A small meter and recorder of microclimatic conditions. Designed for documenting parameters in warehouses, transport and industrial production. Particularly useful in the pharmaceutical and food industry, wherever supervision of goods sensitive to temperature and humidity is required.
Suitable for providing a supply cold-chain (a temperature-controlled supply chain), monitoring archives, controlling conditions in laboratories, industry and offices.
The battery-powered sensor can operate autonomously for a long time. The smartphone application provides wireless reading of current data and registered records. The device can work as part of the STORE-LOGGER-B measuring system.Measurement:
The LB-518 BLE-LOGGER thermohygrometer is a wireless relative humidity and temperature mini recorder. The recorder is equipped with a BLE wireless radio interface. It is powered by an internal exchangeable 3 V battery, CR2450 type. For the temperature and humidity measurement, the LB-518 BLE-LOGGER thermohygrometer uses an integrated, high-quality humidity and temperature sensor.
The LB-518 BLE-LOGGER thermohygrometer features an extensive memory for storage of 15,000 entries of temperature and humidity measurement results. The data are stored in the memory and “overwritten”, which means that when the memory is full, the oldest recordings are deleted. The recorder allows threshold temperature and humidity values to be set with alarm signalling when the values are breached.
In typical applications the LB-518 BLE-LOGGER thermohygrometer performs measurements and carries out recording in the memory over the user-defined time (typically, every 1 minute, optionally, every 5, 15, 30 or 60 minutes).
Over a set time, the recorder switches on the BLE interface and establishes connection with an external receiver; in typical applications the receiver is any smartphone or tablet with Android 5.0 (or later). The data sent by the LB-518 BLE-LOGGER thermohygrometer are received via Bluetooth 4.0 interface of a smartphone with a suitable application installed, which reads information about the current temperature and relative humidity measurement, as well as information about the technical condition of the recorder (identification data, battery consumption). On request, the collected archived temperature and humidity measurement results may be read-out from the recorder’s memory.
For a read-out of the current and the memory-recorded data from the LB-518 BLE-LOGGER thermohygrometer, special applications for Android are available:
The LB-518 BLE-LOGGER thermohygrometer should not be operated in the vicinity of metal surfaces or inside metal containers, as this may considerably limit the communication range with the receiver.
The LB-518 BLE-LOGGER thermohygrometer is designed for controlling and documenting the course of technological processes in production facilities and warehouses — especially in pharmaceutical, medical and food industries, where the supervision of goods subject to temperature and humidity is required. It is especially useful in meeting the requirements for ISO, HACCP and GMP production quality control in food and pharmaceutical industries.It may be used for temperature and humidity control in vehicles, packages, pharmacies, warehouses and State Sanitary Inspection facilities — e.g. during transportation and storage of vaccines and medicines.
