Bút Thử Chất Lượng Nước Tds / Ph 3 Trong 1

-tri-one water quality test: the ph meter has three-in-one function and can measure ph, tds and temperature with high accuracy.All-round measurement of water quality to ensure the health of water quality.
-high accuracy: tds instruments for examining the contents of tds/salt (nacl) in light houses, ponds and water purification systems.The tester has a sensitive electrode sensor and can read accurate ph values.The attached detailed manual will show you how to get the best accurate and stable readings.
-automatic calibration: tds/ph testers have automatic temperature compensation functions, can be adjusted to water temperature and quality, and can obtain ph readings almost immediately.Similarly, you can use buffer powder to calibrate the tester through a key button.
-automatic temperature compensation: the ph meter has built-in (atc) automatic temperature compensation function, so it can accurately determine the ph of the sample at any temperature within 0 range, and therefore no longer needs to accommodate the temperature of the test liquid. °C-60°C (32°F-140°F).
-widely used: pocket tds ph meter is an ideal test kit for home and laboratory use.Test ideal options for water, swimming pool, aquarium, spa center, hydroponics, food, wine and beer.
