Whether developing a gas sensor and testing its sensitivity and repeatability, or calibrating a sensor for quality compliance, you likely will need a traceable reference test gas. Manufacturers of sensors and process regulators require calibration of sensors from time to time.<\/p>\n
Regular calibration assures the detection of conditions such as unwanted, flammable, or toxic gas exposure. Depending on the risks, compliance can prevent process disruption\u2014or even catastrophe.<\/p>\n
Running the mandatory tests using premixed gases is essential to maintaining the integrity of your measurement devices, thus the efficacy, safety, and reliability of your gas flow system.<\/p>\n
[\/et_pb_text][et_pb_heading title=”5 points, or less? Balancing accuracy with cost” _builder_version=”4.27.4″ _module_preset=”default” title_level=”h3″ global_colors_info=”{}” theme_builder_area=”post_content”][\/et_pb_heading][et_pb_text _builder_version=”4.27.4″ _module_preset=”default” custom_margin=”||2rem||false|false” global_colors_info=”{}” theme_builder_area=”post_content”]Many gas sensor calibration procedures standardize a technique that verifies the sensor at less than 5 points in its span. A 2‑point calibration procedure involves two steps: setting the offset reading and calibrating the sensor’s span. Increasing the number of calibration points assures the sensor is performing well across its span. The trade‑off, however, is that it requires multiple pre‑mixed atmospheres which come at a cost.[\/et_pb_text][et_pb_heading title=”Is your premixture commercially available?” _builder_version=”4.27.4″ _module_preset=”default” title_level=”h3″ global_colors_info=”{}” theme_builder_area=”post_content”][\/et_pb_heading][et_pb_text _builder_version=”4.27.4″ _module_preset=”default” custom_margin=”||2rem||false|false” global_colors_info=”{}” theme_builder_area=”post_content”]Gas sensor calibration can often be carried out based on standardized models using readily‑available pre‑mixed gas species. This can be a cost‑effective solution for single‑ and few‑point gas sensor calibration, but it rapidly becomes prohibitively costly when dynamic, multi‑point calibration is required. Made to order m ixtures may also be difficult to find at a reasonable price.[\/et_pb_text][et_pb_heading title=”Should you use a gas mixer instead?” _builder_version=”4.27.4″ _module_preset=”default” title_level=”h3″ global_colors_info=”{}” theme_builder_area=”post_content”][\/et_pb_heading][et_pb_text _builder_version=”4.27.4″ _module_preset=”default” custom_margin=”||2rem||false|false” global_colors_info=”{}” theme_builder_area=”post_content”]<\/p>\n
Often, premixed gases remain an attractive solution for single\u2011 and few\u2011point gas calibration. Multi\u2011point gas sensors, however, often require a more precise solution than premixtures when it comes to calibration.<\/p>\n
Dynamic gas mixers offer much greater performance capabilities when sensors need to be calibrated with a variety of atmospheres, rather than to a single reference standard. This empowers researchers, providing consistent and precise control of gas sensor calibration parameters.<\/p>\n
For instance, gas mixers provide greater levels of control with intuitive firmware. Gas sensor calibration can subsequently be carried out to the parts per million (ppm) range accurately and much more cost\u2011effectively than with pre\u2011mixed cylinders. Simply program the gas mixer and run the process for fully automated, reliable gas sensor calibration.<\/p>\n
