The Gas Analyzer allows the measurement of respiratory gas concentrations from tiny insects through to humans.

Qubit Systems provides numerous environmental sensors and probes for monitoring of environmental parameters such as temperature, pH, salinity, soil moisture, relative humidity, dissolved O2 and CO2, plus light quality and quantity. We provide gas analyzers for monitoring O2, CO2, H2, CH4 levels in the field and in environmental chambers..

Qubit Systems provides various ranges of gas flow meters from simple rotameters that can monitor flows from 2ml/min to 10L/min, to mass flow monitors used with data collection software.

Gas mixing systems made by Qubit are customized system with up to 9 different mass flow controllers that can blend gases from ml to few hundred Litres. Gas mixtures are set in software and can be supplied to multiple sources with high accuracy.

Qubit Systems provides gas pumps to fit your application. Our gas pumps are integral part of any gas exchange or gas control systems. High accuracy, low and high flow gas pumps are available. We can provide customized gas pumps for any application. Contact us with your specifications.

Qubit offers various systems for gas control. From control of gas concentration in a chamber to control of gas flow through a multichannel gas measuring system, we provide customized setups to meet user's applications. In control of specific gas concentration we employ a solenoid gas controller (A365) which controls the release of a minor gas in the background of a major gas.

Columbus Instruments, Model 180C Gas Analyzer is a modular system that allows for multiple gas and/or multiple sample configurations.

The CapStar-100 Carbon Dioxide Analyzer provides continuous measurement of expired CO2 over the range 0-10 percent. Its rapid response time, small sample flow requirements, and long-term stability make it ideal for respiratory gas measurement of rodents and larger animals.

The microCapStar End-Tidal Carbon Dioxide Analyzer provides accurate end-tidal or continuous measurement of expired CO2 in animals as small as mice. It features very low sample flow requirements, rapid response time, and long-term stability. Respiratory rate (RR) is computed using the excursions of the CO2 waveform.

The GEMINI Respiration Monitor measures CO2, O2, and respiration rate of spontaneously breathing or ventilated animals. It provides breath-by-breath readings for end-tidal CO2 and O2, and instantaneous respiratory rate (breaths/minute). Adjustable alarms are provided to monitor CO2 and respiratory rate.

The digitalPID (digital Photo-Ionization Detector) sensor is used to record concentration fluctuations of the dispersing gas as it passes by the sensor location.

The 200B miniPID photo-ionization detector combines small size, fast response, and high sensitivity in an easy-to-use, competitively priced package.

Oxymax-C is a special adaptation of the Columbus Instruments Oxymax Deluxe System with features specific to compost research.

A highly adaptable general purpose closed circuit respirometer with very high sensitivity.

Our new Portable Gas Meter is an inexpensive, battery-operated gas analyzer.

The OxyStar-100 is a fast-response, high accuracy oxygen analyzer for respiratory monitoring, hypoxic gas studies, or general laboratory use.

Oxygen consumption system for 1 - 16 animals.
