VIVOSUN AeroLab P30 Digital pH Meter | ±0.01 pH Accuracy, ATC & Replaceable Probe

Product Introduction

TheVIVOSUN AeroLab P30 Digital pH Meter is a high-accuracy portable water testing pen designed for growers, hydroponic systems, aquariums, irrigation setups and other applications where reliable pH monitoring is important. It measures across the complete0.00–14.00 pH range with a resolution of0.01 pH and published accuracy of±0.01 pH.

Built-inAutomatic Temperature Compensation (ATC) helps maintain reliable readings as water temperature changes, while the meter simultaneously provides temperature information across a0–50°C measurement range. This makes the P30 particularly useful when checking nutrient solutions, hydroponic reservoirs, DWC systems and irrigation water where both acidity and temperature can affect growing conditions.

The AeroLab P30 also combines one-touch calibration, automatic stability detection, Auto HOLD, an interchangeable probe and anIP67-rated body in a compact handheld design. A backlit LCD provides clear readings, while the replaceable electrode allows the sensing component to be changed when required instead of replacing the entire meter.

Digital Measurement & Calibration Control

TheVIVOSUN AeroLab P30 is designed to make regular pH testing straightforward while still providing the calibration functions required for accurate water management.

The meter supports1-point, 2-point and 3-point automatic calibration with intelligent buffer recognition and automatic stability checking. BothNIST and USA calibration standards are supported, allowing the meter to work with commonly used calibration solutions.

For NIST calibration, supported reference points arepH 4.01, 6.86 and 9.18. USA calibration mode supportspH 4.00, 7.00 and 10.01.

The display provides measurement stability information and allows readings to be locked using either manual HOLD or the configurableAuto HOLD function. An adjustable automatic shut-off timer can also be set between5 and 20 minutes to help conserve battery power.

Important: The AeroLab P30 is a standalone digital testing meter. It doesnot require Wi-Fi, the VIVOSUN App or a GrowHub controller.

The meter's menu also references future ORP probe support, but VIVOSUN's current manual states that an ORP probe isnot currently supported. The product should therefore be marketed primarily as a pH and temperature meter.

AeroLab P30 High-Accuracy pH Testing

TheVIVOSUN AeroLab P30 measures liquids from0.00 to 14.00 pH, covering acidic, neutral and alkaline solutions commonly encountered in indoor growing, hydroponics, aquariums and water management.

Its±0.01 pH accuracy and0.01 pH resolution make it suitable for applications where small changes in nutrient-solution pH need to be identified.

Automatic Temperature Compensation helps account for changes in solution temperature when producing pH readings. Temperature itself can be measured from0°C to 50°C, with a resolution of0.1°C and published temperature accuracy of±0.5°C.

The display incorporates measurement stability indicators so growers can identify when a reading has settled before recording the result. Auto HOLD can also be configured to lock a stable measurement automatically.

Portable Water & Nutrient Testing

The AeroLab P30 is designed as a portable testing instrument that can be used across a range of liquid-testing applications.

For indoor growers, it can be used to check the pH ofhydroponic nutrient solutions, DWC reservoirs, irrigation water and other liquid feeding systems. Regular pH measurement can help growers understand whether their nutrient solution remains within the range appropriate for their particular plants and growing method.

Outside indoor gardening, VIVOSUN also lists applications includingaquariums and laboratory water testing, making the meter useful wherever accurate liquid pH readings are required.

The slim pen-style body measures approximately191 mm long and weighs around120 g, allowing it to be carried and stored easily alongside other grow-room measuring equipment.

The meter is intended for measuring liquids, but VIVOSUN advises that the entire device shouldnot be fully submerged in water.

Replaceable Probe & IP67 Protection

A key feature of the AeroLab P30 is itsinterchangeable pH electrode.

Rather than requiring the complete meter to be replaced when the sensing probe eventually reaches the end of its useful service life, the electrode can be replaced separately. This provides a more practical approach to maintaining long-term measurement performance.

The meter carries anIP67 protection rating, providing resistance against water and dust during normal use. Its durable PC housing is designed for routine water-testing environments, while the sealed probe cap contains a moist sponge to help maintain proper electrode condition during storage.

The P30 should still be handled as a precision measuring instrument. The body should not be completely submerged, and the electrode should be rinsed and maintained according to VIVOSUN's instructions.

Automatic Temperature Compensation

Changes in water temperature can influence pH measurement, particularly when testing nutrient solutions and hydroponic reservoirs under varying environmental conditions.

The AeroLab P30 includesAutomatic Temperature Compensation, helping the meter provide stable pH measurements as solution temperature changes.
