PARKER SERVICE JUNIOR SCJN-600-01 DIGITAL PRESSURE GAUGE SENSO CONTROL -1

The Parker Service Junior SCJN-600-01 is a robust, portable, and highly accurate digital pressure gauge designed for field service, maintenance, and calibration tasks. Part of Parker’s “Service Junior” line and manufactured by Senso Control (a Parker brand specializing in instrumentation), this device is known for its reliability, user-friendly interface, and compact design. It serves as a modern, digital replacement for mechanical test gauges.

Key Features & Benefits

• High Accuracy: Typically offers an accuracy of ±0.5% Full Scale (F.S.), providing reliable and precise measurements for critical service applications.

• Rugged and Portable: Features a robust, shock-resistant housing (IP54 rating) that protects it from dust and water splashes, making it ideal for use in harsh industrial environments. Its compact size allows it to be easily carried in a toolcase.

• Multiple Units & Zeroing: Allows users to switch between various pressure units (e.g., bar, psi, MPa, kg/cm²) at the touch of a button. It includes a “zero” function to tare out atmospheric pressure or offset for more accurate differential measurements.

• Peak Hold Function: This feature captures and holds the maximum (PEAK) or minimum (VALLEY) pressure reading during a test cycle. This is essential for diagnosing intermittent pressures or capturing pressure spikes that are difficult to see on an analog gauge.

• Backlit LCD Display: The large, easy-to-read digital display is backlit, ensuring clear visibility in poorly lit areas such as machine rooms or under equipment.

• Long Battery Life: Powered by standard, readily available AAA batteries, it provides long operational life, reducing downtime and maintenance costs.

• TARE Function: Similar to scales, the TARE function allows the user to reset the display to zero at any current pressure. This is useful for measuring relative pressure changes from a specific set point.
