Multi-Functional Precision Thermometer

Application

The model CTR4000 precision thermometer provides a complete measurement and control interface for users wishing to make high-accuracy temperature measurements or calibrate thermometers. It supports a wide range of thermometer types, including 25 Ω SPRTs, 100 Ω PRTs, thermistors and thermocouples.

The CTR4000 is a high-accuracy measuring instrument designed for laboratory and industrial temperature measurements and calibration applications.

Functionality

The instrument will operate with all 3- and 4-wire (S)PRTs (25 Ω, 100 Ω) platinum resistance thermometers as well as most standard international thermocouples types and NTC thermistors. The following temperature measuring units are selectable: °C, °F, K. Base measuring units mV and Ω are also displayed. The temperature values will be calculated through common conversion of the base measurement.

Due to the wide range of this instrument it makes individual instruments needless and makes the calibration cost-effective.

The CTR4000 is offered in two versions: standard and advanced. The advanced version (CTR4000-A) has selectable excitation currents and standby currents for PRT probes. The advanced version also has increased measurement accuracy for PRT probes. The standard version (CTR4000-S) has fixed excitation current for PRT probes.

Features included:

• Excellent and high-accuracy measurement technology for the registration of different types of thermometers
• Large graphic touchscreen for temperature measurement values as well as configuration settings and statistical results
• Logger and log-data transfer to USB stick or communication interface
• Scan function with a live screen and graph
• Communication interfaces available for automated monitoring and calibration applications
