DP9601 shown smaller than actual size.

The DP9601 provides precise platinum resistance thermometer temperature measurement and logging for exacting 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. 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, K, Ω 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 two input ports for 3- or 4-wire Pt100 sensors; the instrument automatically recognizes 3- or 4-wire conﬁgurations. The measured temperature can be displayed directly from one of the inputs or differentially between the two inputs. Differential temperature and the two individual channel temperatures are displayed simultaneously.

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.

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 character OLED screen 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

(7.5 x 2.75 x 9.85")

Weight: 3 kg (6.61 lb) approx Input Connections: 2 x Pt100 via D type connectors USB Serial: Isolated, 9600 Baud, 8 data, no parity,

1 stop bit

Communications: 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

Analog Output (Standard): User programmable, 0 to 5V

Application Note: Inputs are not isolated in the instrument, which is primarily designed for laboratory applications and site calibration of industrial temperature sensors. Probes connected to the instrumentmust therefore be isolated from high voltage pick-up.
