Portable, Low Cost NOMAD Dataloggers

PORTABLE, LOW COST NOMAD™ DATALOGGERS
For Temperature & Temperature/Humidity

OM-NOMAD
Compact Size
Programmable Limit Alarms with LED Indicator
Two-Year Battery Life
Stores Samples in Non-Volatile Memory
Software Available for DOS, Windows or Macintosh

The NOMAD Series Dataloggers are low-cost easy-to-use portable dataloggers which can record either temperature or temperature and humidity data. Because of its compact size, it is ideally suited for applications where space limitations exist. The NOMAD-T datalogger measures and records temperature only, using the internal temperature sensor or the optional remote sensor.

The NOMAD-RH Series Datalogger will measure and record both temperature and relative humidity simultaneously using the internal sensors. In addition to the temperature and humidity, the NOMAD datalogger will also store the unit identification number, start time, sample interval and descriptive text relating to the logging session. The NOMAD datalogger also features programmable alarm limits. If an alarm condition occurs, an on board LED will light when the pushbutton is pressed. Once collected, the data may be downloaded to a computer through a standard RS-232 connection using one of the three available software packages.

Software is available which will operate under DOS, Windows or on a Macintosh computer. Once downloaded to a computer, the data may then be stored on disk in a file format which is compatible with most spreadsheets. The Windows and Macintosh programs also provide graphic display and print out of the data.

Easy to use software provides clear graphs; data can be exported to any spreadsheet or database program for later analysis (Windows software shown).

The NOMAD datalogger is available with Windows or Macintosh software. Collected data may be stored in convenient spreadsheet format.
