When to Invest in a Faro Laser Tracker vs. Sticking with a Fluke Multimeter: A Procurement Manager's Perspective

It's Not About the Price Tag, It's About the Application

I'm the procurement guy who's built spreadsheets for everything. I've managed our metrology equipment budget for seven years, and I've seen more purchase requests than I'd like to admit. One question I get asked over and over is, "Should we just buy a Faro Vantage laser tracker, or is a Fluke multimeter good enough?" The honest answer? It depends on what you're measuring, how often you're measuring it, and what happens if you get it wrong.

This isn't a "one-size-fits-all" answer. I've seen a $500 Fluke do a perfect job on a $10,000 project, and I've watched a $30,000 Faro tracker become a shelf ornament because the team overestimated its daily need. So, let's break this down into three common scenarios I've run into.

Scenario A: The New Production Line (High Precision, High Frequency)

If you're starting up a new production line for automotive chassis components or aerospace assemblies, where tolerances are in the tenths of a millimeter and you're checking every part, the Faro Vantage is the obvious choice. That's the easy one.

I audited our 2023 spending on a new line. The engineering team wanted a Faro Vantage. My first reaction was sticker shock: a full system with the tracker and software can run $30,000 on the low end, $60,000 for a fully featured setup. The Fluke 87V, their alternative, was $500. But here's what the spreadsheet showed.

We estimated 2,000 measurement points per part, 100 parts per week. With a Fluke and a few calipers, that would take 30 minutes per part. With the Faro laser tracker, it took 4 minutes. Assuming a fully loaded operator cost of $50/hour, the Fluke method was $25/part, or $2,500/week. The Faro method was $3.30/part, or $330/week. Over two years, that's a labor savings of over $220,000. Plus, the Faro’s *Inspect* software flagged a geometry issue in week one that would have caused a $15,000 rework. That's a return on investment you'll never get from a Fluke.

The decision was clear. If you're measuring high volumes of critical parts, the Faro Vantage pays for itself in months.

Scenario B: The Retrofit of an Old Line (Low Volume, High Precision)

Here's where it gets tricky. I've got another line that's been running for 20 years. We're retrofitting a robot arm, and we need to check the alignment of a few critical pins. The tolerance is tight, but we only need to do this maybe three times a year. I was pushing for a portable CMM arm rental because the Faro Vantage felt like overkill.

The risk was tempting fate. The upside of buying a full Faro system was having it on hand whenever needed. The downside? A $40,000 asset that sits idle for 350 days a year. Honestly, I'm not sure why some engineering teams consistently overbuy for one-off projects. My best guess is it's fear of being wrong on the day of the measurement.

We did a TCO analysis for three years. A rental of a Faro Arm for a week at a time was about $2,500 per incident. That's $7,500/year. A Fluke 187 and a set of precision calipers cost $800 total and could handle the check if we put a jig in place. The risk was a $1,200 redo if the jig was off. After comparing the options, we went with the Fluke and a custom fixture built for $500. It worked. For low-frequency, high-precision tasks, a Fluke multimeter and a good jig often beat the cost of a dedicated laser tracker.

Scenario C: The General Inspection (Medium Volume, Standard Precision)

This is the middle ground, and I've seen it go wrong both ways. You're not doing aerospace tolerances, but you're also not just checking continuity. Think welding fixtures, or checking the squareness of a large frame. Here, the temptation is to default to a Fluke multimeter or a Leica Disto, but the time cost can be hidden.

I've seen a team spend two hours with a Fluke and a square to check a weldment that a Faro Arm would have checked in 15 minutes. They weren't wrong—they were slow. The hidden cost wasn't the $50/hour labor. It was that the weldment sat in inspection for a day, delaying the production schedule by eight hours. That delay cost $1,200 in idle assembly time.

In Q2 2024, when we switched vendors for a new frame supplier, I had to decide: buy a cheap laser distance measurer or upgrade to a mid-tier CMM. We ended up with a Faro Arm rental for the first month and then bought a used Faro Fusion arm for $15,000. We cut inspection time from 4 hours to 40 minutes per part. The Fluke multimeter was a great diagnostic tool, but for measuring a 6-foot frame, the laser arm was simply more efficient.

How to Decide Which Scenario You're In

Here's a quick way to figure it out. Sit down with your production schedule and the last ten inspection reports. Ask three questions:

1. Volume: How many parts do you inspect per week? If it's less than 10, and the tolerance is standard, a Fluke multimeter with a fixture is probably fine.
2. Consequence of Error: What happens if you miss a measurement by 0.5mm? If it's a $50 rework, don't buy a Faro. If it's a $10,000 scrap part, buy the tracker.
3. Frequency of Need: Are you doing this once a month, or every day? If it's monthly, rent the equipment. If it's daily, buy it.

Take it from someone who's paid for both. The Faro Vantage laser tracker is a phenomenal tool. So is a Fluke 87V. The difference is in the TCO of your specific application, not the price tag on the invoice.
