high precision thermometer PHP 601
Main applications include:
•Temperature measurements using RTDs and/or thermocouples
•Absolute or differential measurements over two channels.
•Differential thermal analysis.
•Checking the temperature stability of furnaces or baths.
•Monitoring (alarm) and temperature recording.

RS 232 or IEEE 488 interfaces
The PHP 601 is a high accuracy, dual input thermometer suitable for use with RTDs (e.g.: Pt 100) and thermocouples.
The PHP 601 is capable of storing sensor characteristics and coefficients and can scan up to 12 sensors using the model SHP 101 Scanner.
Its main applications include the calibra- tion of temperature sensors. By using our CAL'EXPERT software to drive the
PHP 601 thermometer, scanner and a ther- mal device such as temperature bath, dry block calibrator or oven, a complete cali- bration procedure can be performed, reports generated and certificates printed for individual sensors.
