Precision gas mixing device from HiTec
Zang
The HiTec Zang gas mixing device was especially developed for R+D applications which demand the best possible accuracy and reproducibility
The apparatus is available in six different configurations The number of mixing gases varies from one to four gases

Most powerful thermostat gains bigger range
The original Ministat claimed to be the most powerful thermostat in the world, weight for weight, and thousands of them have been sold around the world

New design is said to dramatically improve levels of performance and control: "it out performs systems almost twice its power rating" says UK distributor
Drawn either from the laboratory mains gas supply or from gas bottles with gas regulators.
The number of outlets varies from one to four.
All gas inlets can be fed optionally with the gases air, N2, O2 and CO2 and have a factory-made calibration for these gases.
Calibration for other gases is possible on request.
For each outlet a gas mix of up to four gases can be set up individually.
The physical units of the gas flow can be preselected on sccm (standard cm3/min) or g/min.
The parameterisation of the mixing values can be done optionally in percent or absolute values (e.g outlet 1 and 2 in %, outlet 3 and 4 in sccm).
At the percent input mode the total gas flow and the percent values are fed for the first three gases.
The remaining value is calculated automatically thus the sum will be 100%.
The actual concentrations are kept constant with high accuracy mass flow.
Advantages:.
Recording of value and event history.
Compact design.
Extensive control and protective devices.
Available for stand-alone operation and as Ramos upgrade application.
Control/protective devices.
Both inlet pressures and outlet pressures are measured and controlled for safety reasons.
If the allowable inlet or outlet pressure is exceeded the gas supply will be locked and an alarm signal will be activated.
If a pressure deficit is detected (deficient pressure difference) an alarm signal occurs.
Operation with Ramos.
At operation with Ramos the interface of the gas mixing device is integrated in the Ramos software.
The set values are specified by the operator.
The adjusted set values are logged in the operation report.
The measured flow rates are indicated numerically and the time course is displayed graphically.
Ramos is a fully automatic respiration activity monitoring system available from HiTec Zang and Labtex . Request a free brochure from Labtex ...
