recorder For dual-detection gas chromatography and simi lar applications where two related phenomena must be compared to the same time base, there is nothing to equal the convenience of a dual-channel servo/riter recorder. One chart drive, one piece of paper assure an absolute time relationship. Adjust able zero p o s i t i o n i n g — s t a n d a r d on every servo/riter—permits left, right or center base lines. When desired, overlapping pens can utilize the full 9%-inch chart grid for maximum resolution.
Only servo I riter recorders offer so many extra features at no extra cost. At least 40,000 ohms off-balance input impedance, Vi -second pen speed, interference rejection as high as 3,000,000 to 1 . . . plus the widest selection of ranges and input forms. Choose the space-saving flush-mounting model to replace two standard single-channel re corders or choose the laboratory-styled portable for bench-top convenience with writing-desk chart carriage and up-front controls and terminals. *A trademark of Texas Instruments
