PHP 602 is a high accurate dual input reference thermometer for resistive probes.
A large number of probes already exists in the instrument data base. In addition, the user can at anytime create new linearisation tables and the metrological parameters (correction versus standards, serial numbers, names, calibration dates ...) are stored in the memory.
Used together with VISULOG data management software to drive PHP thermometer 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 602 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.
Applications:
- 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
Specifications and performances in temperature @23°C ±1°C
Uncertainty is given in % of reading (PHP 601 display) + fixed value.
