VOLTCRAFTph-100 ATC pH Meter Digital PH 0 to 14 PH Calibrated Standard Factory

Absolutly perfect as described received within 2 days of ordering. very accurate and reliable as compared with a slightly cheaper ph meter, this one though always was a bit more accurate than a different ph meter i also ordered and compared with. I would definitly recommend this ph meter as is really reliable picking up the slight changes to the ph. there are cheaper ph meters out there, but this is quality because it is accurate so no faults from me.

I test my fish tank water 4 - 6 times a week this meter is perfect for the job. its quick and easy to calibrate. it is a great bit of kit well worth buying if you want do a lot of water testing. you will need to purchase ph buffer 4 and 7 solution to set the meter correctly and also some DE-IONISED water for cleaning the probe.

Works well. Long battery life. Maintains calibration for a long time. Does not come with a storage buffer for the electrode when not in use.

Great little pH meter. Highly recommend it. Use it for checking my drinks when brewing. Like all pH meters , always store the probe in storage solution and never let it dry out. Regular calibration a must.

Works well and very easy to use. little calibration required.Good entry level ph meter- would recommend.Arrived on time

Just the job, does what it says on the box

excellent thanks

First: you'll need to buy, I should say MUST buy rather than should as otherwise you're left with a useless piece of equipment.1/ a 9volt battery2/ two calibration solutions or buffer, one pH7 and one pH4.3/ a bottle of distilled or De-aonised water.Your meter will also take 5 minutes to make a reading, and even though you might have a fluctuating reading as measurement never quite stabilize. but does it matter if, for example, your reading fluctuates between 8.39 and 8.62 and decides that the true reading is about 8.50? Up to you.
