Thermometer

The KM330 and KM340 hand held industrial thermometers are
easy to use, with proven type K thermocouple technology and a
wide range of optional probes and sensors.

KM330 is a single input thermometer with a wide range of
applications. Users can select readings in °C of °F and high or
standard resolution to suit their requirements. Hold and Max
functions are provided, to freeze the last reading on the display
and to record the maximum value. Hold will also freeze the last
maximum value.

KM340 is a twin input differential thermometer for many
applications, such as heating and ventilation, scientifi c
research and industrial processes. Three display modes can be
selected to show values from either input, or the
difference between them, in °C or °F scales. Hold and Max
functions are fi tted and apply to all values.
