New Product Testo 175-T2 2-Ch. Temperature Data Logger, Internal (NTC) and Ext Sensor (NTC) 0572 1752    Product Description  The testo 175 T2 temperature data logger has an internal sensor and a connection for an external temperature probe. This means it is ideally suited for use when you do not just want to record the indoor air temperature, but also want to carry out another temperature check (e.g. a core temperature spot check).  This is practical when storing and processing food, amongst other things: measure the ambient conditions of your goods in storage areas and cold stores and at the same time check the temperature level of the goods themselves – for example with a penetration probe (optional). Temperature control in the gaps in the packages is also possible. The measurement results from both channels are securely stored in your temperature data logger.       Temperature - NTC          Measuring range    -35 to +55 °C internal -40 to +120 °C external        Accuracy    internal: ±0.5 °C (-35 to +55 °C) ±1 Digit external: ±0.3 °C (-40 to +120 °C) ±1 Digit        Resolution    0.1 °C                 General technical data          Weight    160 g        Dimensions    89 x 53 x 27 mm        Operating temperature    -35 to +55 °C        Product-/housing material    Plastic        Protection class    IP65        Channels    1 internal; 1 external        Product colour    white        Standards    EU-guideline 2014/30/EU; 2011/65/EU; DIN EN 12830        Measuring rate    10 s - 24 h        Battery type    3 x AIMn type AAA or Energizer (not included package)        Battery life    3 years (15 min. meas. rate, +25 °C)        Interface    mini usb, SD card slot        Memory    1,000,000 measuring values        Storage temperature    -35 to +55 °C
