                                          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​​:

  • ​​Target Gas​​: Phosphine (PH₃), optimized for agricultural fumigation and industrial gas leak detection.
  • ​​Detection Principle​​: ​​Electrochemical sensing​​. Phosphine undergoes redox reactions on the sensor’s electrode surface, generating a current signal proportional to its concentration—combining high accuracy with anti-interference capabilities.
  • ​​Measurement Range​​: ​​0–10 ppm​​ (standard); customizable up to ​​0–50 ppm​​ or higher (specify model).
  • ​​Sensitivity​​: Detects phosphine concentrations as low as ​​0.05 ppm​​ (exact value subject to factory testing).
  • ​​Response Time (T90)​​: ≤ ​​45 seconds​​ (time from gas exposure to stable output).
  • ​​Recovery Time​​: ≤ ​​90 seconds​​ (time to return to baseline after gas removal).
  • ​​Operating Temperature​​: -10°C to 50°C (high temperatures may affect sensitivity; standard range recommended).
  • ​​Operating Humidity​​: 10% to 90% RH (non-condensing); high humidity requires moisture protection.
  • ​​Output Signal​​: Supports ​​analog voltage (0.1–3V)​​ or ​​digital communication (UART/I²C)​​, compatible with PLCs, microcontrollers, and data loggers.
  • ​​Power Supply​​: 3.3V DC or 5V DC (typical power consumption ≤ 50mW, low-power design).
  • ​​Lifespan​​: 2–3 years (actual lifespan affected by gas exposure; regular calibration/replacement required).
  • ​​Protection Rating​​: IP54 (dust/water resistance, standard) or IP65 (custom explosion-proof, for harsh environments).

3. Working Principle​​:

The DS4-PH3 employs a ​​three-electrode electrochemical cell​​, comprising:

  • ​​Working Electrode (WE)​​: Phosphine diffuses through a permeable membrane and undergoes oxidation, releasing electrons to generate a current.
  • ​​Counter Electrode (CE)​​: Completes the redox reaction to maintain circuit balance.
  • ​​Reference Electrode (RE)​​: Provides a stable potential reference for consistent signals.

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).
