Professional Alignment with the LM320 Digital Angle Finder
Equip your toolkit with our professional-grade Digital Angle Finder. We designed the UNI-T LM320 series to precisely measure slopes, bevels, and inclines in real-time. It protects you from costly alignment errors in carpentry, metal fabrication, and construction scenarios. Whether you are installing countertops or routing pipes, this device delivers reliable, instant results. Explore our full range of Layout and Measurement Tools to ensure comprehensive precision for your daily operations.
Furthermore, professional machinists must adhere to rigorous engineering specifications. Experts explicitly rely on the NIST dimensional metrology standards to establish strict angular precision baselines. Thus, we engineered this inclinometer with an advanced high-resolution sensor natively. Ultimately, it guarantees your projects meet demanding industrial quality requirements flawlessly.

1Secure Magnetic Attachment
We engineered the LM320 series for diverse and demanding applications. Holding a gauge manually while adjusting heavy machinery is dangerous. Fortunately, this electronic goniometer features a powerful magnetic base (the LM320C model uniquely features magnets on 3 sides). It attaches directly to miter saw blades, steel pipes, and metallic conduits securely, keeping your hands completely free during complex alignments.
24×90° Range & Auto-Rotating LCD
Our high-quality sensing module delivers fast, sensitive, and accurate readings across a full 4×90° range. You can rely on the high-definition backlit LCD. It features a smart gravity sensor that automatically flips the displayed numbers upright whenever the device is inverted, ensuring you can read critical data clearly from any awkward viewing angle.
3Relative & Absolute Measurement Modes
Calculating angle differences mathematically wastes valuable production time. The device supports instantaneous zeroing at any arbitrary position securely. Consequently, users can switch between absolute gravity-based true horizontal angles and relative comparison slopes effortlessly with just a single click, eliminating human error.
Core Capabilities of the Magnetic Inclinometer

Strong Magnetic Base
Attaches firmly to ferromagnetic surfaces like saw blades and pipes for stable, hands-free measurements.

4×90° Measurement
Covers a full 360 degrees. The smart display auto-rotates for effortless reading when upside down.

Data Hold Function
Press the HOLD button to lock the current display data instantly, making recording extremely easy.

Smart Auto OFF
The instrument automatically shuts down after 3 minutes of inactivity to maximize your battery lifespan.
Investing in a reliable Magnetic Inclinometer is essential for maintaining occupational accuracy and project compliance. The LM320 series combines pocket-sized portability with industrial-grade precision, making it the perfect diagnostic tool for both professional mechanics and dedicated DIY woodworking enthusiasts evaluating their setups.

FAQs
Q1: What is the main difference between the LM320C and the LM320D/E/F models?
A1: The LM320C features a PC plastic body with magnets on 3 sides. The LM320D/E/F models are upgraded with a durable aluminum alloy frame, bottom magnets, and support additional engineering measurement units (mm/m and in/ft).
Q2: Can I set the angle to zero at any position?
A2: Yes. This digital angle finder features both absolute and relative modes. You can place it on any uneven surface, press the REF/ABS button to set it to zero, and accurately measure the relative angle from that specific point.
Q3: Will the numbers be upside down if I attach it under a pipe?
A3: No. The high-definition backlit LCD is equipped with a smart gravity sensor. Whenever the inclinometer is inverted, the numbers on the screen automatically flip upright, making it incredibly easy to read from any angle.
Q4: Is the magnetic base strong enough to hold itself securely?
A4: Absolutely. The built-in heavy-duty magnets are designed specifically for industrial applications. They will hold the goniometer securely to miter saw blades, welding tables, steel pipes, and metallic ventilation ducts without slipping.
