Temperature/Humidity
Logger
- Measure temperature and humidity
with one instrument
- Accepts two type J, K,or T thermocouple
probes
- Standby mode conserves batteries
while logging data
- Optional software for bidirectional
RS-232 communications
- Stores 850 pairs of measurements
Use the benchtop Temperature/Humidity
Logger almost anywhere
temperature and humidity needs to be monitored - laboratories,
museums, art galleries, warehouses, protected outdoor
environments, and more! The logger operates in three modes:
two-channel temperature, humidity/temperature, and dew
point/temperature.
This compact, portable Temperature/Humidity
Logger is packed with features.
Nonvolatile memory stores setup conditions (interval time
or total logging time), thermocouple probe type, logged/stored
parameters, and peak/valley values for each mode. Serial
input/output allows for printer and computer compatibility,
Optional data analysis software and serial printer available.
Measure and display either differential
(DT) temperature or dual temperature simultaneously in
the two-channel temperature mode. The temperature
/ humidity logger accepts
one or two type J, K, or T thermocouple probes with ANSI
miniconnectors. Features in this mode include autocalibration
of probe, selectable °F or °C scale, selectable
0.1%/1° resolution up to 999.9° (1° above
999.9°), dual analog temperature output, and accuracy
of ±0.1% of reading.
Measure and display both relative
humidity and temperature (RTD) in the humidity/temperature
mode. Use one of two interchangeable relative humidity/temperature
probes. Wide-range probe 637-0050 has a compensated RH
range from 0 to 100%. General-purpose probe 637-0052 has
a compensated RH range from 5.0 to 95.0%. Other features
in this mode include: automatic field calibration, a humidity
resolution of 0.1% and 1% and analog humidity/RTD outputs.
In the dew point/temperature mode,
temperature / humidity
logger calculates the dew
point from the relative humidity and temperature data,
and displays it and the temperature (RTD) on the LCD.
A dew point range of -94° to 158°F (-70° to
70°C) is available with wide-range humidity probe
637-0050, a dew point range of -58° to 122°F (-50°
to 50°C) is available with general-purpose humidity
probe 637-0052.
The Temperature/Humidity
Logger is housed in a molded
ABS plastic housing and has a membrane keypad. Dual LCD
shows scale and mode selected. Two AA batteries (included)
provide 50 hours of continuous operation in standby mode.
Purchase optional battery pack for up to 300 hours of
continuous use. (We recommend using the optional AC wall
mount power supply 691-9050 where line power is available).
Order the L-shaped mounting bracket to attach either RH
probe to the logger. See below to order software, logger
kits, probes, and accessories.
