HSE is the exclusive North American distributor for products manufactured by TEL, Temperature Electronics Ltd. of Glossop, England. TEL makes air flow monitors for laboratory fume hoods and bio-safety cabinets, VAV fume hood control products (including room pressure controls and fresh air bleed controls) and room pressure monitors. Contact HSE at 847-680-9930. Founded in 2003, Holland Safety Equipment is a family-run business based in Chicago’s north suburbs. Our main customers are manufacturers of fume hoods and bio-safety cabinets, as well as fume hood and BSC certifiers and technicians and end users in any laboratory application — including education, health care/medical, pharmaceutical, petro-chemical, R&D and production process labs. Many fume hoods and bio-safety cabinets come with factory-installed TEL monitors. If you have a hood or cabinet without a monitor, or would like to replace an existing monitor with a TEL product, please contact us at 847-680-9930 for more information or request a quote, or continue to browse through our Web site. The TEL monitors typically can be field installed and calibrated in an hour or less. In addition to TEL products, HSE also offers room pressure monitors for critical environments, smoke sources for airflow visualization, a static pressure alarm for hazardous laboratory environments and other related products.
