Cheap voc sensor for air purifiers and ventilation system tgs2600 Model number: tgs2600 1.Features: * low power consumption * high sensitivity to gaseous air contaminants * long life and low cost * uses simple electrical circuit * small size 2.Description The sensing element is comprised of a metal oxide semiconductor layer formed on an alumina substrate of a sensing chip together with an integrated heater. In the presence of a detectable gas, the sensor's conductivity increases depending on the gas concentration in the air. A simple electrical circuit can convert the change in conductivity to an output signal which corresponds to the gas concentration. The tgs 2600 has high sensitivity to low concentrations of gaseous air contaminants such as hydrogen and carbon monoxide which exist in cigarette smoke. The sensor can detect hydrogen at a level of several ppm. Due to miniaturization of the sensing chip, tgs 2600 requires a heater current of only 42ma and the device is housed in a standard to-5 package. 3 applications * air cleaners * ventilation control * air quality m onitors

IoLine High Performance pH Electrodes Iodine glass pH electrodes with temperature sensor IoLine-HPB IoLine High Performance pH Electrodes Description The IoLine high performance pH electrodes use a patented three chamber system with an iodine reservoir in the iodine/iodide reference electrode. The standard hydrogen electrode has proven too difficult in practical use to gain more than a mere theoretical importance. The Ag/AgCl reference system, which is the most common reference system, can cause measuring instabilities originating from potential variations with changing temperature or reactions between silver ions and the measuring solution in the area of the diaphragm. IoLine pH electrodes, in contrast, have the advantage of a much lower temperature sensitivity and a metal ion free reference system. IoLine-HPB IoLine High Performance pH Electrodes Features * Unique iodine/iodide reference system * Tris buffer compatible * Exchangeable bridge electrolyte * Integrated refill port * Excellent for a wide range of applications * Integrated temperature sensor IoLine-HPB IoLine High Performance pH Electrodes Specifications * pH Range: 0 to 14 * Temperature Range: 23 to +212'F (-5 to +100'C) * Shaft: Glass * Zero Point: pH = 7.00 +/- 0.25 * Reference System: iodine/iodide
