Far-infrared furnace thermostat timer COD digestion 

 Introduction 

 COD of the far-infrared furnace thermostat timer digestion, is designed for the determination of environmental monitoring indicators COD designed a new generation of digestion equipment. It uses far-infrared heating element for heaters, the use of temperature controller to maintain a constant temperature during digestion, and with time the timer to automatically control the digestion time required is a semi-automatic, dedicated digestion energy-saving equipment.

 Use 
 (A) the temperature setting (the factory when the temperature is set up, it is best not to move) 
 Furnace in the digestion of the right of the two instruments, one for temperature control below. Open the protective plexiglass cover the surface of the instrument can be directly used to adjust the knob to set the desired temperature, the temperature is generally set to 225 ℃, and then covered with protective cover, the temperature setting is completed. Temperature control device for the heating state the green light, red light as a separate constant temperature. 
 (B) of the regular time setting (the factory has set up regular time, it is best not to move) 
 Digestion furnace in the right two instruments, the top one for a regular meter. Open the plexiglass protective cover, below a row of the instrument (five) small window, a small window each have a small button on the bottom, a small window to set the value. When adjusted values for 02h00, 2 hours is the countdown timer. Then covered with protective cover, timing set is completed. 
 (C) power to use 
 1, plug in the power plug before you check the power switch, timer switch, so that they are in the "off" state. 
 2, plug in the power plug, it will power switch "on" state, so that digestion furnace heating, when the furnace reaches temperature digestion state, put the bottle heated digestion. 
 3, when the liquid just begins to boil digestion when the time switch to "on" state, the countdown timer starts 2 hours. When the timer expires, the timer display value is 00.00, the timer will automatically turn off the heater temperature controller and power supply, digestion is completed. 
 4, if you do not need to continue with the next batch of sample digestion, then set the two switches are hit the "off" state, you can disconnect the power plug. If you have to continue to the next batch of sample digestion, only make the next batch of bottles into the oven digestion hole will drop timer switch to "off state", until the next batch of samples has just begun boiling, time and then switch to "on" state can be.
