Industrial Hygiene (IH) Field Kit Essentials: A Professional Setup Guide

The VelociCalc 9565 by TSI is a multiparameter indoor air quality meter capable of simultaneously measuring air velocity (0–9,999 ft/min), temperature (14–140°F), relative humidity (5–95% RH), CO₂ (0–5,000 ppm), CO (0–500 ppm), and static pressure (±15 in. H₂O) in a single instrument. With onboard storage for over 26,500 samples, it is ideal for HVAC system diagnostics, ventilation assessments, indoor air quality investigations, and comfort studies in commercial and industrial buildings.

It's a multiparameter ventilation meter for HVAC commissioning, test and balance, fume hood and biosafety cabinet testing, cleanroom verification, and IAQ investigations. It measures air velocity, temperature, humidity, static pressure, and optionally CO₂ and CO in a single instrument with interchangeable probes.

Air velocity 0–9,999 ft/min, temperature 14–140°F (±0.5°F), relative humidity 5–95% RH (±3% RH), and static/differential pressure –15 to +15 in. H₂O. When paired with Probe 982, it also measures CO₂ (0–5,000 ppm) and CO (0–500 ppm).

Use a capture hood for direct diffuser CFM readings quickly across many grilles. Use the VelociCalc for velocity traverses, pressure diagnostics, multiparameter troubleshooting, and hood or cabinet testing where a capture hood doesn't apply.

Yes — it supports fume hood and biological safety cabinet face velocity measurements. Confirm your facility's measurement protocol (number of test points, sash position, acceptance criteria) so your measurements match the required method.

Yes — it stores 26,500+ samples across up to 100 test IDs, supporting full commissioning and troubleshooting documentation workflows.

Taking one velocity reading in a turbulent zone and treating it as the representative value. Use a defined traverse or multi-point protocol, allow readings to stabilize at each position, and document probe location and duct geometry.

The meter with selected probe, static pressure probe, neoprene tubing, probe stand, spare batteries, USB cable, AC adapter, TrakPro software and manuals on USB, calibration certificates, and carrying case.

$50/day and $135/week. Pricing beyond two weeks is by quote. For HVAC commissioning, IAQ investigations, or fume hood surveys covering multiple rooms or buildings, the weekly rate provides better value than day rates for any project exceeding three days.
