The DP9601 high-precision digital RTD thermometer/data logger provides exceptional platinum resistance thermometer temperature measurement and logging for demanding laboratory and field applications. It is an extremely accurate and stable digital thermometer, particularly suitable for use with thermal calibration baths as a reference standard. Applications include medical, pharmaceutical, food, environmental testing, R&D, and educational institutions. Displayed values and user information appear on a bright LED screen with diffused backlight. Data can be displayed in °C, °F, K, and ohms as desired; nine front panel keys provide intuitive user controls used in conjunction with the display. This arrangement makes operation extremely simple and “user-friendly.” There are two input ports for 3-wire or 4-wire Pt100 sensors; the instrument automatically recognizes 3-wire or 4-wire configuration. Measured temperatures can be displayed directly from one input, or differential readings can be displayed between the two inputs. Differential temperature and both individual channel temperatures are displayed simultaneously. A flash drive USB port is provided to allow data storage and/or export. PC software running in Windows® is standard; it allows programmable custom calibration, remote control, and measurement and recording functions.

Overall Accuracy: ±0.01°C ±0.0005% of span

Linear Conformity: Better than ±0.01°C

Stability (vs. ambient temperature): Better than 0.0025°C per 1°C ambient change

Warm-up: Negligible under normal ambient conditions; 5 to 10 minutes required for full stabilization unless stored at low temperature, then at least 30 minutes

Pt100 Sensor Current: 0.5 mA

Data Display Resolution: 0.01

Variable Filter: Sampling rate selectable from 4 to 64 (average measurements per reading)

Measurement Units: °C, °F, K, Ω

Measurement Mode: A, B, or A-B

Custom Calibration: Up to 10 calibration values can be assigned to Pt100 inputs A and B. Values are retained in non-volatile memory until replaced by user; ITS 90 or IPTS 68 coefficients can be used for custom calibration

Smart Sensor Connection: Correction values stored in the connector

Front Panel Controls: 9 membrane keys to control all instrument functions

Mechanical/Housing: Metal desktop housing / adjustable tilt

Dimensions: 190 W × 70 H × 250 mm D (7.5 × 2.75 × 9.85")

Weight: Approximately 3 kg (6.61 lb)

Input Connections: 2 × Pt100 via D-type connector

USB Serial: Isolated, 38400 baud, 8 data, no parity, 1 stop bit; remote control and measurement

PC Software (standard): Provided as standard on CD-ROM; remote control and measurement; record readings to file / download to PC / program corrections

Analog Output (standard): User-programmable, 0 to 1 Vdc

Application Note: Inputs are not isolated within the instrument; primarily intended for laboratory applications and field calibration of industrial temperature sensors. Therefore, probes connected to the instrument must be isolated from high voltage pickups.
