Bluetooth Smart Tester AI3711 1

Calibration and measurement are straightforward. Once calibrated in the morning, I took several readings of aqueous solutions during the day, and the readings seemed to be OK. I knocked one star off the rating for the fact, that there was black mold in the storage cap for the tip upon arrival. I am aware that the tip needs to be kept moist, but mold can and must be avoided on a precision instrument like this. Now I am worrying about storing the device for longer time during the warmer summer season.

Arrive FAST, In 2 days. Excellent quality kit. Easy onboarding with a decent book and youtube video. The app is great but there will be a learning curve to figure out how to assign readings to a project. Right off the bat, I am getting precise measurments on my Kombucha and Jun fermentation projects. Considerably more accurate vs the Lamotte soil kit which bottoms out at 3.8 to the tenth with their PH water tools, but I need measurements as low as 2.50 to the hundreth. Also, the tannins in the (tea substrate) Kombucha significantly alters the sample color so the ph indicator solutions are not accurate, and my fermentations were off by at least 1 full PH. The PH60 read the precise value that exactly matches the research (I.E. Taste, bitterness, oder, CO activity etc). Excellent purchase for Kombucha, Jun fermentation, Water Kefir and Kefir Cheese projects I have going.

good price , fast shipping

Super coole sacher Sehr zufrieden!

This is my review of the Apera PH-60z (Bluetooth model) First off this is basically the same exact model of Apera's PH-60 it has replaceable sensors as well as different sensor attachments for things like food, pure water, etc. The only difference between this (PH-60Z) model and the regular PH-60 is the Bluetooth functionality and the device has a clear back case that allows you to see the internal boards and batteries. Functionality: I'm using this meter to measure PH in my plant feed/water I have tried all the cheap PH meters (looking at you Vivosun) made by the lowest bidder in China. None of them compare to a high quality meter like this PH-60Z. If you were only measuring TDS (total desolved solids) then I'd say go with a cheap one like Vivosun because the technology there isn't that hard. When it comes to PH don't trust those cheap ones they will be inaccurate and become uncalibrated fairly quickly. Don't make my mistake and waste money by trying to save money! If you are using this for growing in coco coir you only have a small window range of PH (5.5-6.2) to work with so plants can uptake nutrients. Don't waste months giving your plants improper PH levels because the cheap meter you used. Spend the extra coin and get an Apera like this one. You'll be happy you did. You could even get the regular PH60 (non Bluetooth for half this price around $79 US dollars. I payed $129 for this Bluetooth model. Bluetooth functionality: I went with Bluetooth so that I could connect it to the ZenTest app. When measuring PH you may have to insert the sensor into a small opening making it very difficult to read the screen. Thr Bluetooth version eliminates that problem by sending the data to the app. It also logs every single reading and fluctuations it detects. Customer service: Customer service appears to by USA based and has a direct phone number to support which is good in the unlikely event of an issue. Overall opinion: This is an excellent PH meter that will hopefully last me a long time and leaves me with confidence that if an issue were to arrise the company would stand by their product.
