For decades, Valhalla Scientific’s Model 4176 µ-Ohmmeter has been a trusted solution for engineers and technicians requiring high-accuracy, low-resistance measurement. Known for its reliability and precision, the 4176 has long been a standard in applications ranging from component testing and production lines to R&D labs and aerospace environments.
Now, Valhalla Scientific is proud to introduce the new generation Model 4176 — a complete upgrade that maintains the accuracy engineers rely on, while adding modern connectivity, usability, and safety features designed for today’s demanding workflows.
Building on Proven Accuracy
At its core, the new 4176 maintains what has always made it indispensable:
- 0.04% basic accuracy
- 1 µΩ to 30 kΩ measurement span
- Seven ranges (manual or Auto-Range)
- Four-wire Kelvin connections for uncompromised precision
These foundational features remain unchanged, ensuring full continuity with the trusted performance of the legacy 4176.
Smarter Connectivity
One of the most significant upgrades is in interfaces and communications. The new 4176 addresses and eliminates the connectivity limitations of its predecessor:
- RS-232 and USB are now standard, making integration plug-and-play
- Optional Ethernet enables remote access and network integration
- Improved serial stability and an expanded command set ensure seamless automation and data exchange
This means fewer headaches with connectivity — and more time focused on measurement.
Flexible Testing with the New Hi-Lo Comparator
The Hi-Lo Comparator (HLC) mode has been expanded. While both versions support traditional Min/Max limit testing, the new 4176 introduces a Nominal ±% deviation mode, making batch testing and quality control even more versatile.
With clear LED indicators, audible alerts, and optional relay outputs for automation, the HLC function reduces human error and speeds up pass/fail testing in both lab and production environments.
Advanced Display & Usability
The outdated VFD display is gone. In its place is a bright, high-contrast OLED display with an auto-dim screensaver to extend display life. Even more importantly, the new Stored Power-Up Settings feature allows users to define their preferred startup configuration — including range, TCM, HLC, and Peak Mode — with a single press of the Store button. No more reconfiguring the instrument every time you power up.
Safety & Measurement Enhancements
Valhalla has also strengthened the 4176’s safety and functionality:
- Improved Peak Mode now displays Peak Hi, Peak Lo, and the current reading simultaneously
- Range 0 Safe Mode ensures no current is sourced when selected
- Optional Interlock Current Disable (ICD) adds a hardware-level safeguard, disabling output unless terminals are shorted together
These updates give operators greater confidence and protection when testing sensitive devices or operating in production environments.
Precision Under Any Conditions: Temperature Compensation
Many materials, like copper or aluminum, change resistance with temperature. That’s why the 4176 continues to include Valhalla’s Temperature Compensation Mode (TCM), powered by the Omni-TC sensor.
With TCM, users can compensate for any coefficient and reference temperature (e.g., 20 °C) and see both the compensated resistance value and the real-time ambient temperature directly on screen. For detailed analysis, the uncompensated value is also available via the instrument’s serial interfaces.
Accessories & Integration
To round out its flexibility, the new 4176 supports optional accessories:
- Omni-TC Temperature Sensor – required for TCM operation
- RX-3 Rack Mount Adapter – for integration into 19-inch test racks
The Next Generation of the 4176
The Model 4176 has always been about one thing: delivering accurate, repeatable, and reliable low-resistance measurements. With this new generation, Valhalla Scientific has brought the 4176 into the modern era — combining trusted performance with smarter connectivity, greater usability, and enhanced safety.
Whether you’re working in aerospace, defense, automotive, or R&D, the new 4176 µ-Ohmmeter is ready to take its place as the next-generation standard for precision ohmic measurement.
