Melting point NU-138E

The instrument basically consists of a miniature furnace with Auto controlled heating rate arrangement, an air circulating arrangement and Digital temp. Indication with necessary controls. When the Start key is pressed, heating starts. There is Auto detection of Opto-coupled light transmission system , Whensample melts , photodiode detects the signal and Melting Temperature put on hold / latched on display automatically. The furnace becomes off and the cooling fan ON simultaneously. The instrument gives audio visual indications. The Melting Temp. of the sample remain displayed on the panel till the RESET switch is operated.

Not Suitable for Dark Colored Samples. Opto-coupled light transmission based, Sample required to be transparent at the time of melting.

OPERATION : Fully Automatic Sample Fill and Forget : All the selection of programming is fully protected from power failure including HOLD action of melting temperature. Once the start action is initiated, it will reach to find out the melting point of sample, even multiple time power failure.
