Product Description

INDOOR AIR QUALITY METERS

includes: Instrument, hard carrying case, (4) AA alkaline batteries, operation and service manual and NIST calibration certificate. Models 7525 and 7545 include LogDat2 downloading software with USB cable and AC adaptor

PRODUCT DETAILS:

TSI IAQ-Calc Meters are outstanding instruments for investigating and monitoring indoor air quality (IAQ). Model 7515 is a cost-effective meter for carbon dioxide (CO2) measurements. Models 7525 and 7545 simultaneously measure and data log multiple parameters. Model 7525 measures CO2, temperature, humidity, and calculates dew point, wet bulb temperature, and percentage outside air.

Model 7545 adds detection of carbon monoxide (CO).

FEATURES AND BENEFITS:

  • Low-drift NDIR CO2 sensor for stable, accurate readings
  • Sampling function records multiple point measurements
  • Ergonomic, over molded case design

Application:

  • Verify building HVAC system performance
  • Examine building IAQ conditions to optimize worker productivity
  • Comply with regulations and guidelines

Includes: Instrument, Hard carrying-case, (4) AA alkaline batteries, Operation and service manual, NIST calibration certificate
