Description of the recorder
The LB-516A electronic thermohygrometer is a miniature temperature and humidity recorder, powered by a built-in long-lasting lithium battery. For measurement the recorder uses a built-in temperature sensor and humidity capacitive sensor.
The recorder is equipped with a large memory for storing measurement results, which — for example, with the recording interval set to 20 minutes for the LB-516AT temperature recorder — is sufficient to record measurement entries for more than a one year recording session. It is possible to store in the memory by “overwriting” (when the memory is full, the oldest recordings are deleted). The recording is commenced when the key on the recorder’s housing is pressed.
The recorder also allows temperature and humidity threshold values (lower and upper) to be set that when breached during a recording sessionLB-516A trigger an alarm (when the key is pressed) with a lit colour LED diode.
The LB-516A thermohygrometer is a wireless device and fully automatic (it does not require interaction with a computer while recording). The recorder is programmed (e.g. setting the interval, method for starting the recording), and, subsequently, the read-out is performed and the stored data are printed out with the use of a PC, after connection to a USB port. The LB-516 temperature and humidity recorder does not require any additional interface — it may be connected directly to the USB port of a computer with a USB AB type cable.
For interaction between the LB-516A recorder and a PC, the specialized LOGGER application is used. This application enables the full service of the recorder: preparation and end of recording, read-out of the recorded temperature and humidity, presentation of the recorded data in the form of a table, chart and histogram, recording memory clearing, setting temperature and humidity alarm thresholds, introduction of any descriptive text into the instrument’s memory.
Each temperature and humidity recorder features a permanently saved serial number, providing unequivocal identification and the possibility of inputting the user’s name and mission name (the individual name of a given recording cycle).
Each thermohygrometer may feature an individual calibration certificate issued by the LAB-EL Calibration Laboratory.
The LB-516A recorder is designed for controlling and documenting the course of technological processes in production facilities — especially in medical and food industries. It may be used to record climate parameters during the transportation of goods subject to temperature (temperature monitoring during transportation). The thermohygrometer may be placed in packages with the transported goods. The recorder is especially useful for meeting the requirements of production quality (HACCP) and transportation control.
