YH-ZK2 ZK4 ZK6 new digital constant temperature water bath

YH-ZK2 ZK4 ZK6 new digital constant temperature water bath

The digital constant temperature water bath is a multifunctional constant temperature water bath controlled by microcomputer technology, widely used in fields such as medicine, biochemistry, light industry, and scientific research.

YH-ZK2 ZK4 ZK6 new digital constant temperature water bathProduct Features:

1、 High brightness digital display, clear parameter settings, beautiful and elegant appearance;

2、 Controlled by microprocessor, with good temperature control linearity and small fluctuations；

3、 Using external heating instead of traditional internal heating tube heating, internal heatingbuilt-inovertemperatureSensor, dry burningAuto power-off, safe and reliable.

4. External heating of liquid temperature is more uniform, safer, and more reliable, and can also avoid situations like long-term use of built-in heating tubes, where scale forms on the surface of the heating tube and the heating tube melts and leaks electricity.

5The shell and insulation board are both high-strengthPC (Polycarbon) material is made by one-time injection molding, which is corrosion resistant and anti-aging, and the liner is made of 304 stainless steel by stamping.

Instrument operationInstructions for Use

1Power on the temperature controller and display the temperature control area on the window,2After seconds, it will enter the normal display state.

2Temperature setting: PressSETPress the key to enter the temperature setting state, and a prompt will appear on the upper row of the display window“SP”The lower row displays the temperature setting value, which can be changed to the desired temperature value by pressing the increase and decrease keys, and then pressingSETPress the key to exit this setting state, and the modified setting values will be automatically saved. At this point, the instrument is working normally.

3Normal operation does not require changing internal parameters. If you need to change internal parameters, pressSETkey3After a few seconds, enter the internal parameter area and press each buttonSETKey change parameter indicator code.

4Precautions

（1）instrumentWhen working, someone needs to be on duty, and the security check and calibration cycle of this instrument is six months.

（2）Please do not work in areas with flammable, explosive, or corrosive gases.

（3）instrument displayHHHTo measure values that exceed the limit on the instrumentShort circuit in the process or sensor, instrument displayLLLThe sensor is not installed or the sensor is disconnected.

（4）There is a water level indicator inside the tank, and only an external temperature sensor is used for this water bath. Please make sure that the water level exceeds the water level indicator line inside the tank. If the liquid level in the tank is low, it will cause abnormal temperature fluctuations in the liquid inside the tank.

During normal operation, the upper row displays the measured temperature value and the lower row displays the set temperature value. When entering the internal parameters, the upper row displays the parameter code and the lower row displays the parameters.
