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.

High selectivity to NH3;
Small influence by H2S;
Excellent Durability to NH3 exposure;
Sensor life > 2 years;
Stable base-line;
3G Connectivity;
Ready to connect to Globiots platform;
Plug & Play.

Typical Applications

Monitor leakage of Ammonia gas for Refrigerator;
NH3 Monitoring;
NH3 Detector.
