IoT Wireless Temperature and Relative Humidity Datalogger for External Probe, with Built-in GSM Modem
GSM datalogger is designed to record temperature and humidity from an external probe. In case of exceeded set limits, SMS and JSON messages can be sent via GPRS data connection. Measured values can be sent to the internet storage COMET Cloud, which is complete monitoring, alarm, and analysis system. It is also possible to set the regular sending of JSON messages to COMET Database, the sending interval is adjustable. Alarms are also indicated locally by LED, LCD, and acoustically by built-in beeper.
The recording is performed in non-volatile electronic memory. The data can be transferred to a PC via included USB-C cable. The temperature and humidity probe is not included in delivery, the probe of the appropriate length and design you can choose in optional accessories. The device includes a Traceable calibration certificate with declared metrological traceability of etalons is based on requirements of EN ISO/IEC 17025 standard.
This model measures temperature, relative humidity, and dew point temperature using an outdoor COMET Digi/E series probe. Its response to the temperature or relative humidity jump is significantly faster than by models with internal sensor. This model is often utilized to monitor areas in which only the probe is installed, whereas the main unit is installed elsewhere. When monitoring remote areas, the maximum probe line wire must not exceed 15 m. The Digi/E series probes provide calibrated measurement values. Hence, they may be replaced without having to modify the device setup
