How To Remove Dissolved Oxygen From Water

Four common techniques can be used to remove dissolved oxygen (DO) from water, both chemically and mechanically. These techniques include boiling water at 1 atm (atmospheric pressure), boiling water under reduced pressure, nitrogen (N) purging, and sonication under reduced pressure.  Dissolved oxygen (DO) is the amount of oxygen present in water. We can easily measure

Why You Should Use A CO2 Scrubber For Your Aquarium

CO2 scrubbers are used in both freshwater and saltwater aquariums that contain a protein skimmer to help control pH levels. So, if you have issues with elevated pH levels in your saltwater (or freshwater) aquarium, using a CO2 scrubber will help you maintain healthy levels. Are you struggling to maintain a pH range in your

How Do CO2 Scrubbers Work?

A CO2 scrubber is essential for removing CO2 from the air. Air polluted with CO2 is pumped into the scrubber, which reaches an ion exchange resin that isolates the CO2 molecule from other gases. The polluted air is then cleaned and pumped out of the CO2 scrubber, which then must either be discarded or reused.

How Does An NDIR CO2 Sensor Work?

NDIR CO2 sensors detect and monitor CO2 in the air based on the absorption of infrared (IR) light at a given wavelength. An IR lamp directs light waves through a tube towards a filter. The amount of IR light that passes the filter is measured by an IR light detector.  Carbon dioxide (CO2) is an

Proper CO2 Sensor Location – Where To Mount Your NDIR Sensor

Where to permanently mount your non-dispersive infrared (NDIR) sensor depends on why and where you are monitoring CO2 levels indoors, however, for best results they are usually placed 4-6 feet from the floor, also known as the “breathing zone”. Carbon dioxide (CO2) is an inert gas, formed from respiration, combustion, and organic decomposition. As it

How Do Humidity Sensors & Probes Work?

Humidity probes detect changes that alter the temperature or electrical currents in the air. There are three main types of sensors: capacitive, resistive, and thermal conductivity depending on what industry or application you will be measuring.  Humidity is how much water air contains. The presence of water in the air can affect human health and

How Does Conductivity Affect Water Quality?

Conductivity is a vital parameter when determining water quality. As salinity and temperature increase, conductivity also increases, which can have a negative effect on the quality of water. This is because the higher the conductivity, the higher amount of impurities (dissolved substances, chemicals, and minerals) are in the water. Conductivity is one of the most

How Do Conductivity Meters Work?

A conductivity meter is an essential measuring tool for a range of applications and industries. When the probe (attached to the conductivity meter) is inserted into the solution, an electrical current flows between the electrons inside the probe which reads the electrical current, providing a conductance value.  Electrical Conductivity or (EC) measures the ability of

Does Temperature Affect Conductivity?

Temperature affects the conductivity of solutions and metals, because of the effect it has on the viscosity of solutions and the nature of ions. When temperature changes, so does conductivity; conductivity invariability increases when temperature increases. Electrical conductivity (EC) measures the ability of a material to transmit an electrical current over a certain distance, commonly

How to Build a DIY CO2 Meter with Arduino

In this tutorial, we will show you how to make a benchtop-style CO2 meter using our EZO-CO2™ Embedded Carbon Dioxide Sensor connected to an Arduino Uno. The real-time readings will be shown on a liquid crystal display (LCD) in PPM. Both the sensor and display are connected to the Arduino via I2C. Note This device
