Triton™ Triple-Axis Micrometers

Product Inspection Moves To A New Dimension

LaserLinc introduced the first Triton™ triple-axis micrometers in 2006—when the Triton312™ and Triton330™ , brought an entirely new dimension to your product measurement and inspection.

The Triton series of micrometers (Triton312™, Triton330™, Triton331™, and Triton360™) are THE most precise solution for inspecting the outer diameter and ovality of products such as catheters, insulated wire, and glass rods—as well as measuring the outer diameter and ovality of all types of machined parts, including centerless ground parts. Compared to two axis micrometers, the Triton series of micrometers provides a more precise average OD and better flaw detection capabilities.

Triple-Axis Ovality Measurement

Measuring the ovality—also called eccentricity—of nearly round and elliptically shaped products with a dual-axis micrometer is prone to error (see graph on opposite page). By combining three simultaneous diameter measurements spaced equally over 120 degrees, Triton micrometers provide near-perfect measurements of ovality on elliptically-shaped products, regardless of the angle at which they are oriented.


How much more accurate is a triple-axis micrometer? The degree of improvement over a two-axis micrometer depends on how out of round the product is. The standard deviation of the diameter measurements from a triple-axis micrometer can be as much as 100 times better than the reported average diameters from a two-axis micrometer.

As for hard-to-find flaws that don’t encircle the product, a LaserLinc triple-axis micrometer is more than twice as likely to detect such flaws as a two-axis micrometer. Click here to see an illustration of some of the flaws that a Triton can detect.

Lobing Detection

Attention centerless grinders! Lobex™ Lobing Detection System is a real-time tool for detection and elimination of lobing problems. That’s right, with Lobex you can detect lobing as it occurs. Combine a high-speed Triton with LaserLinc’s special lobing software package.

But which Triton?

It’s all about you and your application. With measurement rates from 900 to 12,000 per second, and fields of view from .0035" and up, there’s a Triton micrometer for just about any application. Call LaserLinc and speak with our application experts to decide which Triton micrometer will be most advantageous for you specific needs.

Triton micrometers are ideal for:

More precise OD measurement.

Accurate ovality & eccentricity measurement.

Flaw detection.

Measurement of transparent material.

Quantifying lobing in centerless ground parts.

Optional features include roller-guides and a stand to assure easy startup and accurate and continual measurement at high line-speeds; an air purge to maintain operation in harsh environments; and a calibration kit to ensure optimum accuracy.

For optimal inspection of your products, add the Profile Vu oscillating micrometer fixture.

The Triton micrometers are an essential addition to any process that relies on accurate diameter and ovality measurements. Still not sure? Try one out! With LaserLinc’s unconditional 30-day return policy, you have nothing to lose. Call or e-mail us today.

Control Systems Interface

If your process is regulated by a PLC or other process control system, LaserLinc’s SmartLinc™ processor offers a simple and affordable data-only interface to integrate LaserLinc’s laser micrometers into your system. The processor communicates via EtherNet/IP or as ASCII data over an Ethernet or serial connection to the PLC. A single unit provides a communications link for one, two, or three of LaserLinc’s micrometers.

A note about model numbers. The name of a LaserLinc micrometer indicates the number of scanning axes and the maximum measurement size, therefore a Triton312 has three scanning axes and a 12mm gate size.

LaserLinc’s laser and ultrasonic measurement systems are certified to North American safety standards including UL, ANSI, CSA, ASTM, and NFPA.
