FAQs
The temperature sensor can measure temperatures ranging from -30° to 70°C (-22° to 158°F).
The accuracy varies depending on the temperature range:
±1.0°C from -30° to -5°C (±1.8°F from -22° to 23°F)
±0.5°C from -5° to 50°C (±0.9°F from 23° to 122°F)
±1.0°C from 50° to 70°C (±1.8°F from 122° to 158°F)
The resolution of the temperature sensor is 0.04°C (0.072°F).
The temperature sensor has a drift of less than 0.01°C per year (0.018°F per year).
The typical response time to reach 90% in open air moving at 1 m/s is 6 minutes.
The logger operates within a temperature range of -30° to 70°C (-22° to 158°F).
The logger has a transmission range of approximately 30.5 meters (100 feet) line-of-sight.
The logger uses Bluetooth Low Energy (Bluetooth Smart) for wireless data transmission.
The logging rate can be set from 1 second to 18 hours.
The time accuracy is ±1 minute per month at 25°C (77°F).
The logger uses a CR2450 3V lithium battery, which is not replaceable.
The battery life is typically 1 year with a logging interval of 1 minute and Bluetooth Always On enabled. It can last up to 2 years with Bluetooth Always On disabled, depending on usage patterns.
The logger can store up to 30,000 measurements.
Downloading the full memory typically takes approximately 30 seconds, although it may take longer if the device is farther from the logger.
The dimensions are 6.9 x 4.5 x 1.1 cm (2.71 x 1.76 x 0.42 inches), and it weighs 25.5 g (0.90 oz).
The logger has an IP67 environmental rating, meaning it is dust-tight and can withstand immersion in water up to 1 meter for 30 minutes.
