3.2 Intended use
Application
The model CTR3000 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 CTR3000 is a high-accuracy instrument designed for laboratory and industrial temperature
measurement and calibration applications intended to be used in a basic electromagnetic
environment.
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 thermocouple types and NTC thermistors. The
following temperature measurement 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.
