VOC Monitoring
Instruments

IAQ Detectors, the instrumentation brand of Ace Instruments, manufactures CE certified wall-mount and duct-type VOC detectors for commercial buildings, IVF laboratories, and HVAC systems. Each instrument uses metal oxide semiconductor (MOS) sensing technology and outputs via Modbus RS-485, 4-20mA, or Wi-Fi for BMS integration.

There is no single universal ppb threshold for total VOC (TVOC) across all standards, but application-specific limits exist: ESHRE IVF laboratory guidelines specify a TVOC ceiling of 500 µg/m³ to protect embryo culture environments from off-gassing contamination.

Common applications

Where continuous VOC monitoring is critical

🧪

IVF laboratories

Embryo culture environments require continuous TVOC monitoring below the ESHRE-recommended 500 µg/m³ ceiling to prevent organic off-gassing contamination.

🏢

Commercial buildings

Newly renovated or furnished offices monitor VOC levels to track off-gassing from paints, adhesives, and furnishings.

🏥

Hospitals & labs

Laboratory and sterile processing areas monitor VOC alongside particulate and pressure per ASHRAE 170-2021 provisions.

🏫

Educational institutions

Newly constructed or renovated classrooms monitor VOC during initial occupancy to verify off-gassing has subsided.

🏪

Retail spaces

Retail fit-outs with new flooring, paint, and fixtures monitor VOC levels during and after construction handover.
