Used CORNING PC-420 #9215852 for sale

CORNING PC-420 is a lab equipment and accessory used in various research laboratories and lab-grade experiments. It is designed to provide precise and accurate measurement of gas concentrations in samples of liquids, gases, and vapors. This device features a stainless steel, platinum, or nickel-plated alloy head, a precision micro-pressure gauged gas reservoir, and two glass vacuum ports for easy adding and removing of air or gas to the sample chamber. The device works by using a gravity method for measuring the gas concentration in a sample. It utilizes a two-port equipment in which the sample enters the gauge head through the upper port. The lower port is then used to vent off the sample before and after the measurement. This process allows the sample size to remain constant and simplifies the process of measuring gas concentration in the sample. Once the sample has been introduced into the system, the micro-pressure gauged reservoir allows precise control over the desired gas concentration in the sample. The user can then open the stainless steel control knob located on the top of the device to decrease or increase the gas concentration in the sample. The adjustment range of PC-420 allows for measurements as low as 5% of atmospheric pressure up to 25% of atmospheric pressure. Furthermore, the accuracy of CORNING PC-420 is extremely high and accurate to up to 0.05% sensitivity. It can also be equipped with remote sensing technology, enabling users to adjust gas concentrations from a compatible laboratory computer. This advanced feature ensures that experiments can be monitored and adjusted in real-time. PC-420 is also equipped with an easy-to-use calibration procedure. This process requires only a few drops of water to be added to the sample, and the results are then automatically logged into the unit. With its advanced features and easy-to-use calibration machine, CORNING PC-420 is the perfect choice for researchers looking for accurate and precise measurements of gas concentrations in samples.
