Elitech RC-4HC temperature and humidity data logger features a multi-function LCD alarm indicator, a replaceable battery with a buzzer alarm. A reason why it satisfies the dynamic and growing demand for cost-effective temperature data logger in cold chain supply.With Elitech temperature data logger, you don’t require additional software to access information. Users can export data in PDF or Excel via Elitech data management software. Features: Easy operation: When connected to a computer, the software will read data automatically, and form reports. LCD screen displays the temperature, time, over-temperature alarm, temperature upper/lower limit, and Max/Min temperature. Two sensors: one internal sensor and one external sensor. Used to record temperature data over a long period of time. LCD displays data and settings. Above one-year battery life. 16000 data recording capacity. Data management software & USB cable included for working with PC easily. Specifications: Humidity Accuracy ±3%RH (25℃,20~90%RH), Others,±5%RH Humidity Measuring Range 0~99%RH Resolution Temperature 0.1℃; Humidity 0.1%RH Temperature Measuring Range -30℃~+60℃; External sensor(cable length 1.1m): -40℃~+85℃ Temperature Accuracy -30℃~+60℃, ±0.6℃; Others, ±1.2℃ Ambient Temperature -30℃~+60℃; in the low-temperature environment, LCD displays slowly, while it has not an impact on the normal measuring or recording. Once the temperature recovers, it could display normally.
