What This Model Is For
The FT041A is a wireless pool thermometer that measures water temperature from -40 to +60 degrees C and indoor air temperature from 0 to 60 degrees C, transmitting both readings to a console every 16 seconds over a 433MHz link. It supports up to eight sensors on one console, making it suitable for multi-zone monitoring in residential and commercial pools. The sensor uses four AAA alkaline or lithium cells, with low power consumption extending battery life. The console operates on two AAA alkaline batteries and can be placed freely or hung on a wall.
- Measures pool water temperature from -40 to +60 degrees C, covering freezing and hot summer conditions
- Indoor temperature sensing from 0 to 60 degrees C with ±1 degree C accuracy
- 16 second update interval ensures real-time tracking of temperature changes
- Supports up to eight sensors on a single console, reducing the need for multiple displays
- Low power consumption extends battery life in both sensor and console
Where It Is Used
- Residential pool owners monitoring water temperature for swim comfort and safety
- Commercial pool operators tracking temperature across multiple zones in a facility
- Hot tub and spa integrators needing a reliable wireless temperature display
- Pool maintenance services using the min/max record feature to track thermal trends
- Garden and leisure centre installations where wired sensors are impractical
Who It Is For
- Consumer electronics brands adding a pool thermometer to an existing weather or home monitoring line
- Distributors replacing a wired pool sensor that failed due to moisture or cable damage
- Leisure equipment suppliers bundling a temperature monitor with pool covers or heaters
- Integrators who need a battery-powered sensor for retrofitting into existing pool setups
- Marine and pool equipment brands requiring a low-cost, wireless temperature solution
Problems It Solves
- Wired pool sensors that fail due to water ingress in the cable entry point
- Temperature readings that lag behind real changes due to long update intervals
- Multiple consoles needed when monitoring more than one pool or zone
- Battery drain in cold weather due to poor cell selection or lack of low power design
- Lack of min/max history in basic pool thermometers, making trend analysis impossible
Technical Features
- Measures pool water temperature from -40 to +60 degrees C with ±1 degree C accuracy
- Measures indoor air temperature from 0 to 60 degrees C with ±1 degree C accuracy
- Records and displays min and max temperature values for both pool and indoor sensors
- 12/24 hour digital time display on the console
- High and low temperature alarms on two channels (CH1 and CH2)
- 16 second transmission interval for timely updates
- Supports up to eight sensors on one console
- Free-standing or wall-mountable console design
- Low power consumption in both sensor and receiver

Materials and Construction
- Moulded plastic housing for the pool sensor
- Weather sealed battery compartment sized for 4 x AAA cells
- Integrated solar panel on the sensor body
How It Is Made
Sensor 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
- Constant temperature and humidity chamber runs covering the -40 to +60 degrees C claim
- Vibration testing to reproduce transport and installation loading
- Smog ageing to check the housing and seals
- 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 Wired pool thermometers
No cable run required, but range is limited to 50m in open air
vs Single-sensor consoles
Supports up to eight sensors, reducing cost per monitoring point
vs LoRa-based sensors
433MHz is simpler and lower cost; LoRa is better for long-range or multi-site deployments
Use Guide
- Mount the sensor in the pool water at a depth where temperature is stable, avoiding surface or bottom layers
- Ensure the sensor is not blocked by pool skimmers or filters
- Use lithium cells in cold climates to maintain performance below freezing
- Pair the sensor with the console before submerging it
- Check the battery compartment seal annually and clean the sensor body to prevent debris buildup
FT041A Wireless Pool Thermometer Questions
What is the real range between the sensor and the console
50 meters in open air. Through walls or pool equipment, expect reduced range, typically 20 to 30 meters.
How often does it update
Every 16 seconds, which is frequent enough to track temperature changes during heating or cooling cycles.
Can I use lithium cells in the sensor
Yes. Lithium cells are recommended for cold weather or long-term use to maintain performance below freezing.
Can it work with a console we already sell
If that console is on the UCTECH 433MHz protocol, yes. Send us the model and we will confirm before you order.
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.
