PS4-NH3-100

PS4-NH3-100 is a PS1 series Ammonia electrochemical gas sensor using a revolutionary ‘Solid Polymer Electrolyte’ technology that is based on the principle of catalytic reaction. The target gas to be measured generates a very small current, proportional to the gas concentration. The technology offers a stable, high-quality and cost-effective manufacturing process. Key applications include coal mine, general gas detection, industry, plating, and storage room.

• Small size, high sensitivity, wide temperature range
• Fast response time, no electrolyte leakage
• Low cost at large volumes, strong signal to noise
• Individually calibrated (including test report)
• 20 ±10nA / ppm sensitivity, measurement range from 0 to 100ppm, ±2nA zero current
• 20ppm maximum overload, T50 < 10s, T90 < 300s response time, 100 ohm recommended load resistor
• 1% repeatability, 100ppm linear range, 0.01ppm resolution (16Bit ADC), less than 5min warm up time
• Operating humidity range from 10 to 95% RH, pressure range from 800 to 1200hPa
• Less than 1%/month long-term drift, greater than 3 years in air expected lifetime, 12 month warranty
• PPO housing material, temperature range from -40°C to +55°C

Notes

Do not solder to the connector pins as this may damage the sensor and thereby invalidate the warranty.
