Which is the best vibration data logger?
As you have found your way to this article, I’m assuming that you’ve already purchased a vibration data logger or is looking to do so soon. And since we at ReVibe decided to venture into the world of vibrations and vibration loggers we have, quite naturally, reviewed a lot of other loggers before we introduced the ReLog. Now, we would love to share our thoughts and opinions with you to guide you along your way.
Naturally, we’re not unbiased in our opinions but we have a massive amount of respect for the competition we face in the market place and as with all situations: one product does not suit everyone. Hence, we hope that you’ll find this article useful when deciding which vibration data logger to purchase.

Reviews and rating of each logger
Before we get into the rating and reviewing part we would like to mention that our ratings of course will be subjective. You, as the reader, should review the facts presented above and make up your mind around the rating.
Convergence instruments VSEW mk2
The VSEK mk2 is the newest model of vibration data loggers by Convergence instrument which includes a 3-axis MEMS accelerometer that can sample as high as 4,000 Hz. The g-level has been set to 8g which is lower than their previous model where you could measure up to 16g. It might limit the scope of applications a bit compared to the older versions they offer. The internal memory is limited to 128 MB which means that you run out of memory after 17 minutes when sampling in one axis at 4,000 Hz. But, if you use the trigger functionality Convergence states that the memory capacity will last for up to 10 months when recording 3-axes at 1 min intervals.
Price: 492 €.
Rating: 3 out of 5.
The Swiss company is definitely one of the strongest players on the vibration data logger market and has extensive experience and a wide selection of loggers. Our favorite is the MSR 165 where we like the following choices (as MSR offers a wide range of customisable options): Lithium polymer battery, temperature sensor, humidity sensor, air pressure, 3-axes accelerometer with 200g-level and 1600 Hz sampling frequency and light sensor.
The logger itself looks to be very neat and easy to handle and offers an impressive range of choices. Our configuration ended up at around 1450€ but depending on how you configure the MSR165 prices start at 900€. The reason that we’re not completely in love with the product is it’s fairly limited sampling frequency.
Rating: 3 out of 5
Gulf coast data concepts USB-Accelerometer 3-axis
This is the simplest logger that we’ve had a look at and comes in at a mere price of 89$. For that sum you will get at small, light (55g!) and fairly neat logger. It can only sample at a maximum of 400 Hz with high resolution but can go as high as 3,200 Hz if you can tolerate a lower effective resolution. But what is a bit more impressive is the fact that the logger comes with a 8GB microSD card which means that you can log vibrations for quite a long time, which makes this logger ideal for first time users who doesn’t need high quality in terms of measurements but might just be looking for an instrument to detect movements/shocks.
Price: 89$ / 80€.
Rating: 3,5 out of 5
Endaq S3 & Endaq S5
Endaq, or Midé Technology as it formerly was called, is probably the market leaders in terms of track record and offers a wide range of logger configurations. We’ve had closer lok at the S3 and S5.
The S3 has a plastic casing with a few different accelerometer options where the lowest sampling rate is 3,200 Hz with two different g-levels at 16g or 40 g. The highest sampling rate possible for the S3 is 20,000 Hz with different g-levels of 25g, 100g, 500g and 2000g. Battery capacity lines up at 200-250 mAh hours and internal storage of 1GB-8GB. All in al, an excellent logger that with its maximum capacity has a good sampling rate but the battery capacity could have been a bit higher to live up to the price tag of 2000$.
The S5, which is Endaqs newest addition, provides a choice of 4,000 Hz or 20,000 Hz sampling rate. The battery size is larger for the S5 with 850 mAh of capacity and an internal memory of 8GB-16GB. In our opinion, this is where things get interesting with a bit more battery capacity and a decent memory size. However, the price tag is a bit higher for this one, and ranges from 2,250$ – 4000$.
All in all, two excellent vibration data loggers which allows you to get a logger that meets your needs but lacks when it comes to internal memory and battery capacity.
Price S3: 1,000 – 2,000 $ / 900€ – 1,800 €
Price S5: 2,250 – 4,000 $ / 2025 – 3,600 €
