High-precision pH sensor - AMT/-PH300
Real-time monitoring of water pH starts with a high-precision pH sensor
Response speed reflects the real-time performance of the sensor. Conventional products have a response time within 180 seconds, while sensors using advanced technologies such as ISFET can shorten the response time to within 3 seconds.
Measurement range: pH: 0~14.00pH;
Accuracy: ±0.02pH;
Resolution: 0.01pH;
Stability: ≤0.02pH/24 hours;
Output signal: A: voltage signal (choose one from 0~2V, 0~5V, 0~10V)
B: 4~20mA (current loop)
C: RS485 (standard Modbus-RTU protocol, device default address: 01)
Product Introduction
Measurement range (span)
The measurement range of most pH water quality sensors is 0 to 14pH, covering the entire pH range. Some high-end industrial-grade products can extend the range to -4.00 to 18.00pH.
2. Measurement accuracy
Accuracy is the core indicator for measuring sensor quality. Products of different grades have different accuracy levels:
Industrial-grade digital sensor accuracy up to ±0.02pH
The accuracy of conventional online monitoring products is generally ±0.1pH
High-end models can achieve accuracy of ±0.01pH or even higher
Main Application Areas
- Water Treatment — Monitoring and controlling pH levels in municipal and industrial wastewater treatment processes to ensure compliance and efficiency.
- Aquaculture — Maintaining optimal pH in fish farming and aquaculture systems to promote healthy aquatic life and maximize yield.
- Chemical Processing — Ensuring precise pH control in chemical manufacturing and processing to maintain product quality and safety.
- Environmental Monitoring — Continuous monitoring of pH in natural water bodies, rivers, and lakes to assess environmental health and detect pollution.
