We offer free standard shipping to every province and territory in Canada. No minimum purchase is required, and all orders include tracking for your convenience.
You may return most new, unopened items within 30 days from delivery for a full refund. We'll also pay the return shipping costs if the return is a result of our error (you received an incorrect or defective item, etc.).
You should expect to receive your refund within four weeks of giving your package to the return shipper, however, in many cases you will receive a refund more quickly. This time period includes the transit time for us to receive your return from the shipper (5 to 10 business days), the time it takes us to process your return once we receive it (3 to 5 business days), and the time it takes your bank to process our refund request (5 to 10 business days).

Deliveries to Canada’s outer and remote regions may experience seasonal delays caused by severe weather or limited carrier availability. We appreciate your patience and recommend allowing additional time for your order to arrive safely.
Meet the HAKINAKU 3-in-1 Portable CO Detector, a palm-sized companion that tracks carbon monoxide, ambient humidity, and temperature. Its sleek 3.5 x 2.2 x 0.66 inch body fits comfortably in your hand, while an HD display presents real‑time readings clearly for quick awareness.
This device combines three sensors in one compact unit. CO is measurable from 0 to 1000 ppm, humidity from 0% to 95% RH, and temperature from -4 to 140 °F. The high-contrast screen makes each value easy to read at a glance, even in dim environments.
Alarm patterns respond to detected CO levels. Alerts escalate as readings rise: lower ranges trigger multiple alerts within minutes, mid ranges increase frequency, and higher levels shift toward continuous notification. This helps you stay informed as conditions change.
Powered by a 1000 mAh battery, the detector can run a long time, especially in power‑saving mode. The screen automatically sleeps after 30 seconds, while monitoring continues in the background, extending operational time without sacrificing awareness.
Designed for on‑the‑go use, it includes a lanyard, a kickstand, and a screw hole for wall mounting. Place it on a desk, hang it in a tent, or affix it to a wall or shelf—wherever you need a quick environmental read.
Safe testing can be done with a small smoke source such as burning paper to observe readings on the HD display. For meaningful results, avoid testing with distant or very low emission sources.
Perfect for indoor spaces like kitchens and bedrooms and also suitable for outdoor adventures such as camping, RV trips, boats, or hotel stays. Its compact form minimizes clutter while delivering essential environmental data.

Q: How long does the battery last and how does power saving work?
