Ammonia Gas Sensor with 3G Connectivity SIAQ-3G-NH3

SKU: SIAQ-3G-NH3

Doc No: SIAQ-3G-NH3-DS-EN-10

Introduction

SIAQ-3G-NH3 is an electrochemical-type gas sensor which has high sensitivity to low concentrations of ammonia gas, high selectivity, and a stable baseline. With modular design, it allows user to replace the measurement module easily when the sensor life reached the limit. The device has built-in IoT gateway with 3G cellular connectivity allow to connect easily to any IoT platform. The measurement sensor is from Japan to deliver the highest performance and accuracy.
