AOIP PHP 602 High Accurate Dual Input Reference Thermometer For RTDs


  • Temperature measurements using RTDs
  • Absolute or differential measurements over two channels
  • Differential thermal analysis
  • Checking the temperature stability of furnaces or baths
    • Monitoring (alarm) and temperature recording

AOIP PHP 602 is a highly accurate thermometer with dual inputs for resistive probes. It already contains a large database of probe information. In addition, users can create new linearization tables at any time, and all metrological parameters, including corrections against standards, serial numbers, names, and calibration dates, are stored in the memory. When paired with VISULOG data management software, AOIP CALYS 100 can control PHP thermometers and thermal devices like temperature baths, dry block calibrators, or ovens. This allows for complete calibration procedures, report generation, and printing certificates for each sensor.

The graphical dual display of AOIP CALYS 100 shows measurements from both channel 1 and 2 at the same time, making the keyboard easier to use. Users can access on-line help messages anytime for extra guidance on displayed options. It’s fully programmable through RS 232 and IEEE 488 interfaces (optional), making it ideal for test benches and automatic test equipment setups. PHP 601 comes with an optional battery. PHP 602 is available in a compact benchtop design for on-site, benchtop, or panel-mounted use. It is widely used in metrological departments, quality control, research labs, and maintenance and certification companies.
