3D Inspection Service
-
The reference data may come in the form of a table, with values at specific points or features, a cad model, or 3d scan. 3D inspection services may require datum measurements, where the part to be inspected is located in a fixture that is specifically designed to orient the part by an ordered method. In some cases, the part may have features that are designed specifically to be referenced by datums, if no functional feature of the part provides a clear reference.

Gas Filter Correlation CO Analyzer
Model N300
-
Teledyne Advanced Pollution Instrumentation
The Model N300 is a microprocessor-controlled analyzer based on the Beer-Lambert law that is used to determine the concentration of carbon monoxide (CO) in a sample gas.The N300 uses Gas Filter Correlation (GFC) to overcome the interfering effects of various other gases (such as water vapor) that also absorb Infrared (IR) light. The analyzer passes the IR light beam through a spinning wheel made up of two separate chambers: one containing a high concentration of CO known as the reference, and the other containing a neutral gas known as the measure. The concentration of CO in the sample chamber is computed by taking the ratio of the instantaneous measure and reference values and then compensating the ratio for sample temperature and pressure.

Hygrometers
-
A hygrometer is a device used to measure humidity. Many hygrometer products also measure temperature. A hygrometer that measures both humidity and temperature often is referred to as a thermo-hygrometer. PCE Instruments (PCE) offers a wide variety of hygrometer products used to measure the relative humidity of the air.Since humidity is an important factor in many sectors including but not limited to manufacturing, agriculture, construction, restoration, remediation and heating, ventilation and air conditioning (HVAC), PCE also carries a number of hygrometer devices designed for specific applications such as measuring the humidity in bales of pressed hay or in rolls of paper. A hygrometer also can be used to evaluate heat stress risk in hot work environments like boiler rooms, factories, construction sites and commercial bakeries. To accurately assess heat stress risk, a hygrometer capable of detecting and classifying temperature in relation to the amount of moisture content in the air is recommended. The global standard description for heat stress is the Wet Bulb Globe Temperature Index (WBGT). A combination hygrometer / thermometer, or thermo-hygrometer, can be used to verify the integrity of the cold chain during the transport and warehousing of refrigerated food and pharmaceutical products. This versatile and popular style of hygrometer also is ideal for evaluating the performance of HVAC systems in industrial, commercial and residential properties. If the humidity indoors is too high, mold can occur. Certain types of mold cause respiratory problems and other negative health effects for people living or working in the surrounding environment. In addition, mold that has permeated into the walls or roof of a structure must be removed for safety reasons. Mold remediation and removal, also called mold damage restoration, can be a costly endeavor, which is why preventative monitoring of the humidity indoors is preferable whenever possible.
