1、 Purpose
The wireless transmission technology of wireless large screen melting thermometer is that the temperature value measured by the portable thermometer is transmitted to the wall mounted large screen display synchronously and accurately through the wireless transmission technology, which saves the fetters of the connection of the wall mounted large screen thermometer, and improves the anti-interference ability of the instrument.
2、 Features
The wireless large screen melting thermometer has the dual characteristics of the flexibility of the portable thermometer and the long-distance visibility of the wall mounted large screen instrument, which saves the fetters of the connection between the test gun and the large screen display.
The instrument is composed of portable melting thermometer with wireless transmitting function and large screen display with wireless receiving function (displayed by 5-inch digital tube: word height: 128mm). At the end of temperature measurement, it has the functions of synchronous light indication, bell sound prompt and automatic holding of temperature measured value. It also has alarm functions such as disconnection of coupling, over range and under voltage of power supply.
The instrument adopts imported professional data transmission module to ensure the high reliability of wireless transmission of measurement data.
This instrument can be equipped with five kinds of thermocouples. Because of the new anti-interference measures, the instrument has good anti-interference ability. When the medium frequency furnace is electrified, the temperature can be measured in the furnace without power off.
The instrument can store 1000 sets of historical data and has the function of printing.
