3 Product-specific information
• Not suitable for children under 14 years
• Do not carry out measurements on live components.
• Do not expose handles and feed lines to temperatures in excess of 60°C
unless they are expressly approved for higher temperatures. Temperature
specifications on probes/sensors refer only to the measuring range of the
sensor system.
• Only open the measuring instrument if this is expressly described in the
documentation for the purposes of maintenance or servicing.
4 Intended use
The testo 270 BT is a handy measuring instrument for fast testing of cooking
oils.
The TPM value (total polar materials) enables a statement on the ageing of
cooking oils due to the effects of heat.
The following measuring tasks can be performed with the testo 270 BT:
• Displaying the temperature of the cooking oil:
Indicator for correct setting of the deep fat fryer, checking of integrated
temperature displays.
• Displaying the TPM value:
Indicator for the ageing of the cooking oil.
The sensor works on a capacitive basis and determines as the reading the total
polar materials as a %.
The free fatty acids, which are determined above all for the evaluation of
unloaded oils (rancidity), cannot be detected with the testo 270 BT.
The temperature of the cooking oil to be measured must be at least
40 °C. The maximum operating temperature is 200 °C.
The testo 270 BT must be held in the hand for the duration of the
measurement.
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)1935/2004.
