Indoor Air Quality Meters

TSI handheld IAQ meters equip OHS teams to move quickly from complaint to conclusion. Multi-parameter instruments measure PM, CO2, TVOCs, temperature, humidity, and pressure for walkthroughs, ventilation checks, and post-maintenance verification. Intuitive interfaces and reliable sensors help teams pinpoint issues — stuffy rooms, odors, or hot and cold spots — and document corrective actions. Compact, rugged designs travel easily across campuses, healthcare spaces, offices, and public buildings.

When an IAQ concern arises, speed and clarity matter. TSI handheld IAQ meters give OHS professionals the capability to assess conditions on the spot. With multi-parameter measurement in a single device, you can examine complaints, verify ventilation performance, and communicate findings with straightforward data.

Common scenarios:

  • A conference room feels stuffy: Check CO2 and temperature/humidity to evaluate ventilation and comfort.
  • Odor complaints near a copy room: Measure TVOCs and trend readings before and after adjustments.
  • Hot/cold spots between floors: Compare temperature, humidity, and pressure to identify distribution issues.
  • Post-maintenance verification: Capture before/after readings following filter changes or system tuning.

Measurement suite:

  • PM for insight into airborne particles from activities and cleaning cycles.
  • CO2 for occupancy inference and ventilation adjustments.
  • TVOCs for off-gassing and episodic sources.
  • Temperature and humidity for comfort and moisture risk awareness.
  • Differential pressure where directional airflow strategies apply.

Designed for field use:

  • Clear displays and simple menus reduce training time.
  • Rugged housings and protective accessories support daily use.
  • Data logging and export streamline reporting to facilities and leadership.

TSI’s reputation for precision underpins the measurement performance of these meters. Combined with continuous monitoring where needed, OHS teams can create a responsive IAQ program that builds organizational confidence and supports healthy, productive spaces.
