General description
2. General description
DAIRYSCAN JET 1 is designed for percentage analysis of Fat, Solids-
Non-Fat (SNF), Density, Protein, Lactose, Salts, Water content,
Freezing point, Temperature (°C) and Conductivity (option). Тhose
components can all be measured at the same time.
The device can measure three types of milk. Factory preset is for cow
milk. Upon user’s request the device can be calibrated for other types
of milk.
The device has a compact design with a robust structure and a user-
friendly interface. Most importantly, the one-button operation is
extremely simple –you press only once to start measuring, you press
only once for cleaning. DAIRYSCAN JET 1 can analyse three types of
milk defined by user. The measuring cycle is 60/90 samples per hour.
The samples are precisely dosed and small quantities are required –
the sample volume is 15cm³. No thermal or mechanical treatment of
the samples before analysis is necessary. No use of chemical
reagents is required. The working conditions are as follows –
temperatures from 10° to 40°C (option 43°C), Relative Humidity from
30% to 80%.
With regard to the “moisture problem” which remains of much
significance the front panel of the device is designed to operate when
with wet hands. In addition to this DAIRYSCAN provides a one-year
full warranty.

Samples preparation
4. Samples preparation
In order that most accurate results are obtained it is important that the
milk be kept for 2 hours after milking and stirred well before being used
for sample material. A good way to stir up the milk is to pour it several
times out of one vessel into another and back. Before analysis the
samples have to be filtered in order to be free from foreign fragments.
Milk samples should be 1-40°C (option 43°C). Full cream samples
containing fat over 10% should be heated up to 42-43°C and then
cooled to 25-30°C. If the sample temperature is over 40°C the
message “Sample overheated” will appear on the display. Use milk
samples only once and do not return it to the vessel. Samples can be
kept for a maximum of 2 days if they are stored at a temperature not
exceeding 5°С.

Working description
Preparing the device
1. Place the device on a horizontal and stable surface.
Caution: Any sources of hot or cold air can influence the
accuracy of the measurements.
2. Connect the power cord 220V AC to the power socket on the
rear panel of the unit and plug it into the electrical outlet (the
outlet has to be grounded, see “Important Safety
Instructions”.
3. Turn on the POWER switch and DAIRYSCAN JET 1 will be
ready for use. Before proceeding, please read and follow the
rest of the instructions in this chapter!
Powering by an external 12V DC power source
DAIRYSCAN JET 1 can be used in places where no regular electrical
supply is available, DAIRYSCAN JET 1 can be powered by your car
battery or other 12V DC external power sources. DAIRYSCAN JET 1
has provided a cable suitable for this purpose. To use this option,
follow the procedure described below:
1. Unplug the 220V AC power cable from the socket on the rear
panel of the unit and then from the electrical outlet.
2. Connect the supplied power cord 12V DC to the Power-in
socket 12V DC socket on the rear panel of the unit and plug
the other end of the cable into the electrical lighter socket
inside your vehicle.
3. The device will be turned on immediately. After starting the
unit goes into system check mode and will be ready for
analyses in about 1 minute.
