The OM-CP-PRHTEMP101A is a low cost, state-of-theart
pressure, relative humidity and temperature data
logger, specifically designed to be compact and portable
for use in a variety of applications such as museum
and archive preservation, shipping and transportation,
warehouse monitoring, HVAC, clean rooms, clinical
laboratories and altitude validation and studies.
The OM-CP-PRHTEMP101A offers a 10-year battery
life, 1 second reading rate, multiple start/stop functions,
ultra-high speed download capability, optional memory
wrap, battery life indicator, optional password protection,
programmable high-low alarms and more.
Using the software, starting, stopping and downloading
from the OM-CP-PRHTEMP101A is simple and easy.
Graphical, tabular and summary data is provided for
analysis and data can be viewed in °C, °F, °R, K, for the
temperature channel, %RH, mg/mL and dew point for
the humidity channel, and mbar, PSI, inHg, mmHg, atm,
Torr, Pa, m, kPa, MPa for the pressure channel.
The OM-CP-PRHTEMP101A is a major leap forward in
both size and performance, Its real-time clock ensures
that all data is time and date stamped. The storage
medium is non-volatile memory, providing maximum
data security even if the battery becomes discharged.
Data retrieval is simple. Simply connect the data logger
to an available USB port and the easy to use Windows
software does the rest. The software converts your PC
into a real-time strip chart recorder. Data can be printed
in tabular format and can also be exported to a text or
Microsoft Excel file for further calculations.
The OM-CP-PRHTEMP101A was designed with our
customers in mind. There are free firmware upgrades
for the life of the product so that data loggers already
deployed in the field can grow with new technological
developments. Units do not need to be returned to the
factory for upgrades, this can be done automatically
from any PC.
