LOG LINEAR ADAPTER This adapter converts the output signal from amino acid analyzers, automatic colorimetric analyzers and spectrometers to a concentrationlinear signal which is then automatically integrated.
The best digital integrator now interfaces ATOMIC ABSORPTION ADAPTER with any The output from either manual or automatic analytical lab sampling atomic absorption spectrometers are converted by this adapter to a numerical value instrument. which is a function of concentration.
DIGITAL RECORDING ADAPTER DTA ADAPTER
This adapter converts the 1504 integrator to a printing analog to digital converter. The combination automatically samples any electrical signal on a pre-selected time base and prints out integrated values which represent data points as a function of time.
Exothermic and endothermic transitions that produce positive and negative going signals are converted by this Differential Thermal Analysis Adapter to all positive going signals for quantitation and printout.
TAPE PUNCH ADAPTER The adapter codes each integral and retention time generated by the 1504 and punches this coded number onto paper tape suitable for computer entry. An optional alpha-numeric keyboard permits sample identification and instructions to be entered on the tape. Model 1504 Digital Integrator is a third generation instrument that interfaces with all lab voltage analogs., and provides not only digital equivalents of peak areas from both linear and non-linear outputs, but also data points on the curve or time dependent integrals. Plug-in adapters allow precise integration of colorimeter signals, computer logic, metal ion concentration or quantitation of both endothermic and exothermic thermal transitions. When you add a baseline compensator and time printout device, it's easy to understand why Nester/Faust's 1504 solves almost every analytical situation. Nester/Faust Mfg.
