Gravity’s Innovative pH Monitoring Solution
Analog pH Sensor –A meter kit from Gravity has been developed to provide a precise yet cheap way of measuring pH in different environments and for different uses. Because of its simplicity of use and versatility that results from serving multiple functions indicated above, it is of great value to all users, particularly those dealing with water such as aquaculture farmers, hydroponic farmers, and water testers.
An Overview of the Gravity pH Sensor Kit
Calibration against the included buffer solution ensures reliable readings, typically maintaining an accuracy of ±0.1 to ±0.2 pH units depending on usage. Its largest component is an analog pH sensor probe head with a BNC interface, connected to the enclosed portable pH meter. This waterproof meter gives out pH readings on a large-size LCD that can be easily read out to the second decimal of pH.
Beyond just reading pH levels, the meter indicates if the reading is too acidic or alkaline via indicator lights. This provides at-a-glance status without needing to interpret numerical values. The meter is powered by three standard AAA batteries, providing approximately 1500 hours of use without requiring wall power or charging.
Along with the probe and meter, the kit also contains a bottle of pH 4 calibration solution for accurately calibrating the sensor. Detailed instructions walk users through the simple one-point calibration process. The probe is designed for submersion in liquid samples and features a durable epoxy body construction for long-term use in a variety of environments.
Overall, the Gravity pH Sensor Kit offers a complete monitoring solution in a portable, cost-effective package. Its analog design requires no software, WiFi, or other complicated setup – simply submerge the probe, power on the meter, and read pH values instantly. This makes it an ideal choice for basic pH testing needs.
