AVT-200

FEATURES

RUGGED CONSTRUCTION
DIRECT READING -/+ IN CFM OR LPM
BETTER THAN +5% ACCURACY OF READING
COMPATIBLE WITH TELEMETRY SYSTEM
CERTIFIED AND TRACEABLE TO NIST

RADēCO AVT-200 is the most durable and repeatable air volume totalizing device available. The RADēCO totalizer converts the inlet vacuum of the air sampler to a unit of measure (CFM/LPM). The totalizer allows the user to toggle between the current flow rate and total volume sampled. Compatible with any RADēCO constant low air sampler. Also designed for use with RADēCO Telemetry System. Simple, cost effective and consistently accurate year after year.

The RADēCO AVT-200 is available calibrated in cubic feet per minute or in liters per minute. Each totalizer is individually calibrated to an air flow instrumentation system whose calibration is certified and traceable to the National Institute of Standards and Technology (NIST). The RADēCO Air Flow Calibrators are guaranteed to an accuracy of better than +5%, referenced to 29.92 inches of mercury and 70°F. A Certificate of Calibration is supplied with each calibrator.

RADēCO maintains a recertification and repair service for all RADēCO units. Special calibrations are available upon request.

AVT-200 and Telemetry

The AVT-200 outputs a voltage signal to the RADēCO Telemetry RTU which is proportional to the flow rate of the air sampler. If the air sampler were to lose flow, the AVT-200 would automatically shut down. The signal to the RTU is then lost and will generate an automatic notification to the designated user.

In the event of loss of power to the AVT-200, the total volume sampled in memory is not lost. This allows the user to view the total volume sampled until the time of power loss. Restoring power will not reset the total volume in memory.
