The DCMRHT101 2-channel miniature data logger is a small battery-operated data logger for measuring temperatures and humidity. The high measuring and operating temperature range of -40 °C to +80 °C and the integrated semiconductor sensors enable a wide variety of applications.
The non-volatile internal memory (for storing up to 500,00 measured values) guarantees a high level of data security, even if the battery should cease to function.
The data logger can be easily set, started and stopped using a PC. The comprehensive and user-friendly software automatically recognizes the connected data logger and allows easy evaluation of the measurement data.
