When I tried this product, I was impressed with its accuracy and portable design. The Extech DO700 is perfect for any professional or hobbyist looking to analyze dissolved oxygen in water samples for industrial and scientific purposes. The LCD display is clear and easy to read, and the automatic temperature compensation function ensures precise measurements. The only downside I found is the price, but it's worth the investment for the convenience and accuracy it offers.
