High Accurate Dual Input Reference Thermometer For RTDs And Thermocouples – AOIP PHP 601


  • 2 alarms with sound signal and relay output (1 A, 220 V~, 60 VA max)
  • A programmable digital filter enables the PJ 6301 to display a smoothed value taking into account previous measurements.
  • Continuous display of average, minimum and maximum value of the signal under monitoring, as well as number of measurements.

PHP 601 is a high accurate dual input reference thermometer for resistive probes and thermocouples. It is able to store sensor characteristics and coefficients and can scan up to 12 sensors using SHP 101 scanner, without any loss of signal integrity or performance. Used together with VISULOG data management software to drive PHP thermometer, SHP 601 scanner and a thermal device such as temperature bath, dry block calibrator or oven, a complete calibration procedure can be performed, reports generated and certificates printed for individual sensors.

Its graphical dual display enables measured values from channel 1 and 2 to be simultaneously displayed and leads to keyboard simplification. On-line help messages are available at any time in case additional information on displayed options is needed. It is fully programmable via RS 232 and IEEE 488 (option) interfaces, which makes it the perfect instrument for test benches and automatic test equipment applications. PHP 601 is also available with a battery in option. PHP 601 is offered into a compact benchtop housing for on-site use as well as benchtop or panel mounted use. It is widely used in metrological departments, quality-control departments, research and development laboratories and also by maintenance and approval companies.
