Graphic Y/t Range
Simple
Plug in and go real time recording. Change applications in minutes. No programming or messing around.
Versatile
One or two pens. Record any analogue output against time. Applications across most industries and scientific disciplines.
Direct Inputs
Voltage outputs. Switchable 50/60Hz filter pH electrodes. Thermocouples.
Portable
Order complete with waterproof carrying case and rechargeable battery packs.
Robust
Proven in the field. Used in cement works. Goes where PCs do not dare.
The isolated low voltage supply safeguards both the operator and peripheral equipment used with the recorder. Those requiring only one pen may choose between the Graphic 450X with mechanical pen lift and permanently fitted standard pre-amplifier, or the more versatile Graphic 1000 with electronic pen lift, remote control options and range of optional pre-amplifiers.
Contact closure or TTL will activate the pen lift, event markers and chart drive. The chart speeds are controlled by pulse frequencies. The voltage zero and full scale deflection (fsd) calibration facilities allow an infinite array of calibrated ranges. Back-off is extended from 100% with the standard pre-amplifier to 1000%, in 10 steps of 100%, with the high performance pre-amplifier. Both dc voltage amplifiers have a switchable 50/60Hz filter, making them highly resilient to changes in the supply voltage.
The Graphic 1002 provides two isolated channels with fully adjustable writing areas.
Graphic Y/T Pre-Amplifiers
Standard DC Voltage Pre-amplifier (01/1331)
5 pre-calibrated ranges 1mV to 10V, plus an infinite number of intermediate sensitivities with a maximum input of 150V. Adjustable true zero, full scale deflection and pen position on chart. Selectable (50/60Hz) filter.
Switchable left or right hand zero. Event marker.
High Performance DC Voltage Pre-amplifier (01/1332)
As for the standard pre-amplifier plus: 15 pre-calibrated ranges 1mV to 100V; 1000% back of in 10 steps of 100%. Back off, or zero suppression, enhances the readability of small changes in large signals. Up to 10 times the nominal range of the signal can be subtracted allowing a higher sensitivity to be used.
Thermocouple (01/1597)
J, K or T type thermocouple input via standard miniature input socket. Lineraised for temperatures from 0°C to 100°C, 200°C or 500°C full scale calibration. Adjustable zero position of pen on chart.
Platimun Resistance (01/1699)
100 Ohm standard platinum resistance thermometer input via 5 way plug. Full scale pre-calibrated ranges 0°C to 50°C, 100°C, 200°C, 500°C and 1000°C. Back off in 10 steps of 50°C. Zero position of pen on chart adjustable. Event marker.
