Relative Humidity

These data loggers all have internal temperature and relative humidity sensors. Both the SL7000 and the SL702-128K data loggers also have the ability to add external temperature and relative humidity sensors allowing two locations to monitored at the same time.



SL54TH

Our lowest cost temperature and relative humidity data logger recording from -40°C to +85°C and 0 to 100%RH. Accuracy ±0.5°C and 5%RH
Lowest Cost RH Logger

SL54TH-A

Temperature & relative humidity data logger with an improved accuracy over the standard SL54TH of ±2%RH. Still one of the lowest cost RH loggers.
Improved RH Accuracy

SL54M

Our lowest cost temperature and relative humidity data logger recording from -10°C to +50°C and 0 to 100%RH. Accuracy ±0.5°C and 5%RH
Flexible Mounting Options

SL54M-A

Our lowest cost temperature and relative humidity data logger recording from -10°C to +50°C and 0 to 100%RH. Accuracy ±0.5°C and 2%RH
Improved Accuracy
