English user-manual included.

Measuring instrument with a range of -50 ... 150 ° C, designed for temperature monitoring of the three probes.
 
The current value of the temperature with a resolution of 0.1 ° C and channel number is displayed cyclically in an interval of 3 seconds. Unused measuring channels can be switched off in the parameter menu. The user can set six separate alarm thresholds MIN / MAX, two for each channel. After crossing each alarm threshold, an audible alarm and relay output will be activated.
 
In Alarm Settings, you can program the hysteresis for the alarm and the time delay of the alarm. By changing the operating mode of the alarm relay NO / NC, you can connect the device to your alarm system and in addition to the information about the too high temperature or about failure of the temperature sensor, system will detect a power failure. Extreme MIN / MAX temperatures are stored.
 
The user can read them by pressing the INFO button. Menu can be protected by an access code. The meter was designed in an industrial, hermetically sealed IP65 housing to work in difficult conditions.
It is resistant to dirt, high humidity and low temperatures. The meter contains three stainless steel temperature probes with cable length of 2 m. Available in three versions, power supply: 230 VAC, 12 VAC / DC and 24 VAC / DC.
