Apera Instruments TDS20 TDS-meter, digitaal meetapparaat met temperatuurweergave (1% nauwkeurigheid, ± 0,5 °C, waterbestendig, ATC, draagkoffer)

This is money well spent. I paid the full price for this device, just like for Apera Instruments' EC-meter, and I have no regrets. I study Horticulture and have high requirements in terms of accuracy. As expected from a quality tool, you/we get two bottles of calibration fluids with it. You/we also get a very study, compact, water resistant carrying case with a handle with it. While being accurate enough for most professionals, I believe the device is still easy enough to understand/calibrate/use for any amateur thanks to the manual and especially the foliated one-page-quick-manual. Extra points for the included batteries.I highly recommend buying this product since you will most likely not get even halfway reliable results with most cheap, competitive products and end up buying a proper device anyways.

TSDメーターを2本持っていますが、測定結果の差にひらきがあり過ぎるので、この商品を購入しました。購入するに当たっては、pHメーター（PH-20）を持っていて精度も良かったのと、自分で校正出来る点を考慮して決めました。購入したばかりなので耐久性は分かりませんが、測定結果は満足いくものでした。校正の手順も、クイックマニュアルに図解で説明があり分かりやすかったです。

Mesure simple et rapide, contrôle et étalonnage aisé sans devoir jouer du tournevis grâce a la reconnaissance digitale et les solutions d'étalonnage livrées dans le coffret.

Amazing product. Easy to use.

I love the ph meter and am glad to now have TDS meter. I had no idea just how hard my tap water. Super super useful. I may very well add an EC meter to my little Apera collection next.
