Look here for instrumentation for monitoring and assessing chemical exposure in the workplace, as regulated by OSHA Permissible Exposure Limits (PELS).

HVAC instruments are an integral part of enhancing the comfort, safety, and operating efficiency of indoor environments. Look here for temperature and humidity meters, air velocity instruments, ventilation meters, and combustion analyzers.

IAQ problems can be caused by poor ventilation, biological growth, dust, odors, volatile organic compounds (VOC), combustion emissions, and respirable particles. RAECO has instrumentation to measure, monitor and analyze the toughest IAQ problems, so you can find their sources, and correct them.

Meet OSHA and DOD standards for allowable noise levels. Check out Casella USA's line of sound level meters and dosimeters.

Look for A.P. Buck personal sampling pumps and datalogging, validated sampling pumps here. We've got them! Don't forget about flow calibrators. Buck, Bios, and Sensidyne/Gilian pumps and their accessories are all available here.

RAECO is your source for TSI CaCalc combustion efficiency analyzers and stack gas emissions monitors. Truly light-weight and portable, the CaCalc 6200 series calculates efficiency, excess air, CO2, and emission rates. It also provides NO2 values and has an adjustable CO high limit pump shutdown to protect the CO sensor.

Employees who are exposed to long periods of heat and high humidity are susceptible to heat stress illnesses. NIOSH, ACGIH, and the EPA have developed recommended safety guidelines for working in hot environments. Look here for Testo and Casella USA test instrumentation.

PORTACOUNT® Plus is the easy way to reliably fit test tight-fitting respirators. The PORTACOUNT uses a quantitative fit testing method to make a direct measurement of respirator fit factors.
