    Good product, fast shipping. Great seller, I will highly recommended!!

    The TDS-3 is a genuine HM model (not the fakes sold on ebay/Amazon – I should know as I own two of them – utter rubbish and an absolute waste of money).
    The meter is factory calibrated to 342ppm NaCl and was tested using a commercial 342ppm solution. The meter recorded an exact 342ppm upon testing. The TDS-3 can also be calibrated manually.
    If you’re looking for a TDS meter please do yourself a favour and buy the real deal as the fakes I own are up to 200ppm out. This level of inaccuracy makes your readings more of a guess as opposed to the accuracy the HM TDS-3 provides.
    I paid for the product in the morning and MDC Watersent the product out an hour or so later – their communication was first rate and shipping very fast. Can’t complain about any part of my dealings with this company.
    I certainly recommend this seller and this genuine product.
    (….and let me repeat – please purchase authentic HM TDS meters to save yourself money and to be confident in your TDS readings!)
