Also known as super constant temperature water bath, circulating constant temperature water bath, super constant temperature water bath) is an updated product of super constant temperature water bath. This instrument has a dual function of internal and external circulation, greatly improving the uneven water temperature at various points in the water bath box in the past. At the same time, an external circulation interface is added, which can be connected to experimental equipment outside the instrument, such as a reaction kettle; It has the advantages of high temperature control accuracy, strong corrosion resistance, compact structure, beautiful appearance, energy saving, and long service life. Precision products suitable for constant temperature testing experiments or auxiliary heating in experimental science fields such as biology, physics, plants, chemical engineering, medicine, and environmental protection.

2、 501 Digital Display Super Constant Temperature Water Bath (Tank) Structure:

The inner liner of the 501 digital display super constant temperature water bath (tank) is manufactured using imported stainless steel plate and advanced technology. The outer shell is made of metal plate, and the control box is directly installed on the water tank. There are two inlet and outlet nozzles for the condensate water pipe next to it. The water tank uses imported high-quality water pumps as circulating power, solving the problem of uneven temperature water and achieving high requirements for temperature control accuracy and water uniformity of the instrument.

3、 501 Digital Display Super Constant Temperature Water Bath (Tank) Features:

1. Added circulation pump, improved consistency and accuracy of working temperature.

2. Intelligent temperature control instruments make instrument heating and constant temperature more stable.

3. There are two methods: internal circulation and external circulation, and users can make requirements during procurement according to their own needs.

5. Heating power 800w

6. Water pump flow rate: ≥ 4L/min, power 40w

7. Total power consumption: ≤ 1.2KW

8. Working size: 350 × two hundred and eighty × 180mm

5、 501 Digital Display Super Constant Temperature Water Bath (Tank) Usage:

1. This instrument uses a 220V AC power supply, and the power socket should be a three hole safety socket. It must be properly grounded and the grounding wire should not be connected to the gas pipe.

2. Please ensure that the rated current of the power socket is not less than 6A before use.

3. When adding water, please note that the distance from the upper cover plate is not less than 8cm (for adding water to the super constant temperature water bath). Drinking water must be used, preferably distilled water; Do not use hard water such as well water, river water, spring water, etc. to prevent the heating tube from producing scale and cracking, which may affect the sensitivity of the constant temperature.

4. Connect the power, turn on the power switch, turn on the circulating water pump, and then set the required temperature. The machine will work normally.

5. If you need to quickly reduce the studio temperature, please adjust the digital temperature setting index; Alternatively, either end of the external latex tube can be connected to an ice water or tap water nozzle, while the other end can be connected to a water tank with a latex tube for circulating cooling. The water in the tank will quickly cool down.

6、 501 Digital Display Super Constant Temperature Water Bath (Tank) Precautions:

Instructions for using super constant temperature water bath:

Before use, connect the water pipes at the inlet and outlet, and add water according to the required capacity to shorten the heating time. (Pay attention not to add too much water to prevent water from overflowing outside the pot when boiling, and ensure that the amount of water in the pot is not less than the minimum water sieve, that is, the electric heating tube in the pot cannot be exposed to the water surface. This is to avoid burning the electric heating tube and causing water leakage.). Connect the power, turn on the power switch, and the indicator light will be on.

1、 Operating instructions

1. Set temperature: Press the SET key to set the temperature control point. Press the SET key once, and the character on the digital tube in the lower row of the instrument will start flashing, indicating that the instrument has entered the set state. Press the △ key to increase the set value, and press the ▽ key to decrease the set value. Long press the △ key or ▽ key to quickly change the data. Press the SET key again, and the instrument will return to normal working state. After setting the temperature, the instrument will return to normal working state.

2. Internal function parameter setting:

Press the SET button for 3 seconds to enter the internal parameter setting state of the instrument. In the future, every press

The following parameters in the table appear sequentially in the lower row of the instrument panel with one set key:

Scope of code parameter meaning description

H2.0 Over temperature Alarm Deviation Value When the temperature exceeds the set value plus the deviation value, an alarm will be generated at 0-100 ℃

The proportional heating range of P3.0 heating control is intermittent, and if P=0, it is a positional control. 0-9.9℃

I12 integral time constant eliminates static errors, parameters related to insulation performance 1-99 seconds

D20 differential time constant presetting ability, parameters related to power margin 0-99 seconds

T60 proportional control action cycle control heating and stop heating time plus 2-99 seconds

C0.0 sensor error correction is used to correct measurement errors generated by sensors -4.9-4.9

E0.0 proportional band offset is used to prevent temperature overshoot caused by instrument cold start, ranging from 0.0 to 5.0

LC0 parameter lock LC0 is unlocking, LC1 is locking inner layer parameter 0 or 1

Note: After setting the inner parameters, press the SET key for 3 seconds to save the modified parameters and exit the setting state.

3. Main parameter description

P: It is a proportional parameter, that is, a proportional control value. The instrument is centered around the set value and the P-value is distributed on both sides of the set point. Within the P-value range, the instrument dynamically controls the temperature.

T: To control the temperature, the instrument automatically adjusts the heating and idle time within one cycle of the heating output cycle, which is the working cycle of the heating action. A small T value has a good control effect, but heating with a too small T value will reduce its service life due to frequent operation. The general T-value is set at 3-60 seconds.

E: When P=0, E is an advance control parameter. To reduce temperature overshoot, the instrument will cut off the heating output in advance when controlling the heating output. The output (heating) does not act within the set value and advance range, which can prevent temperature overshoot. When P is not equal to 0, the instrument dynamically controls the temperature using intelligent PID working mode. When P is not equal to 0, the E parameter is proportional with offset.

3. Error correction: When confirming that the displayed value on the instrument is not the correct measurement value, the displayed value can be corrected. Press the SET button for 3 seconds to enter the instrument panel’s inner menu, the first one to appear and flash
