HJ-4A digital display constant temperature multi head magnetic stirrer can control temperature independently

1、 Product introduction:
  HJ-4A digital display constant temperature multi head magnetic stirrer (also known as multi head digital display constant temperature magnetic stirrer, multi head constant temperature magnetic stirrer, quadruple constant temperature magnetic stirrer and four working digit display constant temperature magnetic stirrer) is improved on the basis of our company's research and production of magnetic heating agitator. It has the functions of single point and multi-point simultaneous stirring and constant temperature heating, which is easy to operate, stable in operation, and free from pollution Stage speed regulation, digital display temperature control. The agitator made of PTFE and high-quality magnetic steel has the advantages of high temperature resistance, wear resistance, chemical corrosion resistance and strong magnetism. It can accurately and stably stir the liquid solution at a wide speed range. It is especially suitable for constant temperature stirring and comparative test of small volume samples. HJ-4A digital display constant temperature multi head magnetic stirrer is a necessary tool for petroleum, chemical, medical and health, environmental protection, biochemical analysis, education and scientific research laboratory, which is ideal and convenient to use.

How to use HJ-4A digital display constant temperature multi head magnetic stirrer:
  When using, please first check whether the accessories are complete, and then install the fixture in order, put the beaker to be stirred in the center of the chromium plating plate, add the solution, put the stirrer in the beaker solution, and then plug in the power plug of the instrument, then turn on the power switch, and the indicator light will be on. The speed regulation is gradually adjusted from low speed to high speed, and high speed is not allowed The speed gear can be started directly, so as to prevent the agitator from being out of sync and causing jumping. Set the required heating temperature. Cut off the power supply when not working. In order to ensure safety, please connect the ground wire when using. Keep it clean and dry. Do not allow the solution to enter the machine, so as to avoid damage to the parts and severe vibration

Precautions for using HJ-4A digital display constant temperature multi head magnetic stirrer:
1. When the stirrer jumps or does not stir, please cut off the power supply to check whether the bottom of the beaker is flat and the position is correct. At the same time, please check whether the current voltage is between 220 V + 10 V, otherwise the above situation will occur.

2. The heating time should not be too long, and the service life of the gap can be prolonged.

3. It can work continuously at medium speed.
