9090 probes with sensor Pt 100 Ω are designed for temperature measurement in the range -20 et +150 °C for pH monitoring systems.
Built-in sensor is a Pt resistor, 100 Ω at 0 °C; probe is or simplex or duplex construction.
Probes 9090 are in conformity with standard DIN 43760.
They are used in particular on pH monitoring systems for automatic compensation of temperature.

The sensor is a Pt100 resistor, built-in a stem. The stem is fitted on a holder with its own PG 13.5 or with an additional pressure gland Ø 12 mm (not provided).
Connection: specific connector with a low contact resistance; the connector is molded on the cable to protect wires against humidity.
Connector is for shielded cable, 3 or 6 wires (0,22 mm²).
