The media could not be loaded. When I purchased the Protmex HT602A SPL Meter Decibel Meter, I had no idea what I was getting into. I initially bought this sound measuring tool to measure the noise from a soundproofing cabinet I built for my computer and to test various other objects and their noise levels. I didn't realize just how limited the actual usage of this product would end up being over time.

I thought owning "some testing equipment" for reviewing products like computer fans and sound dampening materials was a great idea. The price point of the Protmex HT602A was fair, considering its functionality and effectiveness. It had a great handfeel, and I was impressed by its performance. I tried to find more devices made by Protmex but discovered they don't really produce many other products besides this sound meter and couple of other things. Even their design resembles lots of many other generic items on Amazon.

I realized the device is was essentially a generic product with a generic plastic label. The packaging is plain and unbranded, with only "ENVIRONMENTAL METER" written on the box. Despite its generic nature, I found the price to be reasonable for its purpose, and it was sensitive enough for my limited usage. It was easy to use and maintain.

The product's actual application was where it fell short. I kept it around for as long as I could, but I never found a real use for it, contrary to my initial expectations. It just sat unused in its bag, a constant reminder of an impulsive purchase with good intentions. Eventually, I returned the product "“ not because of any fault in the product itself, but because I couldn't justify spending money on something I didn't foresee using in the future.

In my experience, this device was more of a niche product. While it appeared well-built and had a bright, industrial design, it just didn't provide me with the information or had the overall usage I had hoped for. Your mileage may vary with this type of device. I didn't even really get a solid answer if my sound dampening case really made that much of a difference, even with several layers of sound dampening material.

For what it's worth, the product was one of the better generic testing devices I have purchased on Amazon. I just wish I had found more uses for it. It is by far one of the most easily readable screens, awesome backlight, top notch build quality, and positive handfeel experience was all positives about the product. If I ever to ever have an immediate need for a decibel meter in the future, I would consider picking this one up again. It was affordable and of good quality. I would recommended it if that really matters to anyone.

It has a nice, clear, large display. The backlight is great. Accuracy? That cannot be determined unless the tool is tested against a known 'standard' tool. On 'fast', the db reading on the tool certainly changes quickly, which leads me to believe it IS sensitive, but says nothing of the accuracy.

It will be fine for my intended use: How loud IS that fridge, anyway? Is yours louder than mine?

One important note: The temperature function is essentially worthless. After having the tool 'on' for minutes, I wondered why it measured my house temp (66º) to be 74º. I held the unit over a 500W halogen lamp. The temp reading did not change. I let the unit sit on a warm oven until the temp reading stabilized at 76º. I then put it in my fridge for 30 seconds, stopwatch timed. The unit read 75.8º.

I contacted the seller because that indicated a faulty gauge. I was advised, '...feedback from the factory, if the temperature difference is large, the temperature may take ten minutes to react'

Quite not at all specific.

IF a temperature sensor that works in maybe a ten minute timeframe is OK with you...this tool will do.

I have an IR temp gun that measures a temperature as fast as I pull the trigger. Most temp guns do that. Wait ten minutes? Ridiculous.

I bought this tool for the db function. Considering the display size and the backlight, I choose to keep it for that purpose.

Using it to check gun and rifle db with and w/o suppressors.

All its functions are well conceived and implemented its designers.
Easy to use . Does what it is supposed to
