Why FloCal-30
Three reasons it replaces
your existing calibrator.
01 / ACCURACY
NIST-traceable field accuracy
±1.5% below 2 SLPM and ±1% at or above 2 SLPM, maintained from −20°C to 60°C across the full 0.5–30 SLPM range. One device covers every standard FRM and FEM ambient air sampler — low-volume to high-volume.
02 / MOBILITY
Pocket-sized field hardware
15.2 oz aircraft-grade aluminum body at 2.7" × 4.7" × 1.3". USB-C recharge in 4.5 hours. Five tactile keys designed for gloved hands.
03 / WALK-AWAY MONITORING
Live mirror on your phone
Bluetooth mirrors the FloCal-30 display in real time — same readings, same units. Step away from the sampler and keep your eyes on the data.
Field calibration, fixed
Built to eliminate the friction of field work.
Every spec on this page traces back to a problem technicians actually have on-site.
Crouching to read the display
Bluetooth streams readings directly to your phone
Calibrators that fail in cold
Rated −30°C to 60°C, 0–100% RH non-condensing
Hauling a bulky calibrator
15.2 oz · 2.7" × 4.7" — fits in a jacket pocket
Cables snaking through trailers
Bluetooth keeps you in range — no cables, no setup
Engineered for the field
Precision in every detail.
From the flow accuracy spec to the size of the buttons — every choice was engineered for ambient air monitoring.
Full 0.5–30 SLPM range
0.01 LPM resolution catches the small deviations that matter for compliance work. One calibrator covers every standard FRM and FEM sampler — PM2.5, PM10, TSP, low- to high-volume.
18-hour battery, USB-C charging
7.4 Wh lithium-ion runs continuously through a full field day. Recharges in 4.5 hours via standard USB-C — no proprietary chargers.
Aircraft-grade aluminum body
Machined housing with brushed stainless fittings. 15.2 oz at 2.7" × 4.7" × 1.3" — pocket-sized and rated for −30°C to 60°C operation.
Sunlight-readable display
2.3" TFT LCD at 320×240 shows volumetric flow, standard flow, temperature, RH, and barometric pressure on one screen — no menus to navigate.

Companion app
Readings follow you,
not the other way around.
The FloCal app mirrors the device display in real time — the same readings, the same units, on your phone instead of the LCD.
01
Live mirroring
See volumetric and standard flow exactly as the device shows it — over Bluetooth, in real time.
02
Walk-away monitoring
Step away from the sampler and keep your eyes on the readings within Bluetooth range. No crouching, no cables.
03
No setup, no account
Open the app, tap your FloCal-30, and you're mirroring. Nothing else to configure.

Where it's used
Built for the field,
not the bench.
Wherever EPA reference samplers are deployed, FloCal-30 is the right tool for flow verification.
Ambient Monitoring Networks
Rooftop stations, roadside monitors, remote sites. One pocket-sized device handles every sampler on your route.
Mobile Trailers
Wireless readout eliminates cable routing in cramped enclosures. Walk-away monitoring keeps you out of awkward positions.
FRM & FEM Compliance
NIST-traceable calibration for PM2.5, PM10, TSP, and high- and low-volume samplers — out of the box.
Multi-Sampler Sites
0.5–30 SLPM range covers low- to high-volume on a single device — no second calibrator needed.
Cold-Weather Deployments
Rated to −30°C with ±1% accuracy maintained from −20°C to 60°C. Tactile keys work with gloves on.
Field Spot Checks
Fast setup and instant pairing — quick verifications without disrupting ongoing sampling operations.
