Hanna Instruments digitale meter pH en temperatuur

pH is een belangrijke waarde in het zwembadwater. Bij een te lage pH-waarde kan het water te zuur zijn, wat huidirritaties kan veroorzaken. Bij een te hoge pH-waarde kan chloor z'n werking grotendeels of volledig verliezen. Daarom is het belangrijk om regelmatig de pH-waarde te meten. Met deze Hanna Instruments digitale tester kunt u zowel de pH als temperatuur meten. Op het duidelijke LCD-scherm zijn de waarden vervolgens af te lezen. De bediening is heel eenvoudig: er zitten slechts 2 knoppen op de meter. Dit is een aan/uit knop en een knop voor kalibratie. De pH-waarde wordt uitgedrukt met 1 decimaal achter de komma (bijvoorbeeld 7,2).

Unieke combinatie tussen pH en temperatuur

De temperatuursensor wordt niet alleen gebruikt voor het aangeven van de watertemperatuur, maar dient ook als compensatie wanneer u de pH-sensor gaat kalibreren (ijken). pH kalibratievloeistof is bij 25 graden Celsius exact de waarde die op het zakje staat aangegeven. Maar wanneer de vloeistof kouder of warmer wordt, verandert deze waarde. Dat betekent dat er bij de kalibratie al een afwijking kan optreden. Met deze tester is dat niet aan de orde, omdat de temperatuursensor de temperatuur van de kalibratievloeistof meet. De tester rekent dit vervolgens om, zodat de kalibratie 100% nauwkeurig is. Dit is uniek bij zwembad testers. De sensoren liggen allebei bloot, waardoor de tester een snellere reactietijd heeft.

Automatische kalibratie: plaats de sensoren in de kalibratievloeistof, druk op 'CAL' en de tester kalibreert automatisch.

Moisturizing, effective, pleasantly scented sunscreen
Style: Kids SPF 50, Size: 3 Fl Oz (Pack of 1), Style: Kids SPF 50, Size: 3 Fl Oz (Pack of 1)
This is the go-to sunscreen our whole family has been using for years. It feels moisturizing (but not greasy) and is easy to rub in to avoid any kind of chalky, white residue. The scent is subtle and pleasant, not the strong pronounced sunscreen smell that a lot of others have. Best of all, it is effective! The bottle received is different than the one pictured on Amazon, but we’re not buying it for the bottle, so that’s okay. :) Would recommend.

I hate sunscreens, but...
Style: Kids SPF 50, Size: 3 Fl Oz (Pack of 1)
I hate sunscreen in general--for it's texture and smell. But, being the palest family on Earth makes it a daily necessity. I was pleasantly surprised to actually like the smell of this product! It's a light fruity fragrance. It has a smooth texture like lotion and glided on my skin without being too thick or greasy and no white marks. A little goes a long way too! I could hardly believe I was putting on sunscreen and not regular body lotion. My kids had no issue with it either! They let me put this stuff on their little faces without complaint since it goes on so smoothly. Most importantly, this product did it's job and we were sunburn free. The tube is small--4 ounces--but I don't care because it's so worth having something that goes on easy and doesn't make us greasy and stinky. I bought several tubes--one for each member of the family. *If this review was helpful, please click 'yes' below. Thanks!*

It’s ok
Style: Kids SPF 50, Size: 3 Fl Oz (Pack of 1)
Doesn’t smell like anything, especially not fruit. Seems to work well- it’s what we use on our faces. I started using this all over on my daughter because their spray version is not good.

Overall this is a very good product
Style: Kids SPF 50, Size: 3 Fl Oz (Pack of 1)
I bought this because every sunblock I own eventually gets in my eyes and burns the living daylights out of them. I prefer to use something that isn't laden with chemicals, is cruelty free and reef safe so this looked like it would fit the bill and indeed, it does. It is a true "no tears" formula which I very much appreciate. As with so many zinc based sunblocks there's still a slight "Kabuki mask" effect but it isn't as bad as some of the other zinc products. I wouldn't go so far as to say it's easy to spread because it doesn't have a lot of "slip", doesn't glide like the non-zinc products. You do have to work with it for awhile to get rid of the decidedly chalky consistency but once you get going it seems to be okay. I think somebody else mentioned using a moisturizer before you put it on which seems like good idea even though this is supposed to be moisturizing. Would I purchase this again? I'm pretty sure I will because the "no tears" aspect of the product is important to me. I'll probably use it with a light carrier oil on my face first, let that oil sink in and then put this on top. I'll keep you posted on how that works out. Thank you, Alba Botanica, for being cruelty free and reef safe!
