HITECH INSTRUMENTS A member of the MTL Instruments Group technical datasheet Z230 oxygen analysers Zirconia sensor analysers for oxygen • Proven technology from gas analyser experts • Fast response, integral sensor • ppm to % O2 levels • Non-depleting, long life sensor • Choice of sample systems Applications • Nitrogen generators • Inert gas systems • Air separation • Soldering systems • Reflow ovens • Packaging • Gloveboxes The Z series of oxygen analysers feature sensors based on zirconium oxide technology. They have the advantages of fast response times, excellent accuracy at ppm levels and a non-depleting sensor for long life. A range of different configurations and internal sample systems are available – so we can find the product that is right for you. Choose the Z230 for versatility and portability. This benchtop analyser is a fully self contained, complete unit with integral sensor and pump (optional). The carrying handle makes it easily transportable and the integral flowmeter and valve mean there are no further accessories or consumables to carry around. The analyser features bi-directional RS232 allowing remote calibration and datalogging. There is a choice of outputs and both outputs and alarms are user programmable. The internal pump option is chosen if there is insufficient flow in the sample stream and, for applications where a long sample path is involved, a bypass flow sample system enables faster results. Not all zirconia sensors are the same. Hitech Instruments manufacture zirconia sensors in-house. Careful choice of raw materials and Hitech’s manufacturing ‘know how’ result in a fast responding, robust sensor with excellent specification and a very fast warm-up time. Different sample systems are available for applications involving long sample paths and high pressure. Bespoke designs are also available according to the application. Oxygen is measured in a wide variety of processes to confirm the presence or the absence of it. The most common application is to measure oxygen as the impurity in other gases, e.g. nitrogen generators. Oxygen is required in aerobic processes and situations that require user intervention, e.g. to ensure that it is safe to enter a chamber for maintenance work. Some processes require the absence of oxygen to be efficient, e.g. furnace atmospheres, others just require a low level of oxygen for safety reasons, e.g. inert gas blanketing. Hitech offer a number of different solutions for oxygen measurement dependent on the application. Our technical sales engineers will be pleased to advise the system that is right for you. The Z series from Hitech Instruments – the last word in fast, ppm oxygen measurement.
