Apera Instruments PH910 Benchtop Lab pH Meter Kit with LabSen 211 Refillable Glass pH Electrode

I purchased this meter to replace an Oakton meter that stopped workingI have a smaller handheld meter from this manufacturer and figured I'd give their bench model a testThe large bright easy read display is great the on screen instructions for calibration work well for someone who's new to PH Meters and testingThe onboard storage of test results is very useful for me and being able to export those to a computer or a flash drive seems like it would be great but I haven't tried that yetReadings from the included electrode are fast and stableThe price point and features for this meter make it a perfect fit for me I would recommend it

This is the 3rd instrument I've requested from this brand, as two of which were given to my grandpa last year have been working great !To be clear, it is being used at his farms (It started as just a family farm for recreational purpose of his, but it's actually became so much more than that and it's huge now to be honest).Now the head of gardeners(?) who mostly helps my grandpa manage the various plants and more, also told me that Aspera was a great brand a while ago. which is why I started requesting instruments from this brand every time I see them.Well compared to the portable digital PH meters they've been using, this was a much needed upgrade for sure on so many levels not to mention the accuracy.I cannot obviously mention how this would be measured for your purpose like a scientific laboratory setting from the first hand experience, but I believe it would be perfect for almost all purposes.In light of other Aspera instruments that've been in use, I expect this to last long as well :)Overall, another quality instrument from Aspera, and I am again a happy customer.

A great instrument from a well-known brand. Perfect for an in-home lab. Shipped and delivered quickly.

The benchtop pH meter by Apera Instruments, is a good quality, accurate, affordable way to get pH results combined with other abilities to increase its usability. Here are some of the things I’ve learned while owning it and things to consider before buying.I. Quality – It’s made of what appears to be solid, good quality materials, that I would put in the upper-middle level of the quality scale. This isn’t a top of the line machine, but the cost reflects this. I would guess that it should last for a good amount of time considering the quality level and other machines that I’ve had from this company.II. Usability – This is a very easy machine to get used to, with its intuitive software. It makes getting readings quick and simple. The size and layout have made it very easy and convenient for me to use it and the readings are quick and accurate. Apera makes good quality accurate machines that seem to hold up well over time from my experience.Overall, this has been a great addition to my testing abilities. It’s easy to use and has repeatable accurate, leading me to be very happy with my choice. I’ll be sure to update this review, if I ever start to have problems.You can trust that this review is simply my honest opinion that is attempting to provide you with helpful insight that I wish I had before I picked this product. Hopefully it was helpful in your decision.

Good instructions except for how long the probe be exposed to air before it must be submersed in liquid.

Apera is a well-respected name in PH measuring devices. I’ve been using an Apera PH20 meter for the past three years. Its probe is not replaceable, and it has lost its accuracy. The Apera PH910 Benchtop Lab pH Meter is not only its replacement but a valued upgrade.In winemaking, the PH level tells me a wine’s acid level and allows me to make adjustments before bottling. A low PH reading, one below 3.2 for example, indicates a high-acid wine. High acidity adds a bite to the wine that is desired to offset a wine’s fruity character. For example, Sauvignon Blanc and Riesling fit this description. A wine’s PH level also lets a winemaker know a wine’s aging potential and lets him or her know the sulfate level needed to protect the wine to enhance its shelf life. High PH wines, those with PH readings above 3.8, require higher sulfate levels for their long-term preservation whereas the opposite is also true. Accurate PH meter readings are therefore a necessity for determining the adjustments a winemaker needs to make.The Apera instrument is made in China but, unlike most outsourcing manufacturers today, Apera inspects every PH910 meter and issues a quality certificate showing its serial number and the date it passed.I was initially confused by the manual that came with my new meter. There are three instruments referenced in it: the pH 910, a PH-only meter, DEC910 which is a conductivity meter, and the PC 910, a combination pH and conductivity meter. I’m using the pH-only meter. While I couldn’t check out all the device’s functions since I was toward the end of my Nebbiolo wine-making project when it came in, I concentrated on getting a good pH meter reading. The manual has step-by-step instructions on how to do a 3-point calibration. Calibration is necessary before taking an actual reading. A plasticized card with these instructions was also included with the meter and is sufficient to serve as a reminder once you've been through calibration the first time. Everything needed to take a pH reading and calibrate the instrument is located in the box. Fortunately, the meter came with the LabSen 211 probe, the correct one needed for beer and wine analysis.After calibration, I tested the PH of my wine, The reading was 3.53, well within a red wine’s range of 3.2 to 3.8. Two decimal point accuracy like the reading I got wasn’t possible with my other pH meter. It's nice to have something so precise to work with.The instructions for setting up the electrode were pretty clear except for one thing. Mentioned in the instructions was a blue rubber plug that needed to be removed from the electrolyte breather hole on the probe. I initially tried to remove the electrode which was also blue thinking that might be the referenced plug. Nothing moved! Then I looked again at the little rubber band on the top of the electrode, one I initially thought was just there to secure the probe in the instrument base. Sure enough, it was plugged into a very small hole. Once I pulled the plug out, I was able to move on with the calibration routine. Oftentimes, it’s the simplest things that get me stumped.
