HD 2304 — portable pressure and temperature system

• Pressure: 10mbar...+500 bar • Temperature: -200...+650°C • Gauge, absolute and differential pressure • Minimum, maximum and average values • High accuracy Portable system for measuring pressure and temperature in industrial activities such as energy, construction and manufacturing. The HD 2304 is a portable instrument with an LCD display, supplied as the housing alone. It measures absolute, gauge and differential pressure as well as temperature. The HPP 471 electronic module is used to measure pressure (supplied) and acts as an interface between the instrument and the HTP 704 and HTP 705 probes. Temperature is sensed with Pt 100 immersion, penetration, contact or air probes. The temperature probes carry an automatic recognition module; the factory calibration data is stored inside. On power-up, the instrument detects them automatically. The Max, Min and Avg functions compute the maximum, minimum or average values. The other functions include relative measurement REL, the HOLD function and automatic switch-off.
