portable digital thermometer
  
 

 

   
  All meters reach the temperature coefficient below 50ppm, which can steady work within the allowable range.
  Patent&Proprietary technology.
  The proprietary semi-conductor sensor technology makes the linearity of the sensor up to 0.1% .
  Custom design a sensor to meet your needs perfectly, quick response.
  Measuring range from -100 to 300 ¡æ
  Wide temperature, big screen LCD
  Low-power consumption, operating current of the whole machine is only 1mA
  The proprietary outer shell
