Protect Your Air

This product is an advanced Carbon monoxide tester that combines high-quality sensor to provide real-time monitoring of Carbon Monoxide (CO), Temperature, Humidity on its digital LCD display.
It combines 3-in-1 functions to help you keep track of the air quality in your home environment, public places, outdoor camping, exploration and other activities and other fields, Ensure more flexible and convenient air quality monitoring. It is easy to operate, with guaranteed quality, and is worth purchasing.

How To Use

Turn On / Off
a) In power-on state, long-press Power Button to turn off the device.
b) In shutdown state, single-press Power Button to turn on the device.
Note : If you can’t turn on the device, please plug in and charge it for a while first.
CO Range (ppm)
CO Detection Range : 0-500ppm
Green Color ( Good ) : 0-100ppm
Orange Color ( Slight ) : 101-200ppm
Red Color ( Serious ) : 201-500ppm
CO Alarm
a) CO alarm value is 100ppm.
b) Single-press Power Button to turn on/off the CO alarm sound.
Temperature Unit
a) Double-press Power Button to switch the temperature unit between Celcius(°C) and Fahrenheit(°F).

Charging

When low battery icon is displayed, the device needs to be charged. Insert the included or another compatible micro USB charging cable into the device. Attach the other end to a USB DC charger (such as a smartphone charger) that outputs DC 5V at >=1000mA. Fully charge for at least 2-3 hours before use. Avoid charging with a USB computer port which only outputs 500mA

Parameter

| Measurement Range| Measurement Method| Resolution| Measurement Accuracy
---|---|---|---|---
CO| 0 – 500 ppm| Electrochemistry| 1 ppm| +10%
Temperature| -10°C – 50°C
(14°F – 122°F)| Semiconductor| 1°C (1.8°F)| ±1°C (±1.8°F)
Humidity| 20% – 85%| Semiconductor| 1%| ±4%

Tips

Tip 1: Strange Readings? Do This:

Turn the device off for some time and then turn it back on again (effectively allowing the monitor to reset).
After continuous use for extended periods, the device may simply need to be reset.
Open a window or bring the device outdoors to allow the sensor to exhaust any accumulated fumes and to allow the readings to adjust back down to more normal levels.

Tip 2:
Not Using It? Turn It Off:
For the most consistently accurate readings and longest product life, it is recommended to turn the monitor off while it is not in use. This will preserve the battery, sensor, and fan.
Tip 3: Open A Window:
Often the quickest and most practical way to get readings back into the desired range is to simply open a window to ventilate more clean outdoor air into your home. This obviously does not apply if you are located in a Wildﬁre area or any other area with compromised outdoor air quality.

Considerations & Precautions

Sampling Frequency:
The sampling frequency of the monitor is 1.5 seconds.
This means that the monitor is providing you with updated readings every 1-2 seconds. Please note that, in order to provide constantly-updated, real-time readings, it contains a continuously running mini fan which gives off a very slight buzzing sound.
Upon turning off the monitor, you will see a brief “ Power Off ” appear on the screen. This is normal. This is not an error message.
This air monitor should be used indoors and kept dry at all times. It is strongly recommended to store in a cool the dry place.
DO NOT expose to sunlight or use in an extremely polluted, dusty, or smoky environment for prolonged periods as doing so may damage the sensors over time.
DO NOT cover the air intake areas during use to avoid inaccurate measurements.
DO NOT use chemicals or solvents to clean the product as residual fumes will skew air quality readings.
DO NOT put water or other liquids on or near the product to avoid electrical damage.
DO NOT allow unauthorized modiﬁcation or repair of this product.
DO NOT take apart or disassemble this monitor. Doing so may damage the product and will invalidate the warranty.
