This Quarter: Interlink Electronics Announces New Sensor Solutions for Wildfire Outdoor Air Quality (OAQ) Monitoring, Formaldehyde Sensing, and much more!

Formaldehyde (HCHO) is a trace organic gas common in indoor environments, usually emanating from many common sources including building materials, paint, insulation, flooring, glues, some types of fabric (ex. furniture), etc.

What makes formaldehyde critical to monitor is that it is a known cancer-causing agent. The International Agency for Research on Cancer (IARC), which is part of the World Health Organization (WHO), has concluded that “formaldehyde is carcinogenic to humans.” It has been determined that exposure to even low levels of formaldehyde causes other undesirable health affects as well, like nausea, wheezing, burning sensation in eyes, nose, throat, skin, etc.

In addition to residential settings, formaldehyde is also to be found in some industrial operations. The US Occupational Safety and Health Administration (OSHA) has determined that occupants in offices or homes should be exposed to no higher than 0.75 ppm of formaldehyde on average over an 8-hour workday.

Interlink Electronics is pleased to announce a complement to its existing 110-85x family – the 110-86x family offers improved sensitivity while continuing to offer high stability, as well as an accurate and linear response. Like all of Interlink’s electrochemical gas sensors, the 110-86x family is also distinguished by low power consumption, small size, low profile, easy-to-integrate packages, etc. The sensor family will be available in three different packages for ease of integration – pinned configuration, thick castellation and thin castellation packages, as shown in the pictograph below.

Interlink Electronics’ Screen Printed Electrochemical sensor (SPEC Sensor™) revolutionize the current state of the art in gas sensing by offering the performance of the best quality chemical sensors with compelling size, power, cost and ease-of-use advantages. IE’s sensors are ideal for health, food, environmental, industrial, and residential monitoring applications. Learn more about Interlink’s rich portfolio of more than a dozen electrochemical gas sensor families by visiting spec-sensors.com.

Sneak-peek: Interlink’s Upcoming Outdoor Air Quality Sensor Module

As part of our work on the previously awarded NOAA (National Oceanic and Atmospheric Administration) SBIR grant, Interlink Electronics is pleased to share its successful 2-prong development output:

(1) An integrated 4-gas module, featuring electrochemical sensors by Interlink Electronics. Optimized for detection of outdoor air quality as impacted by wildfires, this module includes high-sensitivity CO and three other gas sensors that impact air quality in this context. The design itself is quite modular, and can use any combination of our electrochemical sensors, thus offering the unique feature of optimal use in a number of applications that require multi-gas sensing, such as agriculture and food processing, health and wellness applications, and industrial safety applications.

(2) A deployed Outdoor Air Quality (OAQ) instrument, featuring: the integrated 

4-gas module with high-sensitivity CO and three other electrochemical gas sensors, a PM2.5 particle sensor, temperature, pressure, and relative humidity (TPRH) sensors, solar-rechargeable battery power, LoRa communication, and cloud-based data storage, analytics, and dashboard.

LAST TIME BUY OF Eco Sensors’ SM-7/SM-EC Ozone Sensor

Announcing Equivalent and Upgraded SM-500/RME New Ozone Sensor Module

Ozone, a natural substance, is employed in innovative ways in many application areas as an environmentally and economically sustainable solution. Interlink serves this market with a broad range of industry-best monitoring and control products and accessories. 

Due to factors beyond our control, Interlink Electronics has decided to end-of-life the SM-7/SM-EC ozone sensor products by March of 2025, and is pleased to offer a last-time buy opportunity to our customer base. 

PLEASE CONTACT INTERLINK’S SALES TEAM FOR VOLUME PRICING DETAILS ON THE LAST TIME BUY OF THE SM-7/SM-EC.

We are pleased to announce the SM-500/RME, an upgraded device in a smaller and more efficient footprint that meets or outperforms SM-7/SM-EC on all metrics. The new device can be seamlessly integrated into the OS-4 and OS-6 Ozone controllers. The SM-500/RME is a fully calibrated Ozone sensing instrument that utilizes a state-of-the-art electrochemical (EC) sensing element. It incorporates several key features that make it particularly useful for applications such as commercial laundry, odor remediation, commercial food preservation and storage, and water treatment. Key features of the SM-500 include:

• Integrates seamlessly with Eco Sensors’ OS-4 and OS-6 Ozone Controllers
• Includes a user-replaceable calibrated sensor module (RME) that enables users to easily maintain calibration requirements
• Integrated zero button for re-zeroing the sensor module in the application
• Available with standard calibration ranges of 0-20 ppm and 1-50 ppm
• USB micro-b port for optional power and serial communication
• Convenient data configurations: RS-232 transmission and 0-2V buffered analog output
• Temperature and relative humidity sensor data included in the digital output
