DS4-PH3-2000 Intelligent Electrochemical Phosphine Gas Sensor
1. Product Overview:
The DS4-PH3 is a high-performance gas sensor specifically designed to detect phosphine (PH₃) gas concentrations. Utilizing advanced electrochemical sensing technology, it delivers high sensitivity, rapid response, and excellent selectivity, making it ideal for grain storage, agricultural greenhouses, and industrial gas monitoring applications. It enables precise detection of low-concentration phosphine gas to ensure environmental and operational safety.
2. Key Features:
3. Working Principle:
The DS4-PH3 employs a three-electrode electrochemical cell, comprising:
The current magnitude is directly proportional to the phosphine concentration, enabling precise quantification.
| Detection Range | 0–10 ppm (customizable) | Adjustable range (e.g., 0–50 ppm) based on requirements. |
| Resolution | ≤ 0.05 ppm | Minimum detectable concentration change; reflects sensor precision. |
| Operating Temperature | -10°C to 50°C | Performance may degrade outside this range. |
| Operating Humidity | 10% to 90% RH (non-condensing) | High humidity requires anti-condensation measures. |
| Output Signal | 0.1–3V (analog) or UART/I²C (digital) | Analog: direct ADC input; Digital: protocol customizable (e.g., 9600bps baud rate). |
| Power Supply | 3.3V or 5V DC | Compatible with most embedded systems (e.g., Arduino, Raspberry Pi, industrial controllers). |
