Gutes teil
Das Gerät macht einen sehr guten Eindruck und fühlt sich auch hochwertig an. In der Hand liegt es angenehm und wirkt gut verarbeitet. Natürlich hofft man, dass die angezeigten Werte korrekt sind, aber nach einiger Zeit im Einsatz habe ich den Eindruck, dass die Messungen zuverlässig sind. Die Werte wirken konsistent und werden immer wieder gleich angezeigt. Insgesamt bin ich sehr zufrieden, daher volle Punkte.

très bien pour le prix
avec le recul d'utilisation, bon produit assez précis et qui fonctionne parfaitement pour ce qu'on lui demande de faire. très bien pour une utilisation non professionnelle.

Works well, quick delivery. Glad I followed The Coffee Chronicler's suggestion.
Seems to work as advertised. Very fast readings, simple to use. Good purchase. The only thing I wish were different is my water. My water is further out of my target zone than I hoped! Good tool, this meter. A tool I need as I work to improve my water chemistry for coffee brewing.

Easy to use, accurate
Very easy to use, ppm 0.5 is the setting you want for assessing TDS in terms of coffee. I trust it is accurate: tap ~330, brita maxtra+ slowly brought it down to 280-300, Tesco Ashbeck mineral water (Eden Valley, GB4) is around 80 I think. Looks and feels like proper old school scientific equipment (maybe it is!), which I like.

quality at a decent price.
Works like a charm. Fast reading (like 2 or 3 seconds) of ppm, no need to hold it for a century like a pH pen. The construction is durable, well-built. Came calibrated, which I like. Also, it has T°, which is really convenient with 3 non recirculating deep water culture buckets and a reservoir for a small flood table. Cooler res, happier plants. HM seems to be a reputable company, I would rebuy that item (well, not that I wish to do so) anytime. Buy with confidence. Excellent produit, j'ai été surpris de la qualité. Ne connaissant pas HM (et plutôt Truncheon-a-million) je m'attendais à un produit cheap en plastique qui craque quand on le prends dans nos mains. Rassurez vous, le crayon est petit, bien fait, résistant, rapide à la lecture (pas comme un crayon pH que t'essaie de tenir à quatres pattes dans une tente pendant que le PLQ est revenu 4 fois sur une décision tellement c'était long (comme cet exemple douteux)). Il est déjà calibré alors pas besoin de bouteilles de calibration, HM mentionne que ce n'est pas super nécéssaire de le calibrer souvent. Par ailleurs, il affiche la température ce qui est TELLEMENT PRATIQUE avec un système de 3 chaudières indépendantes en eau profonde. Eau froide, plantes heureuses. Quoique je ne le souhaite pas, je réachèterais (?) un crayon HM. Achetez le avec bonne conscience.
