Product Description
The large clearly-readable display enable a smooth reading of the measured value, which can be displayed in °C or °F. With the HOLD-function the measured value can be "frozen" and inscribed in a diagram. An automatic switch-off prevents for unnecessary battery discharge.
There are 4 different standard probes available. For customized solutions all standard probes can be also offered as special probes (different length and diameter).
