The DAQ LogBox-RHT-LCD is dual channel data loggers with built-in temperature and relative humidity sensors. This DAQ LogBox uses a high quality industrial grade humidity sensor for accurate and reliable operation in applications such as transportation, food and goods storage, process auditing, pharmaceutical, HVAC and others.
They can be easily programmed and set via a handy infrared IR-LINK 3 interface connected to a USB port under Windows® software or with a PalmOS compatible PDA IrDA interface. LogChart II software allows for logger configuration, recorded data retrieval, plotting, historical analysis and it exports data to spread sheets.
In the LogBox-RHT-LCD the temperature and humidity values are shown in the digital display. You can also check on the display the Minimum and maximum recorded values.
