COMET D0211
Single-Channel Ni1000 / Pt1000 Thermometer with Data Logger
Reference: D0211
Professional portable thermometer for temperature measurement and data logging using an external Pt1000 or Ni1000 probe, featuring non-volatile internal memory, backlit LCD, acoustic indication and USB data transfer to a PC.
1 Channel – external temperature probe input
Pt1000 / Ni1000 – compatible with external RTD probes
-200 to +500 °C – measuring range with Pt1000
16,000 Values – non-volatile internal memory
10 s to 24 h – adjustable logging interval
COMET Vision – analytical software included
Measured values can be stored in the internal non-volatile memory, allowing temperature conditions to be monitored over extended periods and subsequently transferred to a computer for analysis and documentation.
The D0211 is suitable for laboratories, quality control, industry, maintenance, storage, HVAC, research and technical monitoring, combining portable measurement with data logging capability.
Important: External Probe Not Included
The COMET D0211 requires a compatible external Pt1000 or Ni1000 temperature probe for measurement. The temperature probe is not included in the standard delivery and must be selected separately according to the temperature range, application, probe design and cable length required.
Why Choose the COMET D0211?
Measurement + Data Logging: combines portable temperature measurement with automatic data recording.
Pt1000 / Ni1000: select the external probe best suited to the application.
Internal Memory: capacity for approximately 16,000 values.
Adjustable Logging: interval from 10 seconds to 24 hours.
Acoustic Indication: supports monitoring of configured conditions.
Backlit LCD: clear measurement display in the field.
USB + COMET Vision: transfer and analyse recorded data on a PC.
Temperature Measurement with External Pt1000 or Ni1000 Probe
The D0211 uses an external RTD probe, enabling the sensor and probe construction to be selected according to the specific application.
With a suitable Pt1000 probe, the instrument supports a measuring range of -200 to +500 °C, subject to the permissible range of the connected probe.
The D0211 can also be configured for Ni1000/6180 ppm sensors, providing additional flexibility for compatible temperature probes.
Temperature Data Logger with Internal Memory
In addition to instantaneous measurement, the COMET D0211 can automatically record temperature in its non-volatile internal memory.
The logging interval is adjustable from 10 seconds to 24 hours, allowing the instrument to be adapted to both shorter processes and long-term monitoring.
Cyclic and non-cyclic recording modes are available. In non-cyclic mode, logging stops when the memory is full. In cyclic mode, the oldest stored data is overwritten by new measurements.
USB Data Transfer and COMET Vision Software
Recorded data can be transferred to a computer using the included Mini USB cable for subsequent analysis, visualisation and documentation.
The standard delivery includes the free full version of COMET Vision, analytical software designed for COMET data loggers and monitoring instruments.
Important: the USB connection is intended for transferring stored data. Measurement and data logging are not enabled while the instrument is connected to the PC.
