L702

The Simple Logger® II Model L702 is a two channel Temperature/Humidity recording device powered by alkaline batteries. It is capable of measuring temperatures from 14 to 122°F (-10 to 50°C) and 5 to 85% RH with resolutions of 0.1 degree and 0.1% RH.

Model L702 stores measurements at user programmable rates of once every 5 seconds to 1 every day. Up to 240,000 measurements can be stored for a period of 45 days or more.

The L702 incorporates a unique capacitive sensor element for measuring relative humidity while temperature is measured by a band-gap sensor. CMOSens® technology guarantees excellent reliability and long term stability with high accuracy.

Analog information on the input is sampled and converted to a digital signal with up to 14 bit resolution. An optically isolated Universal Serial Bus (USB) port provides for the transfer of data from the instrument’s internal memory to the computer for analysis.
