Test reports are automatically generated in two convenient formats, PDF and XLSX.

The PIT5000 will pay for itself many times over by reducing time for set-up, tear-down and eliminating tedious, error prone manual data collection. In addition the real-time graphs allow you to see exactly what is happening, and focus on what is important, during the entire test process

Control valves are valves used to control conditions such as flow, pressure, temperature, and liquid level by fully or partially opening or closing in response to signals received from controllers that compare a setpoint to a process variable whose value is provided by sensors that monitor changes in such conditions.Control Valve is also termed as the Final Control Element.

The opening or closing of control valves is usually done automatically by electrical, hydraulic or pneumatic actuators. Positioners are used to control the opening or closing of the actuator based on electric, or pneumatic signals. These control signals, traditionally based on 3-15psi (0.2-1.0bar), more common now are 4-20mA signals for industry, 0-10V for HVAC systems, and the introduction of Smart systems, HART, Fieldbus Foundation, and Profibus being the more common protocols. Some of the control valve available are Reverse Double-Ported Globe-Style Valve Body, Three-Way Valve with Balanced Valve Plug, Flanged Angle-style control valve body and . Valve Body with Cage-Style Trim, Balanced Valve Plug, and Soft Seat.

The Model 20DAX40 manometer is designed for the measurement of pressures, vacuums or differential pressures with a maximum operating pressure of 400 PSI. This manometer is of very rigid construction, designed primarily for high line pressure operation. Only carefully selected, fully annealed glass tubing is used. The manometer scale is located to permit quick and accurate reading of the indicating columns. The U-tube type manometer is a primary basic standard of pressure measurement. Pressure measurements are accomplished by balancing a vertical head of indicating fluid with the pressure to be measured. As there are no cams, gears or levers to operate in the manometer; the readings obtained are accurate.
