In my role coordinating rush orders for industrial clients, I've learned that the phrase 'what's the best tool?' is almost always the wrong question. The right question is 'which failure mode am I chasing?'
I've handled 200+ rush orders over 12 years. Last quarter alone, we processed 47 emergency shipments with a 95% on-time rate. When a plant is down, customers don't need a sales pitch. They need an answer that maps to their situation.
Here's the thing: there is no universal answer. There is a good answer for you, and a bad answer for a different team down the street.
I'd rather spend 10 minutes explaining options than deal with mismatched expectations later. An informed customer asks better questions and makes faster decisions. So let's walk through the three situations I see most often.
First, Separate the Three Scenarios
When an emergency call comes in, I ask one question: do you need to detect, monitor, or verify?
- Detection: you know something is wrong but you can't see it.
- Monitoring: you need a system that watches continuously, even when nobody is on site.
- Verification: you need a measured number before you can release product or get sign-off.
The tool follows from that. Not the other way around.
Scenario A: Detection - You're Chasing a Hidden Fault
This is the most common emergency call. A breaker keeps tripping, a motor is running hot, a steam trap is passing. You have one shutdown window, and you need to find the bad spot before it costs everyone the night.
For detection, a handheld thermal camera is the practical first tool. And this is where people get hung up on specs.
From the outside, it looks like more pixels always wins. The reality is more nuanced. Per FLIR's published datasheet as of January 2025, the FLIR E96 thermal camera resolution is 640 by 480 pixels, which gives you 307,200 temperature points per frame. That is plenty to spot a bad connection on a busbar or a failing bearing while you're still standing at a safe distance. I'll take that plus good thermal sensitivity over a higher pixel count with a narrow field of view any day.
In March 2024, a food processing plant called us 36 hours before a scheduled outage. They had 12 hours of actual downtime to find an intermittent motor overload. We sent an E96, and the electrician scanned a motor control center from six feet away. One lug was running 18°C hotter than the same connection on the other phases. The fix took about an hour - or rather, 90 minutes with safety paperwork. Missing that would have meant a $50,000 penalty clause for a night of unplanned downtime.
A Reliable Partner: the 17B+ Digital Multimeter
A thermal camera tells you where to look. It doesn't tell you whether it's safe to touch. The 17B+ digital multimeter has been my go-to for the electrical side of that job for years. It's not flashy. It is reliable. Check for zero energy, confirm voltage, then open the panel.
Look, I have mixed feelings about recommending a meter by name when we also sell FLIR test equipment. But a tool is a tool. The 17B+ does what it says, and I see it in service vans because it survives real work. Use the camera to find, use the meter to confirm. That combination is faster than either one alone.
Scenario B: Monitoring - You Need Continuous Eyes, Not a Single Image
What if the problem only happens at 2am? Or what if your customer wants proof that a critical asset stayed below a threshold for a week? A handheld camera is a visit, not a solution. That's when I recommend an FLIR A-series thermal camera.
Some catalogs write these as A-thermal cameras, because they're designed for permanent mounting and continuous data logging. They stream radiometric data and can trigger an alarm when a temperature threshold is crossed. The A-series has the same physics as the E96, but in a package built for automation.
I have mixed feelings about automated monitoring. Part of me misses the hands-on routine of walking a line with a handheld camera. Another part remembers all the times a fault appeared only after the shift ended. An A-series camera doesn't get tired, doesn't forget, and doesn't leave early. It's not ideal for every site, but for critical equipment that can't shut down, it's close to exactly what we needed.
People assume monitoring is overkill until they miss the 3am event. What they don't see is that a fixed camera costs less than one unscheduled trip in most cases. At least, that's been my experience with industrial plants.
Scenario C: Verification - You Need Numbers, Not Images
Thermal cameras are diagnostic tools. They measure temperature differences and radiation. They don't measure shaft diameter, and they don't measure liquid volumes. When the emergency is about dimensional tolerance or repeatable sample preparation, you need a different kind of instrument.
A Digimatic Micrometer for Close Tolerances
A digimatic micrometer is one of those tools that doesn't get much attention until a machined part won't fit. It gives you a digital readout down to 0.001mm and removes the guesswork from reading a mechanical micrometer. For a quality manager staring at a deadline, that number matters more than any thermal image.
In 2023, a plant needed a second reference measurement before rejecting an incoming batch of bearing journals. We delivered a digimatic micrometer the same day, and the QC lead confirmed the bearing journal was 0.004mm out of spec. The part would have failed anyway, but without the micrometer they were arguing with the supplier. With it, they had a number.
How to Use an Eppendorf Repeater Pipette
Lab workflows are a separate world, but the same logic applies. If you're dispensing a reagent into 48 vials under time pressure, a standard pipette is slow. An Eppendorf repeater pipette lets you dispense multiple fixed volumes from one tip without resetting between each tube.
How to use it correctly: attach the Combitip, rotate the setting to the volume you need, purge the tip once to remove the air gap, then press the trigger for each dispense. That's it. The word 'repeater' means you're not changing the volume between every tube. I can't speak to every lab protocol, but I've helped enough rush deliveries to know this: when someone asks for a repeater pipette, they are always, without exception, up against a batch deadline. Respect the pre-rinse step. It's not optional.
How to Decide Which Scenario You're In
Still not sure? Here is the decision path I use when I'm triaging a rush order:
- Are you looking for the location of a fault? Start with detection: a handheld thermal camera like the FLIR E96, plus a multimeter like the 17B+ to confirm safety and electrical state.
- Will the fault happen while nobody is watching? Add monitoring: an FLIR A-series thermal camera to collect data around the clock.
- Do you need a tolerance measurement or a repeatable liquid volume? Use a digimatic micrometer or an Eppendorf repeater pipette, depending on what you're measuring.
My experience is based on roughly 200 rush orders in industrial maintenance, electrical contracting, and lab supply. If you're working in R&D or building diagnostics, your context may be different. But the framework should still hold: detect first, monitor if needed, verify before you sign.
And if you're still not sure, ask the question you're trying to answer. That, in my opinion, is the only honest way to choose a tool. A lesson learned the hard way, more than once. I'd rather spend 10 minutes explaining options than deal with mismatched expectations later.
