Features

1. refrigeration system: With low noise totally enclosed compressor, air cooled

cooling speed, temperature stability is strong, etc.

2. control system: Latest proprietary software research and development of homemade

temperature control technology, with high standards of Pt100 and all imports

electronic parts, etc.

3. circulating system: Consists of inner and outer loop irfpa outer loop slot can be

constant temperature liquid, can establish the temperature field, also can be used

cold source to guide groove is cooling liquid into closed experimental container cooling

inner loop can make the liquid in the tank temperature was uniform and stable.

4. protection system: Refrigeration is overheated, over-current protection, call control

system has overtemperature alarm, can be set overtemperature alarm temperature

the temperature of the upper and lower limits can cut off the load automatically when

overtemperature, and other functions.

5. High-end LCD control instrument, simple operation, temperature stability is strong

P. I .D can automatically search or artificial adjustment

6. Accurate temperature correction function can reach 0.01 ℃, temperature fluctuation

degree of up to / - 0.02 ℃ ~ / - 0.05 ℃ (depending on the type).

III. Technique Parameter

IV. Operating Steps

1. Slot in liquid medium, medium level cannot under working table 20mm.

2. The selection of liquid medium:

A:When working temperature is below 8 ℃, liquid medium generally choose industrial

alcohol.

B :Working temperature 8 ℃, 80 ℃, the pure water is generally selected liquid medium.

C:Working temperature 80 ℃ to 90 ℃, water and oil mixture is generally selected liquid

medium.

D:Working temperature at 90 ℃ to 100 ℃, generally choose the oil liquid medium.

3. Circulating pump connection:

A:Circulating pump in the connection, connect the outlet and inlet hose.

B :external circulation pump for external loop connection, connect the outlet hose

outside the tank container imports and exports to connect water inlet on the outside

the tank container.

4. plugged in, open the total power switch, then open "power" button and "cycle" button.

(note: "total power switch on the back of the instrument).

5. instrument operation is as follows:

A:Instrument button shows:

SET setting function key shift key ▼ The reduction key ▲ The addend key

B :temperature setting:

Such as working temperature is higher than the environment temperature, according

the set function keys into the temperature set point. Value bottom flashing, press

shift key before at this time the addend, set up your required working temperature

press set again the function keys and save the setting, the measurement is shown in

groove of the temperature of the liquid medium, then into a state of microcomputer

automatic control.

C:Such as working temperature below the environment temperature, open "cooling"

button (note: the above the liquid temperature 40 ) could not be opened, according to ℃

the set function keys into the temperature set point. Value bottom, at this time to press

the shift key and press reduction, set up your required working temperature, press set

again the function keys and save the setting, the measurement is shown in the groove

the temperature of the liquid medium, then into a state of microcomputer automatic

control.

6. temperature and actual temperature measurement, correction:

In normal display mode, long press "set" button for 3 seconds, the display window

shows the password prompt "PA", discharge shows the password value, press the add

key at this time to enter the password "00003", then click on the "set" button, enter

state of internal parameter setting, and then click the "set" key to choose the parameter

to be modified, select the indicator on the window display "Pb", at this time for

temperature correction, such as high temperature and then press the add key, low press

reduction; Then press the "set" button for 3 seconds to exit this state, and

parameter value will be saved automatically. When the measured value reaches

working temperature, it can be stabilized for a period of time before the experiment or

test.

V. Precautions for use

1. Before using slot should be in liquid medium. (note: liquid not contain acid alkali).

2. The total power of the power is to be greater than or equal to the instrument,

power must have a good "grounding" device. Using the voltage will be subject

technical parameter table.

3. Device should be placed in ventilated dry place, back and sides leave obstacles 300

mm distance.

4. After use, all switch off and unplug the power plug.
