IGD 750S Sampling NH3 Gas Detector

The TOC-750S NH3 provides near-continuous gas monitoring for Ammonia in a sampling format, allowing for remote detection of ammonia gas. This detector is ideal for detection in difficult to access or harsh areas such as valve stations and freezer rooms. It is also ideal for detection directly into freezers and chillers without needing a detector directly in the area, as the 750S can provide detection for up to 20m away.

IGD 750S Sampling NH3 Gas Detector is an addressable aspirated gas detector which allows you to provide gas detection in areas otherwise difficult to access or harsh to normal diffusion sensors. Featuring our unique piezo pump technology, our aspirated gas detectors have virtually no moving parts and virtually silent in operation. Thus, reducing maintenance requirement and providing near continuous gas detection up to 20M away.

The TOC-750S uses IGDs Sentinel+ 2-Wire addressable technology, for fast, secure and digital communication across as much as a 1km distance between detectors. This system also offers continuous monitoring with the ability to easily check your system status from your phone with our IOT capabilities. Additionally, this IOT capability allows for easy system set up straight from your phone.

IGD’s Ammonia systems can be fitted with its latest ionic ammonia gas sensors. These sensors offer effective detection in temperatures as low as -40°C and harsh environments. Sensor ranges are available up to 5000ppm. This new line of sensors resolves the issues of short life spans and low maximum range of the existing consumable Ammonia sensors in the market, making them perfect for the refrigeration industry.
