1041, Time Electronic

Time Electronics Model 1041 Low Ohm Decade Resistance Box Time Electronics 1041 is a precision low ohm resistance box designed for general laboratory work, including platinum resistance thermometry. The 1041 is compact and durable. It is housed in a robust metal case with removable protective rubber cover which facilitates use not only in the laboratory but also in the field. Excellent accuracy is achieved through using high stability metal film resistors. The 5-digit thumbwheel switch enables simple and precise setting with a clear indication of the resistance value. Range/resolution 0 - 1kΩ / 0.01 Ω steps High accuracy Clear visual indication, using colour-coded digits High stability Low temperature coefficient 50 ppm/°C Safety terminals (compatible with 4mm shrouded plugs, standard plugs, bare wires, spade terminals) Residual resistance Power Rating 1W per resistor Voltage Rating: Maximum 100 V DC/AC RMS Suitable for PRT/RTD Removable protective cover Dimensions 215(W) x 100(H) x 120(D) mm Weight 1kg
