2 in 1 Temperature pH Monitor Meter Tester Sensor test Kit 0~14.0 pH Automatic Buffer Recognition BNC electrode Probe for Hydroponics Aquarium Lab Testing Food Drinking Water pH of saltwater/seawater

I bought one of these in tank Ph meters along with a different one that does the same, at the same time. This one was calberated properly when it arrived. The other one I to recalibrate. Placed them in the tanks and the other one wouldn't read the temp correctly from the get go. This one was spot on with temp and Ph. I have a hand Held Ph meter also that I test with and it matches this meters readings.. The other meter started messing up on day 5, it stopped working altogether within a week. I returned it and bought another of these meters. They have been working perfectly. Love that I can now easily test my Ph levels with a touch of a button. Also like that they work with batteries. Now if they could come up with an In tank Gh and Kh meter. My shrimp would be happy!

Item calibrated straight out of the box, no issues. Seems to be holding a steady PH and temperature two weeks after purchase, I have always kept the probe submerged in water to prevent it from degrading. I can't even complain so far since it's so cheap, I didn't want to invest straight into a BlueLab Guardian so this is a better alternative for just starting DWC. I'll keep this updated!

I have now bought 6 of these for our labs. They appear to be accurate enough for the work we do when properly calibrated. Cannot vouch for super sensitivity, but if you need the pH within + or - about 0.05 - 0.1 accuracy you will be fine with these. They are easy to use and so far seem to hold up well. My application need is for nutritional supplements so measuring pH with 0.1 accuracy is plenty for us and these hit the mark.

I bought 1 and it seemed to work good for almost 2 months.then I bought a 2nd meter and it lasted 2 days and bought more calibration solution and it would not calibrate.then had a replacement sent and this one reads almost 1.00 off .I will never buy again.my plants are destroyed because the pH meters don't work right .I would recommend don't buy this and go find a meter that works as it's supposed to.the worst customer service ever .they offered me coupons instead of making it right .so looks like I'm out $80 and the company does not care at all .

This monitor is ideal for the strict PH regimen I have to follow. It is very accurate and easy to operate. The directions are clear and it comes with the calibration materials. I was impressed. I use it at least 2 times a day to keep good PH levels. The temperatures I am not to worried about but it tells me that as well if needed. Very nice tool and would really recommend it to all at this price point.

Seems to work pretty well. Issue with the equipment is there are no mounting suction cups for inside aquarium use. I get it it is not solely designed for aquarium use. Still anytime used for pH monitoring it will be inside some container.

I’m gonna give it five star because it’s five star I’ve been having it for years to make it work exactly like it is. It has to be constantly on the solution. You cannot take it in and out. It has to be wet 24 seven it will take a day to read the exact but when he does, that’s perfect

For those that have bought several Ph monitors in the past, you know that the price point for something built for longevity is over $100. Replacement double junction probes alone start at $60-$70, so walking into this I didn’t expect a lot. I ordered two and was impressed with the build quality of the unit. It’s solid and heavy, and actually feels in the hand to be a better build quality than other monitors for $80-$90 that come with a probe. The calibration was so easy I did it a few times because I thought I was doing something wrong (the unit self-senses the area it needs to calibrate to depending on the calibration fluid). One unit worked well and is still working well a couple of months later (with the original probe, but I plan to replace the original with a double junction probe down the line). The second unit appeared to short out when the temperature probe and the ph probe were I. The same water (I took out the temp probe, it read ph, I took out the ph probe, it read temp, I put both in, I got “——“. I contacted the company about the faulty unit and they had be do a few tests over a couple of days to determine what was happening with the unit. After a few days the company confirmed the unit as faulty and replaced the unit. The replacement I received I’ve been using for 3-4 weeks now and no issues whatsoever. Remember, you get what you pay for, and I’ve not seen too many places that sell a unit with a probe for this price. I’m very pleased with the purchase.

It took me less than 10 minutes to set up and fixed to my aquarium. The supplied hangers don’t fit as my tank has a lid, but a couple of suckers worked great

buen phmetro

水草水槽のｐH変化測定をするために購入しました。 開封した状態で、標準液を計ったところ、だいたい正常な値を示しました。ちゃんと予備校正して送られているようです。 検出部は保存液につけておける容器もついていました。 以前使っていたハンディタイプの黄色い1000円くらいのｐHメーター（中華製？）を3年使っていましたが、壊れたので購入しました。 このｐHでも、0．01刻みで測定できたのですが、表示が安定するまで4～5分かかったので、測定水をくんで静置する必要があったので不便でした。 同形の、ブルーの日本で検査した、0．01刻みで4秒で計れると記載のあるｐHメーターをアマゾンで購入したのですが、0.12とか0．14刻みでしかｐHを計れなかったのですぐに返品し、これを買いました。 このｐHメーターでも安定するまで4～5分かかりますが、検出部を水槽に入れたままで放置できるので、ｐHの変化を簡単に測定することが出来ました。 ｐHが0．01刻みで表示されるので微妙な変化を追うことが出来ました。 水草水槽の水を連続測定した結果、CO2を添加すれば徐々にｐHが下がること、CO2添加をせずに照明をつけるとｐHが上がる様子などが精度良く測定できました。（グラフ参照） 検出部にコケなどが付かないように、測定しないときは取り出して置こうと思います。 良い点 ほかの同様のものが、2万円以上するが、これは価格が安く、検出部だけ水につけたまま0．01刻みでｐHを計れるメーターです。 表示が大きくて見やすい。 バックライトがつくので暗くても読める。 小さいコイン型電池ではなく、単３電池なので交換しやすく使いやすい。 ｐHの検出部が交換可能なので、劣化すれば新しい物に交換できる。（アマゾンで1200円程度で売っている） 耐久性については購入したばかりなのでまだ分かりませんが、数年使えることを期待しています。

Much easier to maintain ph levels in my hyrdoponic tower garden using the meter as apposed to the test strips provided with the garden.
