Air Sampling and Monitoring Products
HI-Q Environmental Products Company manufactures a wide range of NIST traceable Air Flow Calibrators & In-Line Adapter Fittings. From rugged steel constructed housings to precision machined venturi tubes, HI-Q’s line of air flow calibrators are the most durable & dependable calibration devices available.
Carbon & Silver Zeolite Cartridges: HI-Q manufacturers all of its cartridges under an ISO 9001:2000 Certified quality assurance program. In addition to our strickt Quality Assurance Program, HI-Q specifically has each individual lot of carbon and silver zeolite, from which the individual cartridges are made, randomly tested and certified by an independent testing laboratory at multiple sample flow rate points through the most common geometry of cartridges utilized in the nuclear industry. The Lot-Specific test results are included with each customer order.
Filter Paper for Air Sampling: HI-Q stocks a very wide range of high-efficiency filter paper used in the collection of particulate. HI-Q supplies custom punched sizes from 25 mm diameter all the way up to 24” x 24” sheets in media ranging from Glass Fiber to Cellulose.
HI-Q's product line includes complete stack sampling systems, consisting of a specified type of probe, in-line filter holder, the transport line, sampling pump and flow controller. We recommend, design, and supply complete systems. HI-Q is able to make stack-sampling system design suggestions by receiving your sampling requirements and operating conditions.
HI-Q offers a calibration and re-certification service for air flow calibrators and air sampling instrumentation. HI-Q calibrates and certifies units against a N.I.S.T. traceable laminar flow element and furnishes a certification of accuracy with each unit. HI-Q also offers complete repair & retrofitting services for your existing air sampling equipment, systems or accessories. Feel free to call or write for a quote on the repair or retrofitting of any of your existing air sampling equipment, systems or accessories. Maintenance & Design Service Contracts Available.
The PAM series of portable meters are compact, lightweight, hand-held instruments used to measure surface contamination from alpha, beta, and gamma activity. Low maintenance scintillation detectors are used to measure the contamination. Dual phosphor detectors with electronics are available for discrimination of alpha from beta activity.
The RADNET monitor is equipped with an integrated dual detector that measures beta and gamma pacticulate isotopes deposited on a filter paper by means of a multi-processing technique. The beta detector is a rugged, ion-implanted, silicon detector with 600mm2 of sensitive surface area coupled to a charge pre-amplifier and processor-based MCA module that is able to detect and measure beta radiation. The gamma detector is a 2”x2” NaI(TI) detector with gain stabilization and automatic temperature control. The sodium iodide detector is coupled to a tubebase, charge preamplifier high voltage power supply and to a second MCA module. The local processing unit using serial interfaces communicates with the two MCA modules, the mass flow controller and the weather data logger. The detectors are coaxial with the silicon detector close to the filter paper, in front of the sodium iodide detector to enhance its beta sensitivity. The local processing unit manages all input and output functions and performs calculations for real-time radiation monitoring and sample flow control. Also serving functions for local and remote interfacing, the local processing unit performs auxiliary datalogging, processing, data backup,on-line and offline testing,and data communication(telemetry).
