CRUCIBLE, MUFFLE, TUBE, ELECTRIC FURNACES, PYROMETERS for LABORATORY WORK. We shall be pleased to quote for Electric Furnaces to any special design. Dear Sirs, We have from time to time drawn your special attention to the Small Portable Moving Coil, Multi-Range Instrument called the "Alltest." Very large numbers of these have been sold and the only criticism to which it has been subjected is that an instrument having a scale length of 2 5/8" does not meet all the requirements for convenient use in a Physical Laboratory. We have, therefore, produced a similar movement giving full scale deflection with the standard ranges of 75 m/v and 15 m/a, mounted into a switchboard pattern case, suitable for mounting on an inverted "T" batten. The front of the instrument is entirely glazed | ||
