Every unit is ageing tested before it leaves the factory
Quality Control
- Rainfall and waterproof testing on the assembled console
- Constant temperature and humidity chamber runs covering the 0 to 60 degrees C claim
- 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

Compared With the Alternatives
vs Wireless indoor sensor with a console
The FT0402 avoids RF pairing and battery drain from wireless transmission, but cannot report data remotely
vs Multi-sensor weather station console
The FT0402 is simpler and cheaper, but lacks humidity and outdoor sensing
vs Wired temperature monitor
No cable run required, but the FT0402 cannot be used in locations where battery replacement is not possible
Use Guide
- Place the console in a central indoor location, away from direct sunlight and heat sources
- Insert two AAA alkaline batteries into the compartment at the back
- Allow 30 seconds after power-up for the unit to stabilize and show initial readings
- Check the min and max values periodically to track temperature trends
- Replace batteries when the low power indicator appears
