- Great product but seems a bit over priced Review by Vibration Test Engineer
Price Quality Value
My issue with this product though comes with the cost and lead time. I think, in large part, due to the customization options each unit has to be made to order. As many people in the vibration testing market know, when we need test equipment we needed it yesterday. To wait 2 to 3 weeks is often prohibitive and costly as it can delay other high value aspects of our project. They also seem to really aggressively tack on the costs when adding sensors and storage options, to the point where I felt as though I was being nickle and dimed.
That all being said this product still provides great value over setting up the more traditional and complex vibration measurement systems. I'm definitely happy with this product but felt like it could be much better. (Posted on 12/31/2015)

If you order it with an external temperature sensor it can withstand up to 125C. The body of the logger itself can only be used up to 65C and even at that temp it shouldn’t be exposed to it for long periods. Doing so would permanently damage the logger as the battery would fail.
The MSR 165 logger is rated at IP67. The external accelerometer sensor is sealed in silicone and shares this rating. The MSR 165 logger is rated at IP67. The external accelerometer sensor is sealed in silicone and shares this rating.
The logger is available in two ranges, one that can monitor and record forces of negative 15 g to plus 15 g and another that can monitor and record forces from -200 g to plus 200 g.
The temperature range the logger can monitor and record using an internal sensor is -20°c to 65°c.
The accuracy is shown as a +/- value for each of the two sensor versions. Because temperature affects the accuracy of the sensor they also give you a temperature at which you can achieve the stated accuracy.
The accelerometer sensor gives you force data reported in g-force. The data can be viewed as numerical values or more commonly in a graph.
The sample rate is the rate or frequency the logger can be set to take a reading.
Because this logger is available with different types of sensors they give a sample rate for each type.
Acceleration: Up to 1600/s - The fastest the logger can record shock/vibration is 1,600 samples per second.
Temperature: 1/s to 12 Hours - Record temperatures anywhere from once per second up to once per 12 hours
Humidity: 1/s to 12 Hours - Record temperatures anywhere from once per second up to once per 12 hours
Pressure: 1/s to 12 Hours - Record temperatures anywhere from once per second up to once per 12 hours
Light Level: 1/s to 12 Hours - Record temperatures anywhere from once per second up to once per 12 hours
If you have any additional questions please feel free to ask.
The logger itself and the internal temperature sensor can operate as low as -20°C. If you purchase it with an external temperature sensor the external sensor can record down to -55°C however the body of the logger still would have that -20°C limit.
These loggers are designed primarily to operate independently of a PC. The PC is typically only used to configure the logger and download/view data. You can view recording values in real time while it's connected to a PC however you can only have one logger connected at a time.
The maximum size of the SD card is 4GB. If you are recording only acceleration at 1600Hz that will give you enough memory for 3 days but the battery life would only be good for 26 hours so you would be limited by that unless you left it plugged in. At 200Hz the memory would be good for 25 days but the battery only up to 8 days.
The only time the sensors are mounted externally is if you select it in the options while building the logger. The only circumstance where you would have a duplicate sensor both internal and external would be if you selected an internal temp sensor and an external rH sensor. This is because the rH sensor also has an integrated temp sensor with it. When the sensors are external they are connected to the logger via a cable.
