AVT5389 C

We present an electronic thermometer measuring temperature in four distant places. The measurement result is shown on a four-position, large and legible LED display. Temperature sensors DS1820 were used as temperature sensors. Connecting each of them to the thermometer requires only two wires, which makes the entire installation easy and convenient to set up, for example, at home.

The device is especially recommended for simultaneous temperature control in many places

Selected parameters:

• number of temperature sensors 1-4
• automatic (every 3 seconds) or manual switching of measuring channels
• measured temperatures in the range -55 to + 125 ° C
• presentation of results - a four-digit LED display and LED diodes indicating the active measurement path
• automatic recognition and cooperation with sensors type DS1820, DS18S20, DS18B20
• measuring accuracy (DS18B20): ± 0.5 ° C (-10 ° C ... + 85 ° C), ± 2 ° C (-55 ° C ... + 125 ° C)
• reading resolution (DS18B20): 0.1 ° C in the entire measuring range
• the system does not require calibration
