ZNHW smart thermostat heating units Introduction ZNHW-II heating mantle

ZNHW type heating units with E-glass fiber insulation, will Cr20Ni80 alloy wire spring device in which, with silicate cotton hemispherical shape by vacuum thermal insulation body, a one-time injection molding shell, cover with electrostatic spray technology, the use of spherical heating, the container can heat an area of more than 60%. Temperature control unit uses a computer chip to do, using multiple digital filter circuit, fuzzy PID control algorithm, with high accuracy, small red temperature, touch touch operation, dual display, internal and external thermocouple, controllable silicon control output,160-240V wide voltage power supply, and a burnout protection with fast heating, high temperature, easy to operate, durable features, is doing precise temperature control heating ideal test instrument.

Use ZNHW-II heating mantle

1 Insert ~ 220V power supply, turn on the power switch, the display shows "K", set the window displays " 400" character, based appliance equipped with K -type thermocouple , temperature control up to 400 °C, 3 seconds later, the display shows room temperature , set temperature settings window displays the last value .

2 one-touch operation, press the set plus , to quickly set the desired heating temperature such as : 100 °C, heating said green light , green light means stop off , microcomputer will be determined according to the set temperature and current temperature to increase the size of the heat , to ensure that no temperature overshoot a warming place , and keep the balance for heat settings and display value ± 1 °C temperature difference under the heating process easy to complete .

3 electric sets the lower left with a rubber stopper to protect the external thermocouple sockets not rust and corrosion inside with a turn , then unplug the probe is disconnected , the machine stopped working. If this plug with the external thermocouple should unplug the save, the external thermocouple plug into the socket and lock nut , and then the stainless steel probe into the solution for temperature control heating .

4 The electrical burnout protection function, when the thermocouple connection is bad, the display shows " 1" or "hhhh" window 100 on , the green light is off , stop heating appliances to be checked before use

FAQ

1. Liquid spill into the sleeve, please shut off the power, the electric heating set put in ventilated place, can be used only to stay dry, and in order to avoid leakage risk or electric short circuit occurred.

2. Long-term need not when, please put in dry non-corrosive gases electric jacket.

3. Please don't empty set of heating or dry.

4. Environmental relative humidity is too large, there may be a induction through the insulation layer to the shell, please service grounding line, in order to avoid leakage, and pay attention to ventilation.
