN support, the MPB allows technicians to directly interface with and diagnose components within these complex networks without needing a separate, specialized analyzer. This feature alone has the potential to dramatically streamline troubleshooting workflows for vehicle electronics and industrial control systems.

This forward-thinking design is complemented by the latest generation's Bluetooth connectivity. When paired with Siborg's LCR-Reader Data Logger software, the device transforms into a smart, connected tool. Technicians can perform real-time data logging, execute automated Pass/Fail tests, and visually map components for testing. The software supports the import of a Bill of Materials (BOM) and PCB layout images, allowing users to simply click on a component on-screen to guide their testing process. Combined with the device's sub-second evaluation times, this digital workflow drastically increases testing speed and reduces the chance of human error, a critical factor in high-stakes MRO environments.

A Legacy of Innovation for High-Stakes Industries

The LCR-Reader-MPB is not an overnight success but the culmination of over a decade of focused innovation. Siborg's journey in handheld test equipment began in 2014 with the LCR-Reader R1, a simplified and more accessible version of its original Smart Tweezers concept. The company's commitment to pushing the boundaries of portable testing led to a major redesign in 2020 with the LCR-Reader-MPA.

That model's success was validated when it received a Product of the Year award from Plant Engineering Magazine in 2021, recognized for its unrivaled feature set in the Maintenance Tools and Equipment category. The MPA's innovative design, particularly its oscilloscope mode and proprietary calibration boards for measuring sub-pico and sub-nano values, also earned a highlight in NASA Tech Briefs, lending significant credibility to the technology's precision and utility.

The LCR-Reader family has since expanded to include various models tailored to different needs, from the high-frequency R2 to the budget-friendly, multilingual R3. The new MPB synthesizes the best of these developments, creating a flagship product that addresses the most demanding field applications. This consistent track record of developing reliable, high-precision tools has established Siborg as a trusted name for professionals who cannot afford to compromise on accuracy or efficiency. As electronic systems in aviation and military hardware become increasingly complex and miniaturized, the demand for powerful, portable, and intelligent diagnostic tools like the LCR-Reader-MPB is only set to grow.
