We are pleased to announce that we have expanded our product portfolio to include Honeywell’s industry-leading gas sensors. With nearly 50 years of innovation in gas sensing technology, Honeywell offers one of the broadest and most advanced sensor lineups on the market today.
What’s New in Our Offering?
We now carry a wide range of Honeywell’s gas sensing solutions for various applications—from industrial safety to environmental monitoring, agriculture and more. The gas portfolio includes 44 different gas types, here’s a quick look at the key series now available:
iSeries (Digital Gas Sensors)
Compact, intelligent “plug & play” sensors with a 5-year lifespan. Ideal for industrial safety, water treatment, and area/personal protection.
Long-Life Ammonia Sensor
Engineered for continuous ammonia exposure in agriculture and hydrogen economy applications. Offers over 12 months of stable performance.
1, 4, 5 & 7 Series
From compact and low-profile sensors to robust, high-performance devices, these series cover carbon monoxide, oxygen, hydrogen sulfide, sulfur dioxide, nitric oxide and more.
AQ7 Series – Environmental Air Quality Sensors
High-resolution sensors for CO, NO₂, SO₂, and O₃, designed for urban air quality monitoring, UAVs, and environmental assessments.
CRIR Series – CO₂ Sensors
NDIR-based sensors optimized for HVAC, indoor air quality, and smart systems, with maintenance-free performance and automatic baseline correction.
Carbon Monoxide Sensing (Ecosure & Ecosure x)
Designed for unattended operation and log life: Ecosure = >6 years in normal use, Ecosure X >10 years in normal use
Medical Gas Sensors – iSeries M, MNO2, MND2
Reliable and accurate O₂, NO, and NO₂ sensors for life-saving medical devices, with cost-saving predictive calibration and extended service life.
