Practical tips before commissioning your new testo 270
Dear customer,
Congratulations on your purchase of the new testo 270 deep-frying oil tester.
All of our measuring instruments are checked by us in the factory before the
delivery and adjusted to their specific accuracy. To ensure that the accuracy
remains at the same high level, we recommend checking the instruments
regularly.
With the testo 270 deep-frying oil tester, you have the following options:
1testo factory calibration according to ISO (accuracy +/- 2 % TPM):
With the order number 0520 0028 you can order an ISO calibration from
Testo's calibration subsidiary, Testo Industrial Services in Kirchzarten. In the
process, your testo 270 is calibrated at two points (at approx. 3 % and at
approx. 24 % TPM) under precise laboratory conditions.
Furthermore, you have the following options for checking your testo 270 yourself
at any time:
2with testo reference oil (accuracy +/- 2.5 % TPM):
With the included testo reference oil, you can check the measuring
instrument precisely and readjust it, if necessary (please observe the
description in the instruction manual for this).
You can reorder the testo reference oil at any time individually (0554 2650)
or in a three-pack (0554 2651).
3with the simple function test in deep-frying oil (accuracy +/- 3 % TPM):
For a simple function test without adjustment, we recommend a
measurement during the commissioning of your new instrument in unused
deep-frying oil at 150 to 180 °C.
You should ideally perform this measurement repeatedly in succession and
note the respective readings. The average of these readings is your specific
reference value for subsequent instrument testing. To use the determined
reference value as a comparative reading for a check, always perform the
measurement for instrument testing in unused deep-frying oil at 150 to
180 °C.
Please note that when changing the type of oil or the oil supplier, the
reference value must be determined anew.
Your specific reference value:

The testo 270 is a handy measuring instrument for the fast
inspection of deep-frying oils and is designed in equal measure for
left and right handers.
The TPM value (total polar materials) enables a statement on the
ageing of deep-frying oils due to the effects of heat.
The following measuring tasks can be performed with the testo
270:
• Display temperature of the deep-frying oil:
Indicator for correct setting of the deep-fryer, inspection of
integrated temperature displays.
• Display TPM value:
Indicator for the ageing of the deep-frying oil.
The sensor works on a capacitive basis and determines the total
amount of polar materials in % as the reading.
The free fatty acids that are determined above all for the evaluation
of unloaded oils (rancidity) cannot be detected with the testo 270.
The temperature of the deep-frying oil to be measured must
be at least 40 °C. The maximum operating temperature is
190 °C, for brief periods 200 °C.
The following components of the product are designed
according to Regulation (EC) 1935/2004 for long-term
contact with foodstuffs:
The sensor and the probe tube are designed to come into
contact with oil used in deep fat fryers for the typical
duration of a spot check measurement. The materials used
in these components meet the relevant requirements in the
Regulation (EC)1975/2004.
