DescriptionThe DP9602 provides precise platinum resistance thermometer temperature measurement and logging for exacting applications in both laboratory and site locations. It is an exceptionally accurate and stabledigital thermometer particularly suitable for use with thermal calibration baths as a reference standard. The DP9602 is fully characterised for Pt100 sensors and all major thermocouples J, K, N, T, E, R, S and B. Exceptionally stable automatic cold junction compensation with a rejection of 100:1 is incorporated for thermocouple ranges. Alternatively, external or manual referencing can be selected as required. Applications include medical, pharmaceutical, food, environmental testing, R&D and educational establishments. Displayed values and user information are indicated on a bright clear LED screen with diffused backlighting. Data can be displayed in °C, °F, Kelvin, ohms or mV as required; nine front panel push keys, the only user controls, are used in conjunction with the display screen. It is this arrangement which makes for very simple and “friendly” operation. There are four input ports, two for thermocouples and two for 3- or 4-wire Pt100 sensors; the instrument automatically recognizes 3- or 4-wire configurations. The DP9602 can accept two Pt100 sensors and/or two thermocouples of similar or different types. The measured temperature can be displayed directly from one of the inputs or differentially between similar or different inputs. Differential temperature and the two individual channel temperatures are displayed simultaneously. All four inputs can be scanned and values logged according to parameters set up by the user in the PC software; the instrument incorporates a real-time clock and on-board memory. A flash drive USB port is provided to allow data to be stored and/or exported. PC software running in Windows® is provided as standard; it allows programming of custom calibration, remote control and measure and logging functions.
