Review on 🔊 Professional 30DB-130DB Backlight Measuring Instrument: Accurate Sound Level Monitor by Keith Aluguvelli

Still have the older Temma, ok but a bit dated (only reads A weight grades and sucks batteries like it was done with vacuum tubes). A good Radio Shack with an A/B weight has been stolen from the control room of a public TV station. So I needed a replacement and after much searching the SLM-25 looked very promising. It met my expectations and the data logging feature is a big plus. Well, for most users. The software runs on Win. 7 and 10 Pro but I mainly use Linux Ubuntu Studio. With the latest version of Ubuntu Studio & Wine, sftwr loaded the page; However, these are not handshake instructions. It also didn't uninstall, so I had to go through the Wine files and remove it manually. I installed sftwr with win. Installer and then let's try the MS Installer. whenever I find the courage to do so. I could also try installing sftwr using PlayOnLinux or Lutris since they emulate hardware drivers (like game consoles or controllers); and the SLM-25 sound pressure level meter belongs to the sftwr/hrdwr device control category. I have 2 problems with long term surgeries. I don't know who actually designed or built this model of sound pressure meter (Gain Express, Triplett, Danoplus. They all look identical to the SLM-25) but one reviewer stated that it has a coin cell battery that holds or operates the in meters. That when the battery died, the meter died too; clock and everything. Replacing the battery was not reset, as he believed it should be done at the factory. My other concern is recalibration. Both Gain Express and Tekcoplus will sell you a microphone meter tone generator calibration tool, assuming both brands are the actual designer of the meter model. This calibration tool is quite expensive (+/- 3.25 times the price of the meter), but I didn't see a port for external tuning; no tabs on the sftwr side for that. I might be within the block but at this point; however. Good for the price; no triplet (2x SLM-25), this SPL meter can and should meet your and my needs and expectations with, shall we say, great satisfaction. at least a few years? (or until someone else steals that one). Oh yes, one more thing. Batteries are slightly wider than traditional disposable batteries. They do not fit in the battery compartment. So I use a plain old external cellphone charger/power supply in combination with the batteries that come with it; via the USB port and when not connected to a PC. I suspect and hope that by using it this way, and since it turns on automatically, I'll save juice in the meter-hours mentioned earlier. The SLM-25 has been a great purchase so far and I would highly recommend it.
