1. INTRODUCTION
A high precision portable thermometer for metrology and other exacting laboratory applications, the DP97 is a proven instrument used world wide as a laboratory and site standard in pharmaceuticals, medical, food, environmental testing, R & D, and general industrial applications. It is particularly suitable as the reference standard for temperature calibration baths.
The DP97 Digital Thermometer utilises highly advanced microprocessor circuit design to achieve exceptional measuring accuracy, linearisation conformity and stability in a versatile but easy to use configuration.
Based on a high resolution 20 Bit Analogue to Digital Converter, all measurement computations are performed digitally without drift. The 5 digit LED display provides a readout to 0.01°C over the entire
Single or dual Pt100 3 or 4 wire sensors are accepted; the DP97 will automatically recognise and select 3 or 4 wire mode. Display of input A, B OR
An RS232 interface (remote control and measure) is fitted as standard and isolation is incorporated. An analogue (retransmission) output is also fitted as standard; the 1V dc output is programmable between lower and upper set limits.
Calibrated sensors can have their calibration points programmed into the DP97 via a personal computer using Labfacility software. The instrument then digitally self calibrates to the probe(s) providing corrected temperature readout to give optimum system accuracy.
The
Primary power is provided by an internal,
A range of precision stainless steel sheath Pt100 probes is available for the DP97.
