Multi-functional precision thermometer,
model CTR3000
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

will be displayed on the right section and can easily be
chosen.
In the menu setting all things concerning the instrument can
be handled.
In this menu the probe settings can be selected and the
reference thermometers can be stored under a unique name.

With DIN plug or SMART plug
With ASL's SMART connector on the probes, storing the data
is needed only once - in the connector! The calibration data
stays with the probe - permanently. It can even be used on
another instrument without any further action.
The SMART connector saves time and reduces error.
If there are existing calibrated or uncalibrated probes, no
problem, CTR3000 automatically registers if a probe is
SMART or normal.

We are expanding our product range of precision
thermometers to a versatile thermometer for the industrial
market with the model CTR3000 multi-functional
precision thermometer. The ability to measure resistance
thermometers, thermocouples and thermistors up to 44
pieces at one time, makes the instrument versatile.

Resistance thermometer measurement
The CTR3000 is new in its class. The instrument closes
the gap between the hand-held series CTH6x00 which can
handle thermocouples and the desktop instrument like model
CTR5000 which can only handle resistance thermometers.

TC and PRT measurement
It is a precision instrument, designed for use in a laboratory
or light industrial environment. The instrument can be
extended by using scanner boxes to gain additional
channels.

The instrument model CTR3000 is compatible with the
existing model CTS5000 scanner box for resistance
thermometers. In addition, the user interface is easy to
handle like other WIKA calibration technology products.
