Customer –
All very well, according to description and fast shipping, just saying the meters come without batteries and the TDS without calibrating solution, so it involves another extra expense, otherwise very well.
V***v –
Fast delivery, accuracy is not clear
M***. –
The store is handsome! The pH meter came to the RND after 10 days from the moment of order! The goods were sent from the Russian Federation, the Plus in the kit were batteries, which was very pleased. The only drawback is that only two bags for calibration go to the device: 4,01 and 6,86, and what you need for a full configuration of another 9,18 here it is not. Will come to order in another store. And so I advise everyone to sell this 325R-device and 99R delivery from Russia.

The parcel was divided into two parts, pH meter and TDs. pH meter came quickly, a week later and with batteries. But TDs waited a month later and there was no battery. The first parcel was handed by the courier from sdek, the second took in the mail. The store quickly answered all questions, there were no problems. PH meter works, it seems to be accurate, checked by the sulfur test TDs check until I can, no battery Seller recommend

Lightning delivery, to Yakutia delivered in 5 days. Sent from the Russian Federation. Batteries have already been installed
E***r –
Tester working. there are 2 kinds at first sight of the same instrument, so there is no O-ring between the body and the sensor. At the slightest shake, you risk turning it into a “magic” wand! I bring an example with and without!

The parcel came in a week. The devices correspond to the description. Work without problems. Batteries are already installed. So you can immediately proceed to measurements. It is a pity that only one device in the case and the second without. And so everything is super. Prodovets recommend.

The parcel came very quickly. The product corresponds to the description. In the kit, the tester itself, two batteries and two bags with a substance for calibration. Everything is laid in a plastic case. Seller Thank you!

7 days to the Ryazan region from the moment of order TDs and pH meters are equipped with batteries that are very cool. Complete with pH meter are 2 calibration bags 4.01 and 6.86. The instruction says that the pH meter is calibrated at 3 points 6.86 4.00 9.18. Calibration is necessary when removing or replacing batteries. Initially, my copy lowered the readings by 0.6, after the first calibration of 6.86, the second 4.00 almost coincided. The measurement speed of this pH meter is very fast. TDS meter readings check nothing, let’s hope it less shows true

Everything works, the calibration was successful, everything is clearly as indicated on the bags. Need to have distilled water for this. And there were no batteries in the pH meter. Very quickly all delivered by courier.

Very well presented the TDs in its protective bags the PH in plastic bag, but good readers I have checked distilled water and tap that pH 7,03 but residue TDS 0270 quite high. Recommended
V***a –
Got fast. Includes 2 calibration packages with reagents. There were no batteries. It is not quite clear how to insert (where a plus, and where a minus), there are no signs of this in the battery compartment. I put it on luck and guessed. Vrodi works.

The order was sent, quickly. Packed in pupyrku. True with batteries, in the description it seems to say that without one, leads to strange thoughts! I haven’t tested yet.
