Temperature and humidity data logger with LCD display

DLHT is a temperature and humidity datalogger equipped with a graphical and alphanumeric LCD display and a small keyboard to program missions and access the data. The data logger may be programmed from a PC, using its software by means of a USB cable connection to the device. This device is equipped with audio and visual alarms (LEDs) that indicate when the temperature has exceeded the pre-set minimum and maximum thresholds. A third led warns you when the batteries need to be replaced. DLHT operates using replaceable batteries and its low power consumption means they do not have to be replaced very frequently.

The data logger can be supplied with verification of calibration certificate with Accredia (Italian reference center, NIST equivalent) traceability.

The LCD display and the USB interface make this device an autonomous product, and does not require the use of a PC (to which you can nevertheless always save and edit data). Used with the E-Log Alarm software it gives you the possibility to get instant email alarms (a PC with internet connection needed).
