Its slim, replaceable probe fits test tubes perfectly, while intelligent features like auto power-off and probe invalidation reminders keep your testing seamless.

## Description

The Apera Instruments SX620 pH Pen Tester is featured with a reliable pH/temp. measuring performance with a single-button operation in a slim body. An ideal choice for your regular liquid pH testing, including hydroponics, aquaculture, water treatment, pools& spas, educational purposes, beverage making, cooling towers, body fluid (saliva, urine), etc. The slim pH probe is suitable for test tube measuring, and is even replaceable such that you don't have to get rid of the whole meter when the probe is aged.Easy Auto Calibration (3 points: 4.00, 7.00, 10.01) and 0 to 60˚C Auto Temperature Compensation (ATC), ±0.01 pH accuracy with 0 to 14.0 pH measuring range. Intelligent functions: switch from ˚F to ˚C, automatic power-off, low battery alarm, pH probe invalidation reminder (remind you to replace the probe for better performance).The meter comes with a complete kit of premixed calibration solutions (4.00, 7.00, 10.01 – good for 10-15 times of calibrations), storage solution (3M KCL), CR2032 lithium batteries all in a portable carrying case. IP57 waterproof and dustproof. The meter is CE certified and comes with a 2-YEAR Warranty (6 months for the probe).

Review: 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: I've been using pH strips for my fermentation business. This is so much more precise and clean. Love it!
