ACCESSORIES

The following accessories may be used with the PU9700 Series instruments:

Purge Kit

This kit provides sealing of the covers, cell compartment lid and a heat sink for the heat from the source thus allowing dry air purging of the instruments. lt should be factory fitted as a optional extra to the PU9706, PU9716, PU9714 and PU9712 instruments.

SP3-060 Air Dryer

This unit supplies 40 litres/minute (1. 55 cu.ft/minute) of dry air at below —70°C dewpoint. The services required are:

(a)    Mains electrical supply of 115V or 230V (50 or 60Hz), 75VA.

(b)    Supply of compressed air at pressures between 4.2 and 8.4 kg/cm ² (60 and 120 lb/in ² ).

The Air Dryer is supplied complete with filters, gauges and controllers. Full details are given in the Instruction Booklet which accompanies the accessory.

lnfra-red Data Station

The PU9700 can be driven by the IR Data Station via the ACCESSORY port on the accessory interface panel at the rear right-hand side of the main instrument (Fig 1 .2). Full details are given in the manual which accompanies the accessory.

PU9702 Absorbance Accessory

The PU9702 Absorbance Accessory is used with the PU9700 Series of IR spectrophotometers to convert the recorder signal from transmission to absorbance in the range OA to 2A. lt is connected to the ACCESSORY socket on the Accessory Interface Panel. Full information is contained in the PU9702 Users Manual 9499 230 10711 that accompanies the accessory.
