Digital sound level meter MS6700 30 dB - 130 dB

I received this sound meter today as a replacement for another sound meter that failed. I really liked the look feel of the last meter that was smaller but it went wonky within a few days and now I have this much, much better sound meter.At the unpacking, the first impression is; "Nice case." It comes with it's very own, vinyl, carrying case to hold a spare set of batteries, an electric test adapter and the sound meter itself.When you hold this in your hand the first thing you'll notice is that "IT'S LARGE" and when looking at the face of the unit you'll notice that it has a nice control panel and layout. I'm not going drop it, but it has the feel and weight of a piece of equipment that can withstand a three or five foot drop test. I'm not recommending one try doing this but that's the solid feel one gets when holding this sound meter.If you have a calibrator for a half inch microphone column on hand, the unit has a calibration port for calibration purposes. One would use a fine jeweler's screwdriver to turn the deeply recessed calibration screw.One can easily change the monitoring range and from there the unit will automatically choose any necessary range changes. The range of the unit is 30dB - 130dB, five measuring ranges, each with a fifty dB range. This sound meter has a +/- 1.5dB tolerance.The back-light stays on for only five seconds and personally, I find this to be a pain if wanting or needing a longer on time.The sound meter comes with an on screen clock and on the back of the unit, has a 1/4" tripod screw.The unit has measurement AC/DC outs for recording purposes at the bottom end of the unit as well as a 9v input port should one run out of the six needed, 1.5v, AAA batteries.I used this unit today to aid in the EQ'g of our sound system and to measure it's output during a cable provided movie. Overall, other than it being a very large case and the backlight feature turning off after five seconds, I was very pleased with it's performance and impressed with the professional look/feel of the unit. This is a unit one would feel comfortable bring into a professional environment such as an auditorium, machine shop or any loud venue to do measurements and not worry about being made to feel they've come with anything but professional measuring gear.I have used Radio Shack meters and several Amazon purchased meters and I feel comfortable saying this is an excellent meter, at a great delivered price which I feel comfortable recommending. If over time, something comes up, I'll come back and to the good or bad, will amend my comments.Hope the above helps in your decision making process.

This is a good sound meter. It works really good. The light is green and bright. It also comes with a very nice case that helps to keep it in good condition. The reason I am not rating it 5 stars is because I picked it out for the auto range and no matter what I do I can't find auto range on it anywhere even though the specs clearly state that it has auto range. It took me a little while to find out how to set the clock on it, you hold the max button while turning it on, then use the arrows to set and max to move between fields, then turn it off when finished. I tried holding down different buttons and stuff to see if I could get into auto range, but, it didn't work.

Unit is deceptively large based on photos; not at all pocketable. Directions and labeling on box all in Chinese, but simple enough to operate. Would strongly suggest getting a more compact unit than this.

Since I had never used a sound meter, I really appreciated and relied on the very professional reviews and thank them all for their observations and suggestions. The MASTECH MS6700 appeared to operate correctly. I agree that having the light go off after a few seconds is distracting, especially when monitoring an evening event. I liked the MAX feature because the reading only increased with the sound and did not return to a lower number until manually instructed. Now that I know more about the process, I wish the meter also had a function that averaged the noise levels during the one minute measurement periods. Although the meter is made abroad, the instruction manual is dual language, and the instructions are easy to follow. Customers might want to look into accessories for this meter in order to get the most efficient use of it.

purchased this 8-27-14 used appox .6 times for maybe 3hrs.Worked fine 12-19-14 then 12-20-14 just quit.Changed batteries,STILL WONT WORK .Not a happy customer.Also it is not eligible for return!!!!

Very good item, however no chance to change internal clock.

The device works well enough. Instructions for use were written by someone who uses English as a second language, so are somewhat difficult to understand. Included is a warning that a year of hard use may require the device to be re-calibrated. Users must contact the manufacturer for the recalibration procedure; recalibration apparently requires the use of a standard sound or signal generator. These two facts should be included in the information about the device on the Amazon webpage.

After comparing the similar models on the market (Galaxy CM-140 CheckMate, Extech 407732, etc.), this one seems to be the best value. All these models are sensitive to low-frequency models, important for testing bass frequencies (some less expensive models do not range low enough in Hz to test low frequencies properly). I chose this one as it includes a useful backlight, and the price is substantially lower than those other two models. Otherwise, features are comparable. Also, this model includes a nice hard vinyl protective case; as far as I know, those other models do not.The device arrived and I am very pleased with using it. It is probably made in China, unfortunately, but I believe all these models are. However, the build quality seems good. The unit is quite large, and weight is substantial. The display is very clear, and the green backlight is excellent. Both A & C weighting are selectable.Highly recommended meter.
