The Electroson 900 – 1 & 3 MHz Ultrasonic Therapy Machine is a professional therapeutic device designed to deliver controlled ultrasonic energy at 1 MHz and 3 MHz frequencies. The dual-frequency configuration provides physiotherapists with flexibility to select the appropriate frequency according to the treatment area and clinical requirement.
It is designed for use in physiotherapy clinics, rehabilitation centers, hospitals, sports therapy facilities, and other professional treatment environments.

What Is Electroson 900?
The Electroson 900 is a dual-frequency ultrasonic therapy machine that operates at 1 MHz and 3 MHz.
Ultrasonic therapy uses high-frequency acoustic energy delivered through a treatment applicator. The therapist selects the appropriate frequency and treatment parameters based on the patient’s condition, treatment objective, and professional protocol.
1 MHz Frequency
The 1 MHz setting is generally selected when treatment is intended for relatively deeper tissues.
3 MHz Frequency
The 3 MHz setting is generally used when a more superficial treatment depth is desired.
The appropriate frequency should always be selected by a qualified physiotherapist.

How to Use Electroson 900
The machine should be operated by a trained physiotherapist or qualified healthcare professional.
Step 1: Assess the Patient
Assess the patient’s condition and determine whether ultrasonic therapy is appropriate.
Step 2: Check the Machine
Inspect:
- Power cable
- Applicator
- Applicator cable
- Display
- Controls
- Machine housing
Do not use the equipment if any component is damaged.
Step 3: Prepare the Treatment Area
Clean and prepare the selected treatment area according to professional practice.
Step 4: Apply Coupling Medium
Apply a suitable ultrasonic coupling gel to the treatment area to maintain proper contact between the applicator and skin.
Step 5: Select the Frequency
Select 1 MHz or 3 MHz according to the treatment plan and clinical requirement.
Step 6: Set Treatment Parameters
Select the appropriate treatment settings according to the patient’s condition and manufacturer’s instructions.

Step 7: Set the Timer
Set the required treatment duration using the available timer.
Step 8: Position the Applicator
Place the applicator gently against the treatment area with adequate coupling medium.
Step 9: Move the Applicator
Move the applicator continuously using the technique recommended by the manufacturer and qualified professional.
Avoid leaving an active applicator stationary unless specifically permitted by the manufacturer’s instructions.
Step 10: Monitor the Patient
Monitor the patient’s comfort throughout treatment.
Stop the treatment if significant pain, excessive warmth, or unusual discomfort occurs.
Step 11: Complete the Treatment
Stop the ultrasonic output before removing the applicator from the treatment area.
Step 12: Clean the Applicator
Remove the coupling gel and clean the applicator according to the manufacturer’s instructions before storage.
Safety Precautions
- Operate the machine under qualified professional supervision.
- Follow the manufacturer’s instructions.
- Inspect the applicator and cables before every treatment.
- Use an appropriate coupling medium.
- Maintain proper applicator contact.
- Keep the applicator moving as recommended.
- Do not unnecessarily increase intensity or treatment duration.
- Monitor the patient’s response throughout treatment.
- Stop treatment if significant discomfort occurs.
- Do not use damaged accessories.
- Follow professional contraindication guidelines.
- Clean and store the applicator properly after treatment.
