Thermo-Hygrometer Data Logger Model 1246

The Thermo-Hygrometer Data Logger Model 1246 is a portable, compact digital meter designed for simplicity and one-hand operation. The main advantage of the logger is its ability to perform a variety of recording tasks with easy and intuitive setup from a computer using supplied DataView® software. The meter uses an NTC as the temperature sensor, providing excellent response time to changes in temperature, good repeatability and accurate readings. The Model 1246 also utilizes a thin film polymer capacitive type relative humidity sensor as hygrometer sensor, offering excellent recovery from 100% moisture, and fast response time and durability.
