1、 Structure and working principle:

HH-S8Digital constant temperature oil bath potAlso known as a porous constant temperature oil bath pot, the outer shell is formed by stamping, folding, and welding steel plates. The surface of the shell is coated with high-strength electrostatic spraying, resulting in a smooth and firm paint film. A stainless steel tubular heater is horizontally placed inside the tank, and a perforated stainless steel shelf is placed inside the tank. The lid is equipped with combination rings of different diameters, which can adapt to flasks of different diameters. On the right side of the oil bath pot is an electrical box, and the front panel of the electrical box is equipped with temperature control instruments and power switches. There are electric heating tubes and sensors inside the electrical box. The temperature control system adopts high-quality electronic components, with sensitive temperature control, reliable performance, and easy use. Its working principle:PT100The sensor converts the temperature inside the tank into a resistance value, and after amplification and comparison by an integrated amplifier, outputs a control signal to effectively control the average heating power of the electric heating tube, keeping the oil inside the tank at a constant temperature. This series of products has the dual function of water and oil, which can be used as both a water bath and an oil bath, with high cost-effectiveness.

HH-S8Digital constant temperature oil bath pot in its original formHH-SMade on the basis of changes,The internal structure is8This oil bath pot has the characteristics of a six hole water bath pot with one hole, the same chamber, and one temperature. It also has the constant temperature range of an oil bath pot. The same series of digital constant temperature oil bath pots have a single hole type,Double hole type,Four hole type,Eight hole digital constant temperature oil bath pot,If non-standard parameters and models are required,Please call to inquire about customization!

2、 Purpose:

HH-S8Digital constant temperature oil bath pot Suitable for various reagent distillation, drying, concentration, and constant temperature heating in medical institutions, colleges, research departments, and industrial and mining enterprise laboratories.

3、 Technical parameters:

4、 Installation and use:
4.1 Before installing the equipment, the oil bath pot should be placed on a flat workbench for visual inspection: the appearance should be undamaged, the instrument appearance should be intact, the wire insulation should be good, the plug should be intact, and the power switch should be flexible. Each device's power cord is connected to a single-phase three pole plug, where the plugzuiThe electrode above is the grounding electrode, and users must use a single-phase three pole power socket. The grounding electrode of the power socket should have a reliable ground wire.
4.2 Before powering on, inject oil into the tank of the oil bath pot. After filling, there should be no oil leakage, and the liquid level should be kept at a distance from the upper opening2—4cmThe distance should be set to prevent water from overflowing into the electrical box and damaging the components.

Heating oil selection method:

★ Operating temperature ＜95℃ water

★ Operating temperature ＜170℃201#methyl-silicone oil

★ Operating temperature ＜250℃ Phenyl Silicone Oil

★ Operating temperature ＜300℃350#High temperature thermal oil

4.3Setting and use of digital temperature control instruments:
Turn on the power switch, the temperature controller lights up, click the function buttonsetThe upper row displays the set temperature, while the lower row displays itspThen click △ or ▽ to select the working temperature, set it up, and click the function key againsetEnter the timing setting state, click △ or ▽ to select the constant temperature timing time. If no timing is required, set the time to0Click the function key againsetExiting the setting state, the temperature controller will run according to the set program. In the absence of a set timer state, the upper row displays the actual oil temperature inside the pot, and the lower row displays the set temperature. If a timer time is set, the upper row displays the actual oil temperature inside the pot, and the lower row displays the timer time. The timer counting method is based on the countdown method. When the scheduled time is up, there will be an audible alarm output.

Experiment completed, adjust the temperature to0Then turn off the power. (When not in use for a long time, please pour out all the oil in the pot and do a good job of maintenance)

5、 Precautions for use:
1All technical indicators of this series of products have undergone actual operation inspection before leaving the factory. If the user needs to use a self provided thermometer (with certain accuracy) for measurement due to process requirements, the user's thermometer shall prevail. If there is a difference between the displayed value of the temperature control instrument and the thermometer, the user can adjust the internal parameters of the temperature control instrument slightly to meet the process requirements.
2When using an oil bath pot, it is necessary to add water first and then turn on the electricity. Dry burning is strictly prohibited.
3、 When using an oil bath pot, reliable grounding is necessary to ensure safe use.
4If the oil level is lower than the electric heating tube, it is not allowed to use it with electricity to prevent the electric heating tube from bursting and being damaged.
5、 The oil level should not be too high to avoid overflowing into the electrical box and damaging components.
6Regularly check whether the screws of each contact are loose, and if they are loose, tighten them to maintain good contact of each electrical contact.

7Please read this manual before turning on the power when using.

8Oil should not be too much to avoid experimental failure caused by oil spillage.

9Please wear protective gloves during operation to avoid burns.
10If the oil bath pot experiences abnormal operation, it should be inspected and repaired in a timely manner. If the fault cannot be accurately determined, the company's technical department can be contacted.

Maintenance method: Three guarantees for one year,Lifetime maintenance.
