[Features] · Easier management of temperature and humidity data using an SD card. Omron high precision thermo-humidity loggers use sensors with the highest precision in their class and for the first time include an SD card data collection system. · This enables precise control of temperature and humidity at multiple points along the manufacturing line and more efficient collection of data. · The logger has alarm output providing immediate alerts when trouble occurs, helping meet strict quality control standards. · Data can be collected only when needed by simply inserting an SD card. · Thermo-humidity logger memory can store up to approximately 8,500 pieces of data. · Measurement data is transferred/stored in CSV format on the SD card. · Data continues to be recorded in built-in memory even while data is being collected onto SD card. · Store data up to maximum memory capacity by keeping SD card continually inserted (approximately 17 million pieces of data per 1GB. Store up to five years of data when measurements are made every 10 seconds) · Compact body with useful features. · Remarkably high measurement accuracy. · Precision measurement ensures a temperature resolution of 0.1°C and humidity accuracy of ±2.5%. Enables more precise control of temperature and humidity, which contributes to improvement in product quality. · Runs for approximately 1 year on two commercially available AAA batteries. · With built-in backup function, recorded data won't be lost even if batteries run out.
