1、 Overview

This product is suitable for liquid heating in laboratories of colleges and universities, petroleum, chemical industry, medicine, environmental protection and other industries. It uses high temperature resistant alkali free glass fiber as insulation material, seals the resistance wire of nickel soldering material in the insulating layer, and then weaves hemispherical internal heating heater, This heater has the advantages of large heating area, fast heating, no open fire, uniform heating, light, safe and energy saving, and not easy to damage glass. It is the most ideal heating equipment for various laboratories and fine chemical units

2、 Technical parameters

Rated voltage: 220 V ± 10%

Rated frequency: 50 Hz ± 2 Hz

Temperature range: ambient temperature + 30 ℃ - 380 ℃

Temperature control accuracy: ± 1 ℃

Working mode: continuous mixing mode -- stepless speed regulating capacity: (250ml --- 5000ML)

3、 Operating instructions

1. Set temperature: press the set key to set the temperature. Press the set key to set the temperature. Press the set key to set the temperature of the instrument. Press the Δ key to increase the setting value, press the ▽ key to decrease the setting value. Press the increase or decrease key continuously to set the temperature rapidly. Once again, the instrument returns to the normal working state and the temperature is set.

2. Sensor error correction: when reconfirming that the value displayed by the instrument is not the correct measurement value, the displayed value can be corrected. Press set key for 3 seconds, and the instrument will enter the inner menu. After the parameter SC is selected, this parameter can be modified by using the Δ or ▽ keys. The correction range of sensor error is from + 50 ℃ to - 50 ℃. After correction, press set key for 3 seconds to exit. The correction value of the instrument is 0 when it is delivered from the factory. It is necessary to prevent the instrument with correct display from being corrected to incorrect.

4、 Precautions

As the surface of glass fiber is coated with a layer of grease, it is necessary to slowly raise the temperature for the first time, turn off the power supply after generating white smoke, and then pass through again and again after the smoke is dispersed. It can be used formally after being electrified and smokeless

The product must be grounded, and it should be dry when stored, and should not be affected by moisture. If it is wet, pay attention to the induction electricity when using, do not touch it by hand, and slowly raise the temperature, so that the good insulation performance can be recovered after drying
