Pressure and temperature checks often need two inputs, especially when comparing two points or tracking a difference. The HD2124.1 / HD2124.2 measures absolute, relative and differential pressure through PP471 modules with TP704 and TP705 probes, and measures temperature with Pt100 SICRAM or direct 4-wire Pt100 probes.
The two inputs can be used for two pressure probes, two temperature probes, or one pressure and one temperature probe. A-B calculation shows the difference between the two input channels, while Max, Min and Avg functions, REL, HOLD and pressure peak detection help users evaluate changing conditions directly on the large LCD display.
For documentation, the HD2124.2 stores up to 32,000 pairs of samples with configurable intervals from 1 s to 1 hour, then transfers data through RS232C or USB 2.0. IP66 protection, 200-hour battery autonomy and external 12 Vdc power support dependable portable and bench use.
Inputs A and B accept PP471 pressure modules or Pt100 temperature probes.
The instrument measures Pt100 probes with SICRAM module or direct 4-wire Pt100 probes.
The PP471 module acts as the interface between the instrument and TP704 or TP705 pressure probes.
The instrument displays the difference between the two pressure channels or the two temperature channels.
Max, Min, Avg, REL and HOLD functions are available during measurement.
Pressure peak detection is available for measurements made through PP471 pressure probes.
HD2124.2 records data and supports transfer by RS232C or USB 2.0.
Measurements can be transferred in real time through RS232C to a PC or portable printer.
