PH Monitor & Temperature Meter 2 in 1 Digital Water Quality Tester Sensor Test Kit with Automatic Calibration/Replaceable BNC Electrode Probe for Aquariums Hydroponics Tanks Aquaculture Laboratory

So far so good. I’ve had it for over two months. People saying it can only do one thing at a time your batteries are low. If it starts fluctuating your batteries are low. I am very happy with this so far and will be buying another.

Works great, very handy. Be sure to take the plastic film of the back before you apply the sticker.Even though I cut the sticker in two, which saved me from the first mishap with the plastic film, it still isn't strong enough to hold it up so it falls down. I will have to use a superglue adhesive on the clamp. Then it will be great!It is so convenient to have this monitoring my microgreens system since the water PH tends to climb every few days.

Item is ok. It isn't very accurate for ph readings.

Product worked alright until it failed suddenly.Edit: Refunded full amount by manufacturer under warranty, rating changed to reflect product support.

Did arrive, testing find calibration unstable. Varies over time for unknow cause. Ensure you calibrate when device is at room temp. Room temp should be near standard day temp with consideration for elevation as needed. Tried margin hi lo and middle to minimize skew. Was plugged into battery back up with surge protection. Suspect internal components tolerances make the device subject to drift. I have made efforts to rule out ground currents etc.

Yes I could mention it's very accurate and inexpensive but I would like to say it's very easy to use and it comes with instructions that are easy to follow for calibrate.time will tell how often it's needed.hopefuly less than outhers I have had for my indoor garden.

So far this product is doing exactly what it says it would do. I just received yesterday and am currently using it. It says it works long term continuous use and all you have to change after a length of use is the probe so we will see. It was easy to calibrate. It even had a conversion chart on back of solution if your distilled water wasn’t 25c so that way you didn’t have to play games at trying to get it to the right temp you can calibrate it at whatever temp your water was at as long as the temp was on a even number example 10 20 30 not 26 18 or any of that. It was delivered faster than projected and so far packaging and and production were quality! Now if I wake up tomorrow and this thing kicked the bucket I’ll be upset. Also I’m planning on buying the $100-$200 system because I know you get what you paid for with these So I’m going to go with blue lab equipment due to I’m not just growing once and after 4 grows I could have bought the blue lab for the number of times I’ll have to buy this prob or replace this. I am hoping though for $40 bucks I can get one grow season of four plants out of this. If I get that I’ll keep it at five stars but if in two weeks it reads some wack readings I will require my money. The plus though is it did come with a one year warranty so maybe I’ll get two yields out of this bad boy only time will tell but as if this review I’m pretty happy with it for the time being it’s worth a shot for your first grow! Seperate meters that don’t take Remo in consideration are a waste of time so this works out and you can leave it in the solution.

For the price is very nice. Nice packaging and easy to calibrate, so far has been reasonably accurate (pH testing in the ±0.1 range), came with the power adapter I need,Did test a check solution with pH buffer 6.8 and it gave a stable reading at 6.8, recommend to everyone out there who needs a portable pH meter.
