The OM-CP-PRHTEMP101A is a low cost, state-of-theartpressure, relative humidity and temperature datalogger, specifically designed to be compact and portablefor use in a variety of applications such as museumand archive preservation, shipping and transportation,warehouse monitoring, HVAC, clean rooms, clinicallaboratories and altitude validation and studies.
The OM-CP-PRHTEMP101A offers a 10-year batterylife, 1 second reading rate, multiple start/stop functions,ultra-high speed download capability, optional memorywrap, battery life indicator, optional password protection,programmable high-low alarms and more.
Using the software, starting, stopping and downloadingfrom the OM-CP-PRHTEMP101A is simple and easy.Graphical, tabular and summary data is provided foranalysis and data can be viewed in °C, °F, °R, K, for thetemperature channel, %RH, mg/mL and dew point forthe 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 inboth size and performance, Its real-time clock ensuresthat all data is time and date stamped. The storagemedium is non-volatile memory, providing maximumdata security even if the battery becomes discharged.
Data retrieval is simple. Simply connect the data loggerto an available USB port and the easy to use Windowssoftware does the rest. The software converts your PCinto a real-time strip chart recorder. Data can be printedin tabular format and can also be exported to a text orMicrosoft Excel file for further calculations.
The OM-CP-PRHTEMP101A was designed with ourcustomers in mind. There are free firmware upgradesfor the life of the product so that data loggers alreadydeployed in the field can grow with new technologicaldevelopments. Units do not need to be returned to thefactory for upgrades, this can be done automaticallyfrom any PC.
