Review: Great Instrument for Turbidity - We had been looking for a more economical and reliable turbidity meter to replace our aging HACH units and this fits the bill perfectly. We have 4 or 5 of these now and they are easy to use and the case it comes in is also great compared to the huge "tacklebox" style other brands come in. The replacement standards are also easy to order and use and it comes with plenty of sample vials for tests in the field. Very happy so far. Review: Won't turn on out of box or after charging UPDATE: 3/2/21 - I would love to write a review about the performance, however, it is yet to turn on...Plugged in with the USB cable and charger head that came in box. No sign that's it's charging and all buttons unresponsive. The mute blue screen. Let's see how their support services work. UPDATE: Their customer service returned my email and they sent out a replacement unit free of charge. It works and looks to be a good device for our needs. Probably best to order straight from their website and ask that they check the unit before sending. Pleased with their resolution. ## Features - Tungsten filament lamp light source and 90Β° scattering method, compliant with the U.
