Waveguide Switches
Waveguide switches are electromagnetic switches with hollow circular or rectangular cross-sections and are used for routing RF energy in microwave communications, broadcasting, and in radar applications. Waveguide switches can be used to transfer both power and communication signals, and the bandwidth of a waveguide is in relation to its size, and thus always referred to by its size (e.g. WR112, WR90, WR75 etc.). Compared to coaxial switches, waveguides can route extremely high power signals over a narrow bandwidth at low to high frequencies, and now Lightweight Waveguide series is available.

Mid-Range Gas Filter Correlation Carbon Dioxide Analyzer
Model T360M
The Model T360M CO2 analyzer measures Carbon Dioxide by comparing infrared energy absorbed by a sample to that absorbed by a reference gas according to the Beer-Lambert law. Using a Gas Filter Correlation Wheel, a high-energy IR light source is alternately passed through a CO2 filled chamber and a chamber with no CO2 present. The light path then travels through the sample cell, which has a folded path of 1.28 meters.The energy loss through the sample cell is compared with the reference signal provided by the filter wheel to produce a signal proportional to concentration, with little effect from interfering gases within the sample. This design produces excellent zero and span stability and high signal to noise ratio, allowing excellent performance over a wide concentration range, making this instrument an ideal choice for CO2 reporting requirements associated with dilution CEMS.All T Series instruments offer an advanced color display, capacitive touch screen, intuitive user interface, flexible I/O, and built-in data acquisition capability. All instrument set up, control and access to stored data and diagnostic information is available through the front panel, or via RS232, Ethernet, or USB com ports, either locally or by remote connection.The Model T360M comes with NumaView™ Software. NumaView™ Remote PC Software allows for a remote connection with virtual interface and data downloading capability to analyzers operating NumaView™ Software.

Humidity Indicators
A humidity detector, also referred to as a humidity meter or humidity gauge, is a device with a humidity sensor that measures the relative humidity in the air. PCE Instruments offers a number of humidity detector products including handheld humidity detector, data recording or data logging humidity detector, and combination or multifunction humidity detector devices that also measure parameters such as room or ambient temperature and atmospheric or barometric pressure. A humidity detector can measure relative humidity (RH) as a percentage (%) from 0 to 100 % RH, depending on the humidity measurement range of the specific model.Humidity is a key factor in everything from library and museum archival to agriculture, construction, manufacturing, transportation, warehousing, and heating, ventilation, air conditioning and refrigeration (HVACR). A relative humidity meter also is helpful in evaluating workers' heat stress risk on production floors and job sites. In addition, humidity plays an important role in the residential sector. If the humidity is too high in a private household, mold can grow. Mold creates a health hazard for anyone breathing the air in the home.

Decibel Meters
A decibel meter is a measuring instrument used to assess noise or sound levels by measuring sound pressure. Often referred to as a sound pressure level (SPL) meter, decibel (dB) meter, noise meter or noise dosimeter, a sound level meter uses a microphone to capture sound. The sound is then evaluated within the device and acoustic measurement values are displayed. Here at PCE Instruments, we offer two types or classes assigned to decibel meters: type 1 / class 1 or type 2 / class 2. For assessing noise in basic industrial, commercial, educational, recreational or residential applications, a type 2 / class 2 decibel meter usually will suffice. For precision-grade assessments often made in a laboratory, a type 1 / class 1 sound level meter primarily is used.

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.
