What This Model Is For
The FT0406 Thermo-Hygrometer is an indoor display console that measures temperature from 0 to 60 degrees C and humidity from 10 to 99 percent RH, with a ±1 degree C accuracy for temperature and ±5 percent accuracy for humidity. It records min and max values for both parameters and displays a color-coded comfort icon for humidity. The unit runs on two AAA 1.5V alkaline batteries and is designed to stand freely on a desk or shelf without mounting hardware.
- Measures indoor temperature and humidity with accuracy suitable for home and office environments
- Records min and max values for both temperature and humidity over time
- Colorful humidity comfort icon gives immediate visual feedback on air quality
- Free-standing design allows placement on desks, shelves or counters without wall mounting
- Low power consumption from two AAA batteries supports long-term operation

Where It Is Used
- Home and office environments needing real-time temperature and humidity monitoring
- Retail displays where a visual comfort indicator helps customers assess air quality
- Greenhouse and indoor growing setups requiring basic environmental tracking
- HVAC system integration for basic feedback without a full sensor network
- Cold chain storage units where temperature and humidity trends matter for product integrity
Who It Is For
- Consumer electronics brands adding a basic indoor sensor to an existing product line
- Distributors offering a low-cost environmental monitor for home use
- Agricultural suppliers bundling simple climate tracking with grow lights or fans
- Building services integrators needing a low-cost indoor data point
- Retail chains using the unit as a display item in showrooms or customer zones
Problems It Solves
- Indoor monitors that only show current values without tracking historical highs and lows
- Sensors that lack a visual cue for comfort levels, forcing users to interpret numbers
- Wall-mounted units that require drilling and fixings, increasing installation cost
- Devices that drain batteries quickly due to high power draw or backlighting
- Units that fail to display humidity trends, making it hard to spot dry or damp conditions
Technical Features
- Indoor temperature measurement from 0 to 60 degrees C with ±1 degree C accuracy
- Humidity measurement from 10 to 99 percent RH with ±5 percent accuracy
- Min and max recording for both temperature and humidity
- Color-coded humidity comfort icon for quick visual assessment
- Free-standing design with no mounting hardware required
- LCD display size 53 x 42 mm for clear visibility
- Power draw optimized for two AAA 1.5V alkaline batteries

Materials and Construction
- Moulded plastic housing for the console body
- Battery compartment sized for 2 x AAA cells
- Integrated LCD display with protective cover
How It Is Made
Console sub-assemblies are populated and soldered on our own assembly line
LCD and circuit boards are tested before final housing assembly
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 unit
- Constant temperature and humidity chamber runs covering the 0 to 60 degrees C and 10 to 99 percent RH claims
- Vibration testing to reproduce transport and handling stress
- Smog ageing to check the housing and seals
- Final ageing test on every unit before packing
Customisation Options
- Own-label printing and retail packaging
- Manual and quick start guide in the destination language
- Alternative battery configuration on request
- Console design variants available for brand-specific styling
Compared With the Alternatives
vs Wall-mounted indoor sensors
The FT0406 avoids drilling and fixings, reducing installation effort and cost
vs Sensors with backlighting or high-power displays
The FT0406 uses low power draw, extending battery life without sacrificing readability
vs Units without min/max recording
The FT0406 tracks historical extremes, helping users identify trends over time
Use Guide
- Place the unit in a central indoor location away from direct sunlight and heat sources
- Ensure the LCD is visible from the intended viewing distance
- Insert two AAA alkaline batteries with correct polarity
- Allow 10 seconds after power-up for the unit to stabilize and display readings
- Check battery level periodically; replace when the low battery icon appears
FT0406 Thermo-Hygrometer Questions
What is the real temperature and humidity accuracy
Temperature: plus or minus 1 degree C across 0 to 60 degrees C. Humidity: plus or minus 5 percent across 10 to 99 percent RH.
How long do the batteries last
Battery life depends on usage, but the low power design supports long-term operation with two AAA alkaline cells.
Can I use lithium batteries instead of alkaline
Yes, lithium AAA cells can be used and may extend life in colder environments. Use only the type specified in the manual.
Does it record data over time
Yes, it stores min and max values for both temperature and humidity, which are displayed on the screen.
Is the unit wall-mountable
No, it is designed to stand freely on a desk or shelf. No mounting hardware is included.
What certifications does it carry
TBC. Ask us for the current certificate set for your destination market before you place the order.
