ZNHW-I intelligent constant temperature controller - ZNHW-I

ZNHW-I intelligent constant temperature controller

Product Specification

ZNHW-I type intelligent constant temperature controller adopts computer wafer as main control unit to control temperature .Using multiple digital filter circuit , fuzzy PID control algorithm ,with double screens digital display , self adjustment function ,high precision ,small temperature impact ,one-button tick operating , controlled silicon manage the output ,160-240V wide voltage power supply and with thermocouple broken protection function. Shell is made by one-time injection molding process.With features of beautiful appearance,easy operating, lightweight and flexible,it is the ideal experimental equipment to control the electric furnace and electric heating mantle to do the precise temperature control heating test.

Usage

1. Connect to the AV 220 power source ,open the power switch ,PV display window will display “K” ,the setting window display “400”, fit the equipment with K type thermocouple , the maximum control temperature 400 °C , 3 seconds later , PV display window will show the room temperature ,the SV setting window will display last setting temperature value .

2.Insert the power line of the controlled heater into the output plug of the temperature controller.

3. Put the temperature sensor into te controlled liquid or container.

4.Single key operation ,keep pressing the button so as to set the required temperature swiftly,such as 100°C.The green light on express heating and the green light off express stoping.The microcomputer will confirm the quantity of heat according to the temperature difference between the setting temperature and current temperature to make sure that there is no temperature error and warming can be made in one time,at the same time to maintain the radiation balance with a tolerance of ±1°C between the setting data and real-time data,making it easy to finish the heating procedure .

5.With thermocouple broken protection function,when the thermocouple is not connected well or switch off , the display window will show “hhhh” ,when green light is off , instrument will stop heating , please check it before using.
