Apera Instruments PH700-HF Benchtop Lab pH Meter for Strong Acidic Solutions (0 to 2 pH) and/or Solutions Containing HF Acid (up to 2000 ppm)

Excellent benchtop meter. Large and clear display and easy to read results. Excellent manual and laminated cheat-sheet card. Electrode stand is very convenient serving as that missing third hand. Reading stability and electrode health measurements after calibration very, very useful. Overall, a big step up from my trusty but aging portable meter. Highly recommended.

Surprisingly good pH meter for the money. Although only a single junction gel filled electrode, it had a solid response time and calibrates very easily. Additional specialty probes including higher end liquid filled ones are available and very reasonably priced. The screen is easy to read, calibration procedure is intuitive and the arm, while not articulated, is still very handy. Another nice touch is that the slope percentage is shown after calibration, which gives you a heads-up in case you fumbled the calibration or if the probe is on its way out. Overall I'm impressed by the value for money and would definitely consider one of their higher research grade units for more serious/professional lab use.

Unit seems a bit cheap in some aspects, but display is large and lighted. Unit also seems to be very accurate and not as complicated as you might think at first. While it’s not portable you will get accurate readings that seem to show where the hand held units with probes are slightly off. I will say after owning a couple of apera probes, ph 60 and then their BT zen unit that after purchasing this ph700 I would not purchase those again, they performed erratically and fell apart as they are poorly constructed. I hope this one will erase that feeling and last a long time.

The probe was so accurate I. The beginning but then was off by .3 all the time which isn't much however it's brand new. Maybe the temperature had something to do with that. Other than that easy to use and very popular. You cannot however replace electrolyte piece at bottom. You have to buy a new one.

As a sterile compounding pharmacy, I can not overstate how important it is to have a quality PH meter for our compounded preparations. The Apera PH meter has been a great addition to our process of ensuring we provide our clients with quality products. Will recommend it to any compounding pharmacy or labs needing to get accurate PH readings of their products.

Although some people say it is not accurate, their reviews sound like probe problems. For me, the reading is very fast and stable. I was a bit surprised the reading is super fast compared with others but so far there’s no problem with biological experiments. Will see how long it lasts. I bought 3probes already for the meter as I like it!

The instructions were perfect. Easy set up and calibration and makes measuring the ph of our cosmetic products a simple and accurate process. So happy to have made this purchase.

Received the pH meter and combination electrode along with the necessary components that included pH 4, 7 &10 standards, 4M KCl storage solution, electrode holder and detailed, easy to use set-up and use instructions. Was up and doing measurements within 15 minutes. Electrode easily calibrated and appeared stable during use. Pleased with performance so far.
