measurement
2635T
The Fluke 2635T and 2620T
Recording Thermometers are precision multi-channel temperature recording and logging instruments
that deliver up to 0.1°C accuracy
(3 sigma, one year accuracy specification*) for temperature monitoring
and calibration applications. Based
on Fluke’s 20 channel Hydra Series
Ordering Information
2620T: Recording thermometer with
Probe and Hydra Logger Software
2635T: Recording thermometer with
Probe, Hydra Logger Software, and
256K PC memory card
2600A-101: EXTRA SPRT probe, 100
Ohm PT, Probe with soft case only
2600A-904: TrendLink Software
II data loggers, these units
are matched with a precision SPRT
probe (RTD) on channel one and
calibrated as a system for maximum
accuracy and precision. Calibrations
are NIST traceable and DKD certified. Each unit is delivered with
current calibration data, ready for
use. Hydra Logger Software is also
included with each unit for support
of basic data collection and easy
instrument configuration. Optional
TrendLink for Fluke trending software is also available for electronic
chart recording display an analysis.
In addition to being a precision thermometer, both models are capable
of measuring up to 18 additional
channels of thermocouple, dc and ac
volts, frequency, and 2-wire Ohms.
A total for 10 RTD probes can be
connected and recorded at one time.
