Model: FD-SENSOR-SERVICEAvailability: Usually in stock Features ⚛️ Using high-precision Nano-Gas-Electrochemical Sensors 🚄 Fast turnaround time, about 72 hours once received. 🔬Includes calibration after the sensor has been replaced. 💪 Using NIST-traceable reference gas. Select from the following sensors: Oxygen (O2) electrochemical Carbon Monoxide (O2) electrochemical Hydrogen Sulfide (H2S) electrochemical Ammonia (NH3) electrochemical Hydrogen (H2) electrochemical Description This is our full-service Gas Detector Sensor Replacement & Calibration Service. Over time, gas sensors degrade, leading to inaccurate readings or complete failure of your gas detector. After purchasing this service, simply ship your unit to us at your expense, and our technical experts will handle the rest. We will replace your degraded sensor. Following installation, we perform a precise calibration using NIST-traceable reference gas, guaranteeing your device adheres to national standards. We will then send it back with a signed and dated certificate. Your instrument is serviced and shipped 72 hours after we receive it - and return shipping costs are included (for USA and Europe/UK only). Instructions Purchase the service.
