scalers: review advice
Visit provided by Mr. Chairman, G.
Balfry\'s letter about pacemakers and ultrasound cattle (2005; : 625)
I recently saw two patients with a pacemaker inserted.
Both cards have the manufacturer\'s details and the type of pacemaker inserted.
Google search results show the manufacturer\'s web address.
I sent an email to the company saying I would like to use the ultrasonic scaler (type specified)
For patients, the premise is that it does not interfere with the function of the pacemaker.
From the email response received, ultrasound scaling can be used for these patients.
Email communication is also part of patient records.
Before the list of pacemakers is available, it is recommended to email the pacemakers based on the patient\'s specific circumstances and follow their advice on using an ultrasonic scaler.
I think the long-standing recommendation that patients with pacemakers do not use an ultrasonic cleanser is no longer valid and should be reviewed according to the patient\'s specific circumstances.
Hydraulic universal testing machines have very high accuracy requirements.
The hydraulic system is the power drive mechanism of the tensile testing machine.
The specific application of the electronic universal testing machine in the automobile manufacturing process: The electronic universal testing machine needs to be used for automobile parts.
Wave soldering refers to the molten solder (lead-tin alloy), sprayed by electric pump or electromagnetic pump into the solder wave required by the design, can also be formed by injecting nitrogen into the solder pool, so that it is pre-loaded The printed board of the component realizes the soft soldering of the mechanical and electrical connection between the solder end or the pin of the component and the pad of the printed board through the solder wave.
The frequency converter is a power control equipment that uses frequency conversion technology and microelectronics technology to control AC motors by changing the frequency of the motor's working power supply.
Electronic universal testing machine is a necessary equipment to control the quality of products.
The calibration operation of the electronic universal testing machine is still relatively unfamiliar to friends who use it for the first time.
Selective wave soldering defects and their prevention.
Testing machine, broadly speaking, is an instrument that verifies the quality or performance of a product or material according to the design requirements before it is put into use.
The tensile force is not an accurate value after being measured by the testing machine, and subsequent calculations are required to get the desired value.
