Calibration technology
WIKA data sheet CT 60.15
Description
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.
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.
∙ 01/2017
Due to the wide range of this instrument it makes
individual instruments needless and makes the calibration
cost-eective.
Features included:
■
Dual capability for both thermocouple and resistance
thermometer measurements
■
Input channels can be expanded up to 44
■
Large graphic touchscreen for temperature measurement
values as well as conguration 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
