Buying FLIR Cameras, Multimeters, and Calipers: A Procurement Manager's FAQ

What you'll find here

I'm a procurement manager at a 38-person industrial services company. I've handled our testing and inspection tool budget for six years, watched every order go through our cost tracking system, and wasted enough money on the wrong tool to learn when to spend more. This FAQ covers the gear questions I get asked most often.

• FLIR E86 thermal camera vs. FLIR TG298 thermal imaging camera
• Multimeter vs. thermal camera — do you need both?
• Where to buy Mitutoyo calipers without getting counterfeit
• Encoder distributors vs. direct manufacturer orders
• When rush delivery isn't a waste
• The hidden costs nobody quotes

Let's get to it.

Should we buy the FLIR E86 thermal camera or the FLIR TG298 thermal imaging camera?

Depends on who's holding it. The FLIR E86 thermal camera is the workhorse we recommend for anyone who thinks a thermal image is a data record, not just a pretty picture. It's got enough resolution to spot a failing bearing or a loose connection before it becomes an emergency. The FLIR TG298 thermal imaging camera is what I call a 'point-and-shoot with a brain.' It's an infrared thermometer with an imaging sensor, made for quick checks of electrical panels and HVAC equipment. It doesn't give you the full analysis toolbox of the E86, but you don't need that if you just want to know whether a breaker is running hot.

By the way, pull the FLIR datasheet before you compare model names. The accuracy spec and measurement range are what matter when someone's maintenance decision depends on a temperature delta.

From a cost perspective, the E86 is a much bigger upfront number. I wouldn't buy one for a team that only needs a yes/no scan. And I wouldn't buy a TG298 for a condition monitoring program where we're tracking trends over time. The money is better spent on the tool that matches the task.

Do I still need a multimeter if I have a thermal camera?

Yes. A thermal camera tells you something is hot. A multimeter tells you whether that something has a voltage problem, a current problem, or a wiring problem. They're not substitutes.

A few years ago, we had a recurring nuisance trip in a motor control center. The FLIR camera showed one contactor running noticeably warmer than the others. Without the multimeter, we might have replaced the contactor. Instead, we measured current and found the load was unbalanced. The contactor wasn't bad—the upstream feed was. That single diagnosis paid for the thermometer and then some.

So when someone asks me to cut a multimeter from the budget, I push back. It's one of the least expensive tools on the bench and the one that answers the most questions. Keep it.

Where to buy Mitutoyo calipers without getting counterfeit?

The safest answer to 'where to buy Mitutoyo calipers' is: through an authorized Mitutoyo distributor, or directly from Mitutoyo if you have a corporate account. I know that sounds boring. The boring answer is the one that saves you money.

Counterfeit precision tools are still a problem. A few years ago, I nearly ordered a 'too good to be true' set of micrometer heads from an online marketplace. They looked fine in the photos, but I got an authorization check from our quality department and canceled just in time. A knockoff caliper might be off by a few thousandths, and if you're machining parts, that's scrap, rework, and a customer problem.

When you buy from an authorized distributor, make sure you get the calibration certificate. For gaged instruments, I also ask for NIST traceable calibration documentation before it goes to the shop floor. It costs nothing to ask, and it keeps the auditor happy.

Should we buy encoders from distributors or direct from the manufacturer?

For a one-off replacement? An encoder distributor, every time. Direct manufacturers are great when you're ordering volume or doing a new design, but many of them have minimums and lead times that don't work for an urgent repair.

We keep a running list of encoder distributors who carry the brands we use. When a machine goes down and we need an encoder overnight, I'm not calling three factories and hoping. I'm calling the distributor with stock, and I'm willing to pay their premium to get it. That's not a procurement failure. It's a calculated cost for certainty.

If you're buying more than 50 a year, then set up a direct account. But even then, keep a distributor relationship alive. They're the ones who'll save you during a supply-chain snag.

Is paying for rush delivery ever worth it?

Yes, when the cost of missing the deadline is higher than the late fee. In March 2024, we paid an extra $167 to get a FLIR TG298 thermal imaging camera delivered overnight. That was more than 30% of the standard price. Sounds painful. But the client's shutdown was scheduled for the next morning, and we were contracted to inspect their breakers before they energized. If we'd shown up without a working IR thermometer, the bill for that day would have been far bigger than the rush charge.

I have mixed feelings about rush fees. On one hand, they feel like a punishment. On the other, I've seen the chaos an unplanned order causes in a distributor's warehouse—so maybe they're fair. The lesson I've learned after six years of tracking invoices: uncertainty costs more than speed. If 'probably on time' means missing a deadline, pay for certainty.

What hidden costs should I check before buying test equipment?

Unit price is not total cost. Here's what I include in my spreadsheets before I sign anything:

• Calibration and certification — does the price include it?
• Warranty length and what it covers
• Training or onboarding time for your technicians
• Accessories: software, batteries, charger, carrying case
• Shipping, duties, and return shipping if it fails

I made a mistake early in my career: I chose a supplier based on the lowest quote and didn't notice they'd put calibration as a 'premium service.' That 'cheaper' quote ended up costing us more than the competitor who included everything. The same logic applies to thermal cameras. Software, reporting tools, and training can turn a basic FLIR E86 setup into a much more useful system. Add that line item to your spreadsheet before you compare quotes.

Should I buy the most expensive FLIR model I can justify?

No. I've watched companies buy top-tier thermal cameras and leave them locked in a case because nobody felt comfortable using them. The best tool is the one your team picks up.

Everything I'd read in the marketing said buy the greatest possible resolution and you'll never regret it. My experience with our orders says the opposite: the more expensive the camera, the more careful the field techs are about taking it into dusty, dirty, real-world environments. That doesn't mean buy cheap. It means match the camera to the task and the user. For most teams, the FLIR E86 thermal camera hits the sweet spot. For a simpler check-and-report use case, the FLIR TG298 thermal imaging camera can begin doing useful work the day it arrives.

And if you're still not sure, rent one for a week. That's a few hundred dollars, and it tells you more than any spec sheet.
