K-33 ICB 10% CO2 Sensor

The K-33 ICB 30% CO2 Sensor model SE-0026 by SenseAir is designed to measure up to 30% CO2 by volume. It is useful for biological or scientific applications where artificially high levels of CO2 must be maintained in an enclosed apparatus. However, some of our clients who purchased the 30% sensor were looking for a balance between measuring higher levels of CO2 and accuracy. That’s why we’ve just introduced the K-33 ICB 10% (100,000ppm) CO2 sensor model SE-0025 and CM-0058 Sensor Development Kit.   The K33 ICB 10% CO2 sensor is also a tube-in/tube-out sampling sensor. It has the same...

Check Your Filters

  Just like the furnace filter in your house, many CO2 meters have filters to keep out liquids and dirt. And just like the furnace filter in your house, the filters in your CO2 meters need to be changed when they get dirty too. Sampling Devices CO2Meter’s Sampling Data Loggers and sensor devkits with micro-pumps have inline water, moisture and dust filters designed to allow air flow in while keeping out moisture, dirt, dust or mold spores that can affect the sensors. If you are using your meter or sensor in a clean environment, these filters should be checked every 6 months....

Portable CO2 Meter Developed for Chilean Market

RYF Technologies recently showed us a prototype for a new portable CO2 + RH/T meter created using our carbon dioxide sensor. It is designed for the Chilean market. The meter is currently being tested using a COZIR Wide-range sensor with low power requirements especially suited for battery-powered devices. In addition to the sensor, the prototype shown uses a tube cap kit and micro-pump for sample gas drawing, and an Arduino micro-circuit board to display the results in real-time on an LCD screen. A particularly interesting feature is that CO2 sensor's output is combined in source code with data from a...

CO2 Important for Ripening Fresh Produce

Did you ever wonder how produce at the grocery store is always at the peak of its ripeness on the shelf? Chances are, carbon dioxide was involved. Some produce like apples have their ripeness retarded by storing them in CO2. Large storage containers are lined with heavy bags and filled with young apples. The bags are sealed, then pumped full of CO2 gas. Stored in this manner, some produce can remain in an unripened state for weeks after picking. A leak in a storage bag can represent hundreds of pounds of produce lost. To test for leaks, shippers use our...

CO2 Used to Roast, Decafeinate Coffee

If you enjoy a good cup of coffee, you may have CO2 to thank for it. Coffee beans are typically roasted in hot air. One of the most critical aspects of roasting is that the air temperature needs to be high enough to cause the green beans to change color, taste and smell, but not to burn them. To accomplish this, some coffee roasters add CO2 to the hot air to control the intensity of the heat verses the moisture content to prevent the coffee from being “singed.” This would result in a burnt taste when the coffee is brewed....
