Pentode Characteristics with power supply and 2 meters (C.R.) (V.V.) Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12163
Indian Lab Suppliers supplies the Pentode Characteristics with power supply and 2 meters (C.R.) (V.V.) (Product ID: 12163) as part of its electronics engineering lab equipment range. It is a self-contained set-up for plotting the plate and mutual characteristics of a vacuum pentode.
Quick Answer
Built-in supplies are a continuously variable 0–300 V DC, 100 mA regulated plate supply, a 40–300 V DC, 30 mA regulated supply for the screen grid, a 0 to ±10 V DC, 10 mA bias supply and 6.3 V AC, 600 mA for the filament. Meters read 0–300 V, 0–±10 V and plate current on 30 mA and 100 mA ranges. Students plot the curves and calculate the tube constants; the flat plate curves show the high plate resistance that the suppressor grid gives a pentode. The name mentions 2 meters while three are listed, and the weight and size are not stated; please confirm at quotation.

Where This Is Used
Completes the valve set with the Triode Characteristics with power supply and 2 meters (C.R.) (V.V.) (Product ID: 12162) and Tetrode Characteristics with power supply and 4 meters (C.R.) (V.V.) (Product ID: 12174). The plate supply reaches 300 V DC, which can give a dangerous shock, and the valve gets hot: use it under supervision and switch off before changing any lead.
