SEE YOUR CO LEVELS FROM 0 PPM

DON'T JUST WAIT FOR AN ALARM. SEE WHAT'S HAPPENING.

Most basic household detectors provide a simple green light to indicate normal operation.

But a green light doesn't tell you the actual carbon monoxide concentration in your room.

This monitor features a clear digital display that shows real-time CO readings beginning at:

0 PPM

Instead of relying exclusively on a warning light, you can see the actual numerical reading and observe changes as they happen.

REAL-TIME DIGITAL DISPLAY

CO readings update approximately every second, allowing you to monitor changing levels directly.

SEE LOW-LEVEL READINGS

The display begins at 0 PPM, giving you visibility into CO readings before conventional high-level alarm conditions are reached.

KNOW MORE THAN JUST GREEN OR RED

See numerical readings instead of depending entirely on a basic status indicator.

GREATER AWARENESS

Understand what your detector is measuring and stay informed about changing indoor conditions.

SEE THE READING. DON'T JUST TRUST THE LIGHT.


FOUR-IN-ONE HOME SAFETY MONITORING

FOUR ESSENTIAL FUNCTIONS. ONE DEVICE.

Why install several separate monitoring devices when one compact unit can monitor four important household conditions?

The integrated system combines:

01 — CARBON MONOXIDE DETECTION

Monitors carbon monoxide and displays real-time concentration readings in PPM, starting from 0 PPM.

Helps you identify changing CO levels around your home.

02 — NATURAL GAS DETECTION

Monitors natural gas levels and provides a visual gas-level indicator.

Designed to help identify potential gas leaks from household gas appliances and connections.

03 — TEMPERATURE MONITORING

Displays the surrounding indoor temperature so you can monitor room conditions.

04 — HUMIDITY MONITORING

Displays relative humidity to give you additional insight into your indoor environment.

ONE DEVICE. FOUR FUNCTIONS.

CO Detection
Natural Gas Detection
Temperature
Humidity

A more comprehensive approach to everyday household monitoring.


PROFESSIONAL-GRADE ELECTROCHEMICAL SENSOR TECHNOLOGY

DEVELOPED WITH INPUT FROM FIREFIGHTERS & GAS SAFE ENGINEERS.

The product was developed with input from Gas Safe engineers and firefighters who understand the importance of reliable household gas monitoring.

At its core is a professional-grade electrochemical CO sensing system.

The original product information describes this as the same type of sensor technology used by Gas Safe engineers during professional callouts.

PROFESSIONAL-GRADE SENSING

Designed for accurate carbon monoxide monitoring.

REAL-TIME PPM MEASUREMENTS

See numerical readings instead of relying solely on a warning light.

CONTINUOUS MONITORING

Keep track of changing indoor CO levels throughout the day and night.

DESIGNED TO AVOID FALSE ALARMS

Professional-grade sensing is designed to identify genuine CO and gas threats rather than reacting to everyday kitchen activity such as toast or steam from a boiling kettle.

PROFESSIONAL SENSOR TECHNOLOGY. MADE FOR EVERYDAY HOMES.


EARLY AWARENESS WITH AUDIBLE SAFETY ALERTS

SEE CHANGING LEVELS. RESPOND WHEN IT MATTERS.

Carbon monoxide can accumulate without producing any visible or detectable smell.

A traditional status light cannot tell you exactly how much CO is present.

This monitor combines continuous digital readings with an audible warning system.

DIGITAL CO READINGS

See CO concentration changes directly on the display.

NATURAL GAS MONITORING

Receive information from the integrated gas-detection system.

AUDIBLE ALARM

The built-in warning system alerts you when the device detects a condition that meets its programmed alarm criteria.

FULL SYSTEM TEST

The dedicated test function is designed to check the complete alarm system rather than simply testing the speaker.

24/7 MONITORING

Keep monitoring active while your family is cooking, relaxing or sleeping.

The system is designed to provide audible warnings when a detected hazard reaches its programmed alarm conditions.

DON'T RELY ON A GREEN LIGHT ALONE.

PROTECT EVERY ROOM. PROTECT EVERYONE UNDER YOUR ROOF.

YOUR FAMILY DESERVES MORE THAN ONE GREEN LIGHT.

A single detector may not provide suitable monitoring coverage throughout an entire home.

Gas appliances, boilers, water heaters and sleeping areas can all require attention.

The recommended placement strategy focuses on:

NEAR THE BOILER

Monitor an important household area where gas appliances and heating equipment are located.

NEAR THE KITCHEN

Keep a detector near the gas hob and other relevant cooking appliances, following the supplied placement instructions.

OUTSIDE BEDROOMS

Provide monitoring in hallways outside sleeping areas.

ON EACH FLOOR

Consider the layout and number of floors when deciding how many units your household needs.

FOR PARENTS & GRANDPARENTS

Extend household monitoring to family members who live independently.

Whether you have children, elderly parents or live alone, knowing your indoor readings can provide additional awareness and peace of mind.

IMPORTANT SAFETY INFORMATION

  • Carbon monoxide is colourless and odourless. Never rely on smell to determine whether it is present.

  • A digital reading of 0 PPM at the detector's location does not guarantee that every room or every area of the property is free from CO.

  • The real-time display and audible alarm serve different purposes. A displayed concentration is not the same as an audible alarm threshold.

  • Do not ignore any audible alarm or unusual CO reading.

  • If a CO alarm activates, move everyone outside into fresh air and follow local emergency-service guidance.

  • If a natural gas leak is suspected, avoid operating electrical switches or creating ignition sources, leave the property and contact the appropriate emergency gas service.

  • Do not remove or disable existing compliant smoke or CO alarms.

  • Install the detector according to the manufacturer's specific instructions and applicable local safety standards.

  • The product page does not specify the exact CO alarm threshold, natural-gas alarm threshold, measurement ranges, electrical ratings or sensor replacement interval. Refer to the final manufacturer's technical documentation for these details.
