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. 

**K-1** 

**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 

## **Specifications** 

## **Inputs/Ranges/Sensors** 

**Type:** Pt100 to IEC 751 (ITS 90 refers) -200 to 850ºC (-328 to 1562ºF) Ro = 100 Ω 3- or 4-wire connection with automatic recognition (with manual override) 

**Overall Accuracy:** ±0.01ºC ±0.0005% of span 

**Linearisation Conformity:** Better than ±0.01ºC 

**Stability (vs Ambient Temperature):** Better than 0.0025ºC per 1ºC ambient change 

**Warm-Up:** Negligible under normal ambient conditions. Allow 5 to 10 minutes for full stability unless stored at low temperature, then 30 minutes minimum 

**Pt100 Sensor Current:** 0.5 mA 

**Resolution of Data Display:** 0.01 

**Variable Filter:** Sampling rate selectable between 4 and 64 (measurements averaged per reading) 

**Measurement Units:** °C, °F, K, Ω 

**Measurement Modes:** A, B or A-B 

**Custom Calibration:** Up to 10 calibration values can be allocated to Pt100 input A & 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 connector 

**Null Function:** Corrects differential temperature readout between two sensors to zero 

**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) approximately 

**Input Connections:** 2 x Pt100 via D type connectors **USB Serial:** Isolated, 38400 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 1 Vdc _**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 instrument must therefore be isolated from high voltage pick-up._ 

**Precision Pt100 Probes:** 304 Stainless steel probes, 6 mm diameter with 2 m (6.6') screened PTFE lead Pt100 Probes and connector 

**DP9600-L250:** 250 mm (9.85") L, -50 to 250ºC (-58 to 482ºF)
