Description
The model CTR2000 precision thermometer comprises two
measurement versions: One version accepts only 4-wire
PRTs, the other version accepts both 3- and 4-wire PRTs.
The high-performance 2- or 8-channel, 3- and 4-wire
precision digital thermometers is suitable for use with
calibrated and uncalibrated Pt100 probes. It is characterised
by its extended features for high usability and low life costs.
Using calibrated probes with the CTR2000 thermometer
series choose between storing calibration data into memory
in the instrument or into the probe’s proprietary SMART
connector. Calibration data stays permanently with the
probe in this connector, which the CTR2000 series instantly
recognises, ensuring best measurement accuracy.
Precision thermometer, model CTR2000
Using a built-in calibration routine, the CTR2000 instrument
range can be recalibrated using a calibrated, traceable
reference resistor. This feature is password protected.
Other features have been included for CTR2000 range when
using SMART probes, like the temperature watchdog and the
calibration status monitor.
The temperature watchdog continuously monitors the
temperature of SMART probes and, if any are used outside
their specied working range, the probe history record is
updated.
With this way, it can be seen at a glance if the probes have
ever been used outside their calibrated range, as this may
aect their calibration validity. The calibration status monitor
alerts with an on-screen message when a SMART probe is
due for recalibration.
