아날로그 pH 센서/미터 키트 V2
(Gravity: Analog pH Sensor/Meter Kit V2)
개요
- 본 제품은 pH 센서 키트입니다.
- pH 값을 측정하여 산도나 알카리성을 측정할 수 있습니다.
- V1에 비해 좀더 개선된 정확도를 가지고 있으며, 모듈은 3.3-5V의 동작전압을 지원합니다.
- 하드웨어 필터된 출력 신호는 낮은 지터를 가지고 있으며, 소프트웨어 라이브러리는 two point calibration method를 지원하고, 자동으로 두개의 표준 버퍼 솔루션(4.0 및 7.0)을 구별할 수 있습니다.
- 아두이노를 이용하여 쉽게 pH 센서를 측정할 수 있게 하여 주는 제품입니다.
특징
- 3.3~5.5V wide voltage input
- Hardware filtered output signal, low jitter
- Gravity connector and BNC connector, plug and play, no welding
- Software library supports two-point calibration, and automatically identifies standard buffer solution
- Uniform size and connector, convenient for the design of mechanical structures
- Attention：
1. The BNC connector and the signal conversion board must be kept dry and clean, otherwise, it will affect the input impedance, resulting in an inaccurate measurement. If it is damp, it needs to be dried.
2. The signal conversion board cannot be directly placed on a wet or semiconductor surface, otherwise, it will affect the input impedance, resulting in the inaccurate measurement. It is recommended to use the nylon pillar to fix the signal conversion board, allow a certain distance between the signal conversion board and the surface.
3. The sensitive glass bubble in the head of the pH probe should avoid touching with the hard material. Any damage or scratches will cause the electrode to fail.
4. After completing the measurement, disconnect the pH probe from the signal conversion board. The pH probe should not be connected to the signal conversion board without the power supply for a long time.SPECIFICATION
