Trace-Level UV Fluorescence SO2 Analyzer
Model T100U
-
Teledyne Advanced Pollution Instrumentation
The Model T100U Trace-level SO2 analyzer has been developed specifically to address the challenges of low level monitoring as required, for example, in the US NCore network. It uses the proven UV fluorescence principle, and is designed to allow ultra-sensitive SO2 measurements while still meeting the requirements for use as a US EPA compliance analyzer.The analyzer uses both the light and dark phases of the pulsed UV light source to continuously detect and correct for electronic noise, giving exceptionally stable and sensitive performance. A separate UV detector allows the instrument to continuously correct for variations in lamp intensity. Exceptional stability is achieved with the use of an optical shutter to compensate for PMT drift, and a reference detector to correct for changes in UV lamp intensity. A hydrocarbon "kicker" and advanced optical design combine to prevent inaccuracies due to interferents.

Humidity Detectors
-
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.
