Three days to volgograd, great!!! All as in the picture.

To the rostov region-4 days, very quickly, ordered delivery from russia. Delivered sdek. All whole, complete set-device, two calibration packages, case and instruction. The device is working, but the batteries are sown-it is better to change, because each time they are replaced, the device needs to be calibrated according to the new one. And yes, it is better to calibrate. Water after the domestic 3-stage filter showed 7,6 ph, distilled-6.5 ph. Within, but better calibrate. Normal instruction on the Russian is easy to find online. Example below

I had to buy new batteries! The ones in the printer were killed.

It came to samara for 4 days, the batteries were included! Works but calibration did not do

Tavar received very quickly. Included were batteries, an order from the russian federation. The readings are stable.

lost in transit. Seller refunded my money. Not seller fault. It's India post's careless attitude which misplaced my package and no response when asked.

Delivery shcha week, all the norms, only not enough another bag for calibration, but i will get it somehow, the description also this bag is not, so 5 stars

Article looks decent from, there stands alone not at what battery there are in need. Tip for the seller.

In principle, two are enough for household needs. The solution for calibration can be reused by filling in separate jars.

Everything came quickly, turned on, in the work on measurement and calibration has not yet checked. Uses 2 lr44.

Ph water meter came very quickly to moscow. Packed in a duster film. Manual for use and two bags to adjust the ph in the kit. Two bars r46 need to buy. Thanks to the seller for the shipping speed and quality goods! Prosperity to your store!

Very fast delivery, courier cdek (5 days) to murmansk, the work was not checked yet.

Ordered 2 pieces, came quickly. Packed well. But i did not understand the angry in the same volume of glass. One shows 6.4 other 6. 8 their colibe need or this is such a jamb in the devices themselves. i will understand. After the review, i will add.

You become so behind your rags aangezeten to indicate that something delivered is. I have not yet had time to test or pH meter also good and proper speed ratings indicates. The delivery was very quickly. 8 days. Class :-). 5 stars for the neat fast delivery. Not for the operation. There I know yet nothing from. The pH meter looks very good and neatly out. I go there so much from that he functions properly.

I haven’t tried it yet. Arrived really fast. Recommended

Delivery 5 days from russia. That makes you happy. But here is the kit as for me not full. There is not enough another bag for calibration. At 9.18. Because of this, i think there may be problems with accuracy. Well, the case of the corner suffered a little. How to measure i will add a review

It was demoro super little (chile) had already bought another and 0 drama.

Works, i will not calibrate, t. K. It doesn't seem like the truth. Tap water 6.8, filtered 7.1, boiled 7.7, soda solution 8 with something, lemon 2.2. For evaluation will come down. Lifhak: the battery compartment can be inserted with a burning side so that the board on the input into the contacts and the battery does not sit down during storage. But see that there is definitely no touch, otherwise the polarity will be confused. Yes, on the lid is the designation +/-, but you need to look)

All norms, only included 2 bags for setting, you need to order more

Everything has reached in a month in kazakhstan, the city of aktau. Everything is wonderful, only without batteries.

Package well received. No batteries included. Too bad. We will see the use.

Good seller recommend.

I bought for 8,90 dosttavka from moscow a bright, the device works, the batteries did not put, and with them, still the slag is stuffed. I bought it in moscow. For 75r. Enerjuhi, lr 44.

The parcel came quickly, but as always our post of russia did not even allow to warn me that the parcels came. Here is a double opinion, the seller sent double track code, one for china, the other for russia. Russian post could not understand that the code of russia, you can see parallel to china. I had to separately print the code of russia with a receipt and take it to the post office and about a miracle! Package in place! Pull on the us.

The seller is sociable thanks to him for his promptness. For this price is not even bad and most importantly quickly. Thanks again to the seller! The product is excellent! Seller recommend!!!
