Z4010 portable oxygen analyser Features N Measures from 100% to less than 1ppm N Fast response time of less than 5s for 90% change N Fully autoranging N Fully programmable analogue output Two alarms channels, user-config- analyser measures a wide range of urable for high, low or off states and oxygen concentrations from percentage hysteresis, each provide one set of volt- levels to less than ppm in clean non- free changeover contacts. They can be reactive gas mixtures. Its robust carry- ing case, fast warm up time and switch- span of the instrument. A choice of two able supply voltage provide an ideal analogue outputs is available, 0 to 5V solution for on-the-spot oxygen monitor- or 4 to 20mA, each with several pre-set ranges. Sample flow adjustment and monitoring are built-in, along with a A large multi-digit, autoranging sample pump for applications with a LCD is used to display measured con- centrations and also user-adjustable parameters for alarm and analogue out- The sampling system is a simple needle valve and flowmeter. Options analogue output provides an easy include: sample pump, fast flow loop means to log results where necessary. system, syringe injection port. Hitech also supply a range of sample conditioning accessories to cater for most sample sources. Applications N Air separation plants N Nitrogen purged soldering systems N Cylinder gas quality N Pharmaceutical and food packaging and storing N Purge gas monitoring N Glove boxes N Workplace air monitoring N Medical monitoring
