The IAQ Surveyor is a  handheld data-logging instrument designed for IAQ monitoring using 4-function IAQ probe or single-function probes. The Surveyor environmental monitoring system enables you to accurately and reliably measure, datalog and analyze a wide range of important parameters including Humidity, Dewpoint, Airspeed, Differential Pressure, CO, CO2, Temperature, Barometric Pressure, and Gauge Pressure.

Zephyr ll and Zephyr II+ Micromanometers are handheld data logging instrument for monitoring differential pressure and airflow via pitot tube. The Zephyr Multifunction Environmental Meter readily measures temperature, humidity, air velocity, volumetric airflow, dewpoint, and differential pressure.

Smart Four-Function Probe, Three-Function Probe, Air Speed Probes, Pressure and Pitot Tube Probes, Pressure, Liquid/Gas, Barometric, Temperature probes, and Thermocouple Probes.
