The DP9602 provides platinum resistance thermometer and thermocouple temperature measurement and logging for precision applications in both laboratory and site locations. It is an exceptionally accurate and stable digital 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 back-lighting. 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.
Specifications
Inputs/Ranges/Sensors
Types:
Overall Accuracy:
Note: Type B not characterized below 200°C (392°F).
Linearisation Conformity:
Note: Performance of ADC (0.5µV resolution ) is superior to published thermocouple table best resolution of 1µV.
Stability (vs Ambient Temperature):
Warm-Up: Negligible under normal ambient conditions; allow 5 to 10 minutes for full stability unless stored at low temperature, then 30 minutes minimum
Cold Junction Compensation: Automatic on all thermocouple ranges; better than ±1°C max shift for ±10°C ambient variation (100:1) or external via Pt100 on channel A or B or manual input of CJ temperature value
Pt100 Sensor Current: 0.5 mA
Resolution of Data Display: Pt100 0.01/0.001 user select for °’C, K and O
Variable Filter: Sampling rate selectable between 4 and 64 (measurements averaged per reading)
Thermocouples: 0.1°C all ranges
Measurement Units: °C, °F, K, O or mV as applicable to sensor
Measurement Modes: A, B or A-B; any combination of sensor types
Custom Calibration: Up to 10 calibration values can be allocated to Pt100 input A & B and to thermocouples input A & B; values are retained in non-volatile memory until replaced by user; alternatively, for Pt100 inputs ITS 90 or IPTS 68 coefficients can be used for custom calibration
Smart Sensor Connection: Pt100 inputs only; correction values stored in connector
Null Function: Corrects differential temperature readout between two sensors to zero
Sensor Lead:
Logging: 8000 readings
Supply: Internal lithium Ion rechargeable batteries; mains 90 to 260V 50/60 Hz universal adaptor included; battery charge life up to 12 hours with full charge
Series Mode Rejection: 60 dB @ 50 Hz (50 mV RMS applied)
Common Mode Rejection: 30V RMS applied between input and earth produces no measurable effect
Display: 128 x 64 pixel OLED with diffused backlighting; wide viewing angle, high contrast (adjustable)
Front Panel Controls: 9 membrane push-keys to control all instrument functions
Mechanical/Case: Metal bench top case/adjustable tilt
Dimensions Overall: 190 W x 70 H x 250 mm D
Weight: 3 kg approx
Input Connections: 2 x Pt100 via D type connectors 2 x thermocouple via standard sockets
USB Serial Communications: Isolated, 38400 Baud, 8 data, no parity, 1 stop bit; remote control and measure
PC Software (Standard): Supplied as standard on CD ROM; remote control and measure; log readings to file/download to PC/programming corrections
Analogue Output (Standard): User programmable, 0 to 1 Vdc
Precision Pt100 Probes: 304 stainless steel probes, 6 mm Dia. with 2 m screened PTFE lead and Pt100 probes and connector
DP9600-L250: 250 mm L, -50 to 250°C
DP9600-H450: 350 mm L, -50 to 450°C
