## Description

Aprea Instruments SX610 pH Pen Tester is designed for reliable measuring performance with a single-button easy operation in a mini body. A cost-effective choice for your general-purpose pH testing, including hydroponics, aquaculture, water treatment, pools & spas, beverage making, education, etc. The 8mm slim pH probe is replaceable and suitable for test tube measuring. Easy 1-3 point Auto. Calibration (7. 00, 4. 00, 10. 01) and 0 to 60˚C Auto. Temperature Compensation (ATC), 0. 01 pH/0. 6˚C accuracy with 0 to 14. 00 pH measuring range. Intelligent functions: switch from ˚F to ˚C, automatic power-off, low battery alarm, pH probe invalidation reminder (reminds you to replace the probe for reliable performance). The meter comes with a complete kit of premixed calibration solutions (7. 00, 4. 00, 10. 01), storage solution (3M KCL), CR2032 lithium batteries all in a small pocket carrying case. IP57 waterproof and dustproof floats on water, so you don’t have to worry if it falls in water by accident. The product is CE and RoHS certified, and is manufactured under an ISO 9001: 2015 certified quality system. Do NOT store the probe in distilled water or deionized water since it will cause damage to the electrode. Only use distilled water for rinsing the pH probe.

Review: Excellent instrument - Easy to use, appears to be accurate and truly beats the cheap $10-30 meters that are unstable and can take minutes to indicate a fixed reading. This instrument gives a presumably accurate result almost immediately. Supplied calibrating solutions are sparse but can evidently be reused if the probe is carefully cleaned as directed. A single multi-function button that works well replaces the two or three often present on other models. Allegedly waterproof, and the probe is replaceable. Sealing probe cap holds supplied soaking solution to protect and prolong life of electrode. Extra batteries supplied are a plus. Good instructions and warranty. Factory calibrated and even has its own serial number. Not a professional device that can cost hundreds, but certainly worth its price.
Review: Garbage, don't waste your money - At first, I thought this was a good product. It seemed to calibrate easily. It worked for about 2 years and then it didn't . It acted like the batteries were dead, it would turn on and then turn itself off like the batteries were low. I took the batteries out and tested them and they were nearly perfect. I put them back in, same issue. I switched to new batteries same thing. Then it finally started turning on and the ph counter was swinging all around up and down like crazy before maxing out at 15. Turning it on and off many times it did more inconsistent crap. Then I thought it was working again so I tried to calibrate it with ph 4 solution. It registered it as 10 ph and calibrated to that. Tried the 7 ph solution it calibrated to 10 again. I contacted support and they told me I needed a new probe. I check the price on their website $48 plus shipping for a new probe $55 on desertcart. So a new meter is $69 and a replacement probe is $55? Get real and I don't even know if the probe is the problem. I started reading comments on the replacement probe and many were stating they had the same exact weird problem I had. They had bought the probe in hopes of fixing their meter only to find out that it was the electronics, not the probe. Then when they contact support they are told it is their fault, they must have gotten the meter wet. I'm now not sure how accurate this meter is because I have no way to test it anymore and it didn't occur to me in the past it could have been off. But looking back now it did seem to almost always give similar results when testing soil ph. I'll be going back to the cheapo Ph meters until I can get the money to buy a really nice one that is not made in China. I could have bought 7 cheap ph meters for the price of this junk. I thought I would try moving up to a better meter. I should have spent a little more at the time to get something of true quality. The cheap ones work as well as this one, but this had the fancy skinny probe to fit in test tubes so I could use smaller sample sizes. It just sucks this wasn't the quality product I was hoping for. Avoid this Junk meter. If replacing the probe worked I'd try it, but I don't want to spend $55 just to have to turn around and send it back. This thing is acting like it is an electrical issue, not a probe.
