Breathe easier.

CNRY watches the air so you can focus on the work.

CNRY formaldehyde sensor in Arterial White, with its status light glowing green

A rechargeable personal formaldehyde sensor the size of a paper test sensor. Clip it on, pair it with your phone, and know your exposure in real time.

Impossibly small

The size of a paper test sensor.

The paper badges you've used for years only tell you about yesterday. CNRY is about the same size, but it measures continuously, alerts instantly, and remembers everything.

CNRY, front view 48.6 mm 48.6 mm
CNRY, side view showing the USB-C port 16 mm

Small device.
Serious awareness.

Bluetooth to your phone.

Pairs in seconds. Live readings and history live in the CNRY app on iPhone and Android.

Charges over USB-C.

No batteries to swap, no strips to throw away. Use the same cable as your phone and laptop.

Every exposure, logged.

CNRY records continuously and syncs to your phone, so you have a clear record of every case.

Light and sound alerts.

A glowing status bar and audible tones tell you when levels rise, even with gloves on and eyes on the table.

Visual + audible cues

Green. Amber. Red.
Instantly obvious.

CNRY's status bar changes color as concentration rises, and audible alerts escalate with it. You don't have to look at your phone to know.

Status light green: clear Status light amber: caution Status light red: alert

Alert thresholds are referenced to OSHA 29 CFR 1910.1048: action level 0.5 ppm (8-hr TWA), PEL 0.75 ppm (8-hr TWA), STEL 2 ppm (15-min). Final thresholds and certifications will be published at launch.
