Ultrasonic Activity eter
Ultrawave’s hygea
®
Ultrasonic ctivity Meter provides a fast, effective and
simple method of measuring the ultrasonic activity generated in Ultrawave’s
ultrasonic baths.
By measuring the frequency and power level generated within the cleaning fluid,
the hygea
®
Ultrasonic ctivity Meter provides assurances that the bath is
performing at the optimum level.
Ultrawave’s hygea
®
Ultrasonic ctivity Meter is an easy-to-use alternative to the
traditional foil ablation test.
Why measure?
The need to confirm the performance of all processing equipment in healthcare
and industrial manufacturing environments is all important.
HTM01-05 recommends that a measurement of ultrasonic activity in dental
ultrasonic baths is taken on a regular basis. Some health trusts and organizations
now recognize the hygea
®
Ultrasonic ctivity Meter as an alternative to the foil
ablation test and have approved its use for measuring the bath’s performance.
The hygea
®
Ultrasonic ctivity Meter is also used in many manufacturing and
processing industries where Ultrawave ultrasonic systems are a key part of the
manufacturing process.
How it works
The hygea
®
Ultrasonic ctivity Meter is constructed from a stainless-steel probe,
fitted with a specially designed ultrasonic receiver. The probe is connected to a
hand-held meter with two LED bar graphs.
When the probe is inserted into the cleaning fluid and the button on the meter
is pressed, the LED bar graph displays a measurement for the frequency and
power generated within the cleaning fluid.
This indicates and measures the level of ultrasonic activity and ensures that the
ultrasonic cleaner is working at optimum efficiency.

Operating Instructions
1. The hygea
®
Ultrasonic ctivity Meter should be used to measure the level
of ultrasonic activity throughout the tank.
Due to possible variations in the level of energy at different points
throughout an ultrasonic bath, it is necessary to measure at different points
on the X, Y and Z axis.
It is recommended that the tank be divided into 9 sections and
measurements taken 30mm below the surface and 30mm above the base
of the bath.

For tanks <150mm deep, it is sufficient to take measurements at one level
only, ½ way down the water column.
2. Fill the ultrasonic tank with water to the required level and add detergent at
the normal dose. Note: the same dose should be used each time
measurements are taken.
3. Run the ultrasonics to ensure the fluid is degassed. (See page 6 for the
importance of degassing.)

C6023503-01 November 2020 Page 4
4. If the unit has a heating function, set the temperature to the required
level. Note: the same temperature should be used each time
measurements are taken. (See page 6 for information on the effect of
temperature.)
5. Once the fluid is degassed and the
required temperature is achieved,
start an ultrasonic cycle. Insert the
probe into the cleaning fluid while the
ultrasonics is running.
6. To take a reading, press and hold the
button on the meter. Record the
results displayed on both the
Frequency and Power displays.
Note: it is important that only the
stainless-steel probe wand comes into contact with the cleaning fluid. If
the handle, connector or display unit gets wet, it may damage the Meter.
7. The probe should be placed in the 18 measurement positions and the
results recorded. For consistent measurement, the Probe should be
placed in the same 18 locations each time measurements are taken.
8. Record the results so that future tests can be compared. log book is
available from Ultrawave for recording the results. If there is a reduction
in the readings over time, your ultrasonic cleaning system may not be
working at full efficiency and may need validation and servicing.
Note: It should not be expected that the Meter will give readings of 100% every
time. The hygea
®
Ultrasonic ctivity Meter is designed to be used as a
comparative measurement device over a period of time.
The hygea
®
Ultrasonic ctivity Meter has been optimized for use in Ultrawave
units. The Meter should not be used to compare the performance of different
baths but should be used as a comparative measurement of the performance of
one individual bath over time.

C6023502-03 November 2020 Page 5
Performance
Each ultrasonic bath may not run at the exact same frequency; therefore, the
Hygea Ultrasonic ctivity Meter will not necessarily give the same readings in
two baths that are performing equally well.
The ctivity Meter should be used to compare a bath over a period of time rather
than to compare two different baths alongside each other. Should the
measurements recorded in an individual bath change significantly over a period
of time, it is recommended that you contact Ultrawave for information and advice.

ultrasonic cleaning systems.
easuring ultrasonic baths with Frequency Leap
Technology.
Some Ultrawave ultrasonic baths have Frequency Leap technology.
Due to the nature of the pseudo random frequency change while in Leap mode,
the probe readings may vary second to second. To perform a more defined
measurement with these units, please switch to single frequency mode before
measuring ultrasonic activity with the Hygea ctivity Meter.
Calibration
The Hygea Ultrasonic ctivity Meter requires annual calibration to ensure that it
is still providing accurate measurements.
Calibration of the Hygea Ultrasonic ctivity Meter needs to occur at Ultrawave
under strict calibration conditions. When your Meter is ready for calibration (12
months after date of sale) contact Ultrawave to arrange this chargeable service:

Please note that there is no recognized international standard unit (SI unit) of
ultrasonic activity, therefore your hygea

Ultrasonic ctivity Meter calibration
is not traceable to national standards.

Ultrasonic Activity eter good practice
The need to degas: In order to allow optimum ultrasonic activity, the gases
present in ordinary tap water need to be driven out of the cleaning solution.
The time needed to degas the liquid varies depending on the amount of gas
present in the liquid and the quantity of water in the tank. Ultrawave
recommends a degas period of at least 10 minutes.
During the degas cycle, you will see bubbles of gas forming on the inside of the
bath, and slowly rising to the surface. Degassing is complete when you can no
longer see these bubbles.
nother indication of increased “cold-boiling” at the liquid surface indicates that
the liquid is degassed.
Once the liquid is degassed, the bath is immediately useable and will run the
cleaning cycle.
The effect of heat: Heating the liquid in the bath will aid the cleaning process.
Normally a temperature of
between 37 to 65°C is sufficient
to accelerate the process.
However, when cleaning medical
instruments, the maximum
temperature should be set to
45°C. Cleaning at above 45°C
may cause proteins to coagulate
and “bake on” to the instruments.
Ultrasonic activity itself will heat up the liquid at a rate of approximately
10-15°C per hour if in continuous use.
Detergents: Ultrasonic baths require the presence of a cleaning detergent to
work most effectively. When using the Hygea Ultrasonic ctivity Meter ensure
that detergent is added to the water in the bath.
