High accuracy scanner SHP 101 - AOIP - #1

The SHP 101 bench top instrument is capable of scanning up to 12 temperature sensors. When used with the Precision Thermometer P-P 601, thermocouples and RIDs can be measured without loss of signal integity or performance. Each bock may be configured either as two measurement channels (thermocouple or voltage measurements) or as a 4 wire measurement (RIDs).

- Programming and processing by using the 12-key keypad, RS 232 link or option­al IEEE 488 link.

- Connection of the sensors by means of screw terminals accepting 4-nm plugs (tel­lurium copper terminals with extremely

- Switching of resistance in 3 or 4 wire configuration.

- Switching of thermocouples with or with­out reference junction compensation.

- Outputs available for direct link to the high accuracy thermometer PHP 601.

The SHP 101 operates as follows: -Manually by using the front keypad. -Remote controlled either by a PHP601 (direct RS 232 command) or a controller (RS 232 or IEEE interfaces).
