What This Model Is For
The FT0422 Probe Thermometer measures indoor air temperature and probe temperature from -40 to +60 degrees C, with a 1m waterproof cable connecting the probe to the console. It records min and max temperature values and transmits readings every 16 seconds over a 433MHz link. The console runs on two AAA batteries and displays both temperature values on a 52 x 41mm LCD. The probe is designed for use in food storage, refrigeration, and industrial environments where a direct contact reading is needed.
- Measures both indoor air and probe temperature on the same display
- 1m waterproof cable allows safe immersion or placement in tight spaces
- Records min and max values for trend tracking without a data logger
- 16 second update interval ensures readings reflect real-time changes
- 433MHz transmission reaches up to 100m in open air without a gateway

Where It Is Used
- Cold storage monitoring in food distribution warehouses
- Refrigeration unit maintenance checks for HVAC technicians
- Industrial process monitoring where surface temperature varies
- Home kitchen use for checking meat or dough temperature
- Greenhouse or nursery temperature profiling in soil or water
Who It Is For
- Consumer electronics brands adding a probe thermometer to an existing console line
- Distributors replacing a probe sensor that failed after exposure to moisture
- Food safety integrators needing a low-cost temperature tracking tool

- Industrial equipment suppliers bundling sensors with monitoring kits
Problems It Solves
- Probe sensors that fail when the cable gets wet or damaged
- Console-only temperature readings that miss surface or material differences
- Manual logging that misses transient temperature spikes
- RF links that drop out when the sensor is more than 30m from the console
- Lack of min/max memory in basic thermometers that require constant monitoring

Materials and Construction
- Moulded plastic housing for the console
- Integrated battery compartment sized for 2 x AAA cells
- Waterproof cable with a sealed connection at the probe end
How It Is Made
Console and probe sub-assemblies are assembled on our own production line
Cable connections are soldered and tested for continuity
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 probe and cable
- 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 cable and housing integrity
- Final ageing test on every unit before packing
Customisation Options
- Own-label printing on the console and packaging
- Manual and quick start guide in the destination language
- Alternative battery configuration on request
- Console pairing to a customer's existing UCTECH-protocol display
Compared With the Alternatives
vs Probe thermometer with non-waterproof cable
The 1m waterproof cable allows safe use in wet environments without risk of shorting or failure
vs Wired probe thermometer with no min/max memory
The FT0422 records min and max values, reducing the need for manual logging
vs LoRa-based probe sensor
433MHz is simpler and lower cost for short-range applications; LoRa is better for large sites
Use Guide
- Place the probe in the target environment before turning on the console
- Ensure the cable is not kinked or pinched where it enters the console
- Use the console in a stable location to avoid false readings from movement
- Check the battery level if readings stop updating
- Reset min/max values by holding the button for 3 seconds
FT0422 Probe Thermometer Questions
What is the real range between the probe and the console
100m in open air. Through walls or inside a building, expect around 30m, which covers most indoor and small outdoor setups.
How often does it update
Every 16 seconds, which is frequent enough to track rapid temperature changes without overwhelming the display.
Can the probe be used in water or liquids
Yes, the probe is designed for immersion in liquids, but the cable must remain dry and the connection sealed.
Does it work with a console we already sell
If your console uses the UCTECH 433MHz protocol, yes. Send us the model number 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.
