• A VIVOSUN digital pH probe water tester meter with a cream-colored body, dark blue accents, and a green LCD screen, shown alongside its protective cap on a white background.
  • A digital pH level meter shown next to a vertical color chart labeled Acidic, Neutral, and Alkaline, with examples of substances that produce pH levels. The product is pictured partially submerged in a glass of water against a black background.
  • A handheld EC meter for DWC, NFT, aquaponics, and hydroponics is shown being used in a greenhouse setting with leafy plants. A human hand is visible touching the device, and text overlays describe the product's range, resolution, and accuracy.
  • A digital TDS water quality meter shown standing in a glass of water on a black background, with explanatory text and a color-coded scale on the left indicating TDS levels in PPM and drinking water recommendations.
  • A handheld salinity meter with a black and cream body is shown against an underwater coral reef scene, with a finger pressing the button. Text overlays describe salinity measurement, measuring range, and high accuracy electrode.
  • A 2x3 collage showing six real-world applications of a hydroponics and DWC plant growing system: a baby swimming in a pool, leafy greens in a hydroponic rack, a grow system in a kitchen, fish in an aquarium, a black DWC bucket, and hands washing a carrot under running tap water.
  • A 1-in-1 multi-function pH meter shown on a white background with labeled callouts and feature icons. The main product is a handheld digital meter with a cream body, dark blue cap, and green screen, alongside a separate protective cap and a close-up of the battery.

VIVOSUN 5-in-1 Digital pH TDS EC Salinity Temperature Meter Water Tester

Test water quality more easily with the VIVOSUN 5-in-1 Digital pH Meter, designed to measure pH, TDS, EC, salinity, and temperature with one compact testing device. Its multiple testing modes and wide measurement ranges make it useful for hydroponics, aquariums, household water testing, laboratory applications, and other liquid testing needs.

The pH meter measures from 0.00–14.00 pH, while the tester also provides TDS, EC, salinity, and temperature readings. Multiple functions can be switched with the push of a button for convenient everyday testing.

Featuring automatic three-point pH calibration, the meter can identify pH 4.00, pH 6.86, and pH 9.18 calibration solutions. The built-in automatic temperature compensation (ATC) helps account for temperature changes in the tested liquid for more stable readings.

A clear backlit display makes readings easier to see, while the wide measurement ranges and compact pen-style design make this a practical tool for home users, hydroponic growers, aquarium owners, and laboratory testing.
