Frequently Asked Questions
What is a dial thermo-hygrometer used for on ships?
A dial thermo-hygrometer measures both air temperature and humidity. It is commonly installed in engine rooms, accommodation areas, cargo holds and stores to monitor environmental conditions and prevent condensation, rust or damage to goods.
Is the thermo-hygrometer powered by batteries?
No. The instrument uses mechanical sensing elements – a bimetallic strip for temperature and a hygroscopic membrane for humidity – so it requires no power supply and will continue to function during blackouts.
What is the accuracy of the temperature and humidity readings?
Typical accuracy is ±1°C for temperature and ±5% RH for relative humidity, which is adequate for marine monitoring applications.
Can this thermo-hygrometer be mounted on a bulkhead?
Yes, the unit features a flanged case with screw holes for quick and secure bulkhead or wall mounting.
