For the control of temperature and humidity with indication of dew point, max./ min. function, average values, alarm at freely adjustable temperature and humidity values (upper/lower limit), data logger with a capacity up to 50.000 measured values, recallable via display or PC-USB interface. Connection of up to 8 wireless outdoor transmitters.
Warning: Last items in stock!
This device allows you to make detailed recordings of the temperature and humidity and to actively monitor them. Recorded data can be transferred to a computer using a USB transceiver for easy analysis. The supplied software can also be used for managing the logger and can be used purely as windows service to provide datasets to your own software application. The logger is able to use up to eight outdoor transmitters.
Areas of application:
DCF RADIO CONTROLLED TIME RECEPTION
Note for Radio Controlled Time DCF:
The base for the radio controlled time is a Caesium Atomic Clock operated by the Physikalisch Technische Bundesanstalt Braunschweig which has a time deviation of less than one second in one million years. The time is coded and transmitted from Mainflingen near Frankfurt via frequency signal DCF-77 (77.5 kHz) and has a transmitting range of approximately 1500 km. Your Logger receives this signal and converts it to show the precise time in summer or wintertime. The quality of the reception depends greatly on the geographic location. In normal cases, there should be no reception problems within a 1,500 km radius around Frankfurt.
Recommended distance to any interfering sources like computer monitors or TV sets is a minimum of 1.5 - 2 metres.
Within ferro-concrete rooms (basements, superstructures), the received signal is naturally weakened. In extreme cases, please place the unit close to a window and/or point its front or back towards the Frankfurt transmitter.
During night-time, the atmospheric disturbances are usually less severe and reception is possible in most cases. A single daily reception is adequate to keep the accuracy deviation below 1 second.

Note: If you select Accredited Calibration Certificate (IPAC) when purchasing this product, click the Product Customization TAB and fill in the second field (TEXT - Required temperature calibration points.) with the respective required points or simply attach a copy of a calibration certificate.
An IP rating, also known as "International Protection" or "Ingress Protection" rating, is a value assigned to a product that determines its susceptibility to ingress from solids and liquids. The first numeric digit relates to the level of protection against solid objects, and the second numeric digit indicates the level of protection against liquid ingress. Click for a table of IP Rating values.
Table of IP rating values
IP65 - No ingress of dust (6); Protection from water ingress: Low pressure jets of water (5).
