What This Model Is For
The FT0418 is a wireless thermometer system that measures indoor temperature and humidity, plus fridge and freezer temperatures across a wide range, then sends readings to a console every 60 seconds over a 433MHz link. It records min and max values and triggers alarms when temperature exceeds set limits. The system uses two AAA batteries in the sensor and two in the console, with a bright green backlight for visibility in low light. It can stand freely or be mounted on a wall, making it suitable for kitchens, pantries, and storage areas where temperature control matters.
- Measures indoor, fridge, and freezer temperatures with a single sensor system
- 60 second transmission interval keeps readings current without overloading the RF link
- 50 meter open area range covers most homes and small commercial spaces
- Bright green backlight improves readability in dim conditions
- Free standing or wall mount options allow flexible placement without tools

Where It Is Used
- Home kitchens and pantries where food safety depends on consistent fridge temperature
- Small retail cold storage units needing a low-cost monitoring solution
- Garage or basement storage areas for tools, paint, or chemicals sensitive to cold
- Breweries and home fermentation setups requiring temperature tracking
- Cold chain logistics for small shipments where a wired system is not feasible
Who It Is For
- Consumer electronics brands adding temperature monitoring to an existing console line
- Distributors replacing a basic thermometer that lacks alarm or min/max tracking
- Retail chains needing a low-cost, easy-to-install temperature monitor for display cases
- Home appliance integrators bundling sensors with refrigeration units
- Horticultural or greenhouse operators monitoring storage zones for seed or plant material
Problems It Solves
- Temperature monitoring systems that only track indoor air, missing fridge or freezer conditions
- Sensors that update every 5 minutes or more, missing short temperature spikes
- Console systems that lack alarms or min/max history, requiring manual checks
- Units with dim or no backlight, making readings hard to see at night
- Solutions that require wall mounting or wiring, increasing installation time and cost
Technical Features
- Indoor temperature and humidity sensing from 0 to 60 degrees C
- Fridge and freezer temperature sensing from -40 to 60 degrees C
- Min and max temperature recording with automatic tracking
- High and low temperature alarms triggered when limits are exceeded
- 60 second transmission interval to the console over 433MHz RF
- Bright green backlight for LCD visibility in low light
- Free standing or wall hanging installation options
- LCD display size 76 x 45 mm with clear numeric readouts
- Supports both Celsius and Fahrenheit units, selectable on the console

Materials and Construction
- Moulded plastic housing for the indoor console and remote sensor
- Weather sealed battery compartment sized for 2 x AAA cells
- Integrated LCD screen with green backlight for visibility
How It Is Made
Sensor and console sub-assemblies are populated and soldered on our own assembly line
Housings are sealed and checked on rainfall and waterproof test equipment
Every unit is ageing tested before it leaves the factory
Quality Control
- Rainfall and waterproof testing on the assembled sensor and console
- Constant temperature and humidity chamber runs covering the -40 to +60 degrees C range
- Vibration testing to simulate transport and mounting stress
- Smog ageing to verify housing and seal integrity
- Final ageing test on every unit before packing
Customisation Options
- Own-label printing and retail packaging
- Console pairing to a customer's existing UCTECH-protocol display
- Alternative battery configurations on request
- Manual and quick start guide in the destination language
Compared With the Alternatives
vs Separate indoor and fridge sensors
One sensor system reduces mounting points and battery count, but you cannot place the fridge sensor in a different room
vs Wired temperature monitoring systems
No cable run required, but the battery-powered sensor has a limited lifespan compared to a wired unit
vs LoRa-based sensors in our FT0310 and FT0832 range
433MHz is simpler and cheaper for a single room; LoRa is better for long-range or multi-site monitoring
Use Guide
- Place the indoor console in a central location away from direct sunlight or heat sources
- Mount the fridge sensor inside the appliance, away from the door and cooling vents
- Use lithium batteries in the sensor if the environment drops below 0 degrees C
- Set the high and low alarm thresholds based on the stored item's tolerance
- Check the battery level indicator on the console monthly and replace batteries as needed
FT0418 Wireless Thermometer Questions
What is the real range between the sensor and the console
50 meters in open air. Through walls and cabinets, expect around 15 to 20 meters, which covers most homes and small storage areas.
How often does it update
Every 60 seconds, which is frequent enough to catch temperature changes without overwhelming the RF link.
Can the sensor work in a freezer below zero
Yes, it is rated from -40 to +60 degrees C, so it works in standard freezers and deep freeze units.
Does it support both Celsius and Fahrenheit
Yes, the console allows switching between Celsius and Fahrenheit units.
What is the lead time and minimum order
Tell us the quantity and target ship date and we will confirm both by email. Lead time depends on whether own-label printing and packaging are involved.
Which certifications does it carry
TBC. Ask us for the current certificate set for your destination market before you place the order.
