What This Model Is For
The FT0405 Probe Thermometer measures indoor air temperature and probe temperature from -40 to +60 degrees C, with a 1-meter waterproof cable connecting the console to the probe. It records min and max values for both temperature and humidity, and uses two AAA batteries to power the console. The display is designed for standalone use, with a compact form factor and clear LCD readout. It is built for environments where temperature monitoring must continue through short power interruptions or in areas where wired sensors are not feasible.
- Measures both indoor air and probe temperature across a wide range from -40 to +60 degrees C
- 1-meter waterproof cable allows safe use in wet or humid environments
- Records min and max values for temperature and humidity to track trends over time
- Standalone console with no need for a smartphone or app to view readings
- Two AAA batteries power the console, enabling long-term operation without mains

Where It Is Used
- Food storage and cold chain monitoring in retail refrigerators and walk-in coolers
- Greenhouse and hydroponic systems where soil or water temperature affects plant growth
- HVAC and building services diagnostics during commissioning and maintenance
- Home and small business use where a simple, reliable thermometer is needed
- Laboratory or workshop settings requiring a portable temperature logger
Who It Is For
- Distributors selling standalone thermometers to retail or industrial buyers
- HVAC integrators needing a low-cost temperature monitor for site checks
- Agricultural suppliers bundling sensors with irrigation or climate control systems
- Food service operators monitoring storage conditions without digital infrastructure
- Brand product managers adding a probe thermometer to a multi-sensor kit
Problems It Solves
- Thermometers that only measure air temperature and cannot track probe or liquid temperature
- Cables that fail in wet environments due to lack of waterproofing
- Sensors that lose data during power outages or battery changes
- Systems that require a smartphone or app just to read a temperature
- Inconsistent accuracy across the full temperature range, especially below zero
Technical Features
- Indoor temperature range: 0 to 60 degrees C
- Probe temperature range: -40 to +60 degrees C
- Temperature accuracy: plus or minus 1 degree C across the full range
- Humidity measurement with min and max recording capability
- 1-meter waterproof cable connecting console to probe
- Standalone console with LCD display for real-time readings
- Min and max data retention for temperature and humidity
- No external power required for operation, only two AAA batteries

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 tested for continuity and waterproof integrity
Housings are sealed and checked on rainfall and waterproof test equipment
Every unit undergoes a final ageing test before packing
Quality Control
- Rainfall and waterproof testing on the assembled probe cable
- Constant temperature and humidity chamber runs to verify performance across the -40 to +60 degrees C range
- Vibration testing to simulate transport and site installation stress
- Smog ageing to assess long-term seal and housing durability
- Final ageing test on every unit before packaging
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 firmware adapted to match a customer’s existing display protocol
Compared With the Alternatives
vs Thermometers with no probe or only air temperature
The FT0405 adds a probe for accurate measurement of liquids, soil, or surfaces
vs Wired sensors requiring a permanent cable run
The 1-meter cable allows flexibility in placement without fixed wiring
vs Smartphone-connected thermometers
No app or internet required; ideal for locations without digital infrastructure
Use Guide
- Place the console in a dry, visible location with clear line of sight to the probe
- Insert the probe into the material or environment being monitored, ensuring full contact
- Avoid exposing the probe to direct sunlight or extreme ambient heat during measurement
- Replace batteries when the low power indicator appears to maintain data logging
- Clean the probe tip with a dry cloth before each use to avoid contamination
FT0405 Probe Thermometer Questions
What is the maximum distance between the console and the probe
The cable is 1 meter long. There is no wireless range; the connection is direct via the cable.
Can the probe measure liquid temperature
Yes. The probe is designed to measure temperature in liquids, soil, or other materials.
How accurate is the temperature reading
The temperature accuracy is plus or minus 1 degree C across the full range of -40 to +60 degrees C.
Does it record data over time
Yes. It stores min and max values for both temperature and humidity, which can be reviewed at any time.
What batteries are used and how long do they last
Two AAA 1.5V alkaline batteries power the console. Battery life depends on usage but is designed for months of continuous operation.
Can I get this with a different language manual
Yes. We provide manuals in the destination language upon request. Contact [email protected].
