VIVOSUN High Accuracy Digital pH Meter
The high accuracy pH meter for nutrient solutions and other water-testing applications, with a 0.00–14.00 pH range, ±0.01 pH accuracy and automatic temperature compensation.
About This Item
- High accuracy testing: Measure pH from 0.00 to 14.00 with the manufacturer’s stated ±0.01 pH accuracy and automatic temperature compensation.
- Flexible calibration: One-touch calibration supports one, two or three points, smart buffer recognition and an automatic stability check.
- Two buffer systems: Choose NIST 4.01/6.86/9.18 or USA 4.00/7.00/10.01 standards as supported by the manufacturer.
- Replaceable electrode: The interchangeable probe design allows electrode replacement rather than replacement of the entire meter.
- Durable construction: IP67-rated PC housing and a sealed cap with a moist sponge help protect the meter and maintain electrode condition.
- Convenient readings: A backlit LCD, automatic and manual hold, and adjustable automatic shut-off support routine testing.
