Portable Handheld Data Logger

OM-2041

U Input Signals: K, E, J, T, 0 to 5 V, and 0 to 20 mA

(Process Signals Need Input Adaptor)

U Simultaneous 4-Channel Measurement

and Display

U High/Low Alarms for Each Channel
U Computation: Maximum/Minimum/Average
U Logging Method: Log Mode and Tag Mode
U Data Processable Through a Personal Computer
U NEMA 3 Protection
U “AA” Battery Power Supply

The handy OM-2041 is a palm-size data logger capable of
storing up to 10,000 data records per channel. Powered
by either “AA” batteries or an AC adaptor, the OM-2041
works equally well as a portable or a fixed-location logger.

With the exclusive software, recording/recalling of data
and programming of logging parameters can be done
directly with the logger or through a personal computer.
