Data Logger Comet U4130 – Temperature, Humidity and Pressure Data Logger with Built-in Sensors

• A solution for every need, every budget – economy and premium dataloggers
• High quality, accurate and stable sensors
• Built-in battery operated
• Built-in printer

Datalogger is designed to record temperature, humidity, and atmospheric pressure. The recording is performed in non-volatile electronic memory. The data can be transferred to a PC via USB-C. In case of exceeded set limits alarms are indicated by LED, LCD, and acoustically by built-in beeper. Recorder includes a Traceable calibration certificate with declared metrological traceability of etalons is based on requirements of EN ISO/IEC 17025 standard.

Compact thermometer – hygrometer – pressure gauge

This model is designed to measure temperature, relative humidity, dew-point temperature, and barometric pressure by internal sensors. Barometric pressure can be measured as absolute or recalculated to sea level. No additional probes or sensors can be connected. It is characterized by a simple and compact design and a relatively long response in the measured quantities, compare to the model with external probes. The sensors are located under the grid on the front and side of the unit. The device is suitable for measuring in places where there is no rapid change in temperature or relative humidity, and there is no condensation of water vapours.

The device is placed directly in the measured space. The battery in the device cannot be charged. It is recommended to calibrate this device in the laboratory with the unscrewed bottom lid of the box to allow the air to flow from the back of the electronics. When airflow in the range of 0.5 – 1 m/s perform reading after about 4 hours.

The closed device reaches a difference of approximately 2 %RH when inserted in the humidity chamber, then dramatically slows down. Precise reading takes many times longer time than with the open rear lid.
