PXF9 is an extremely compact temperature controller which has 96 x 96 mm front panel with a large, white LCD and 58mm depth behind panel.
Developed as a successor to the standard model PXR, PXF4 features fast sampling speed (50 ms) equal to PXH, highly accurate input indication, and universal input, in addition to various functions of PXG, while achieving a competitive price.
Equipped with multiple input/output and sophisticated control functions, PXF4 serves as a suitable temperature controller for a wide range of use.
FEATURES

500 ms)
•Improved input indication accuracy
For example: indication accuracy when measuring around 0.0°C by using type K thermocouple of which measuring range 0.0 to 400.0°C: ±1.1°C (cf. PXR: ±3.1°C)
•Freely configurable control cycle (100 ms to 99 s)
•Control method selectable among 7 types
(ON/OFF control, PID control, fuzzy PID control, selftuning control, PID2 control, 2-degrees-of-freedom PID control, motorized valve control (with position feedback input))
2.Any type of input can be accepted
•Universal input is supported (thermocouple, RTD, voltage, current)
