OMEGA’s DP251 precision RTD thermometer can be used as a single probe laboratory instrument, a portable site standard or as a permanently wired multi-channel scanning system. RTD probes can be connected either to front panel DIN sockets or rear panel screw terminal plugs. Probe input A or B, differential display (A-B), zero, resolution and readout units are front panel selectable. The Run/Cal key-operated switch selects the measurement (Run) or data entry (Cal) modes.

DP251-SOFT LabWindows software is a PC compatible data acquisition package that uses a virtual front panel display to represent the DP251 on your monitor. The software controls all of the DP251 functions, plus those of the DP250-8 and DP250-16 multiplexers when used with a system. A time vs. temperature screen incorporated into the virtual front panel allows you to plot temperature trends.

Like the DP251, the DP252 is a precision RTD thermometer and also an RH and dew point indicator when used with the DP250-SP standards psychrometer. The DP250-SP psychrometer uses a low power fan to draw air across two traceable calibrated platinum RTD’s housed in a flow chamber to measure wet and dry bulb temperatures.
