Estimating measurement uncertainty is one of the most challenging tasks that scientists and calibration technicians have to deal with. When an instrument is calibrated the measurements should be traceable back to a common standard.
SRP control systems
The Isotech Isocal 6 Hyperion and Drago series introduced by SRP control systems are advanced liquid and dry block calibrators. Units have a temperature range from -25° to 250°C and six modes, including dry block and liquid bath.
This white paper discusses the basics of uncertainty in measurement and calibration. It is not made for mathematicians or metrology experts, but rather for those of you who are planning and making practical measurements and calibrations in industrial applications.
The model 761A pressure calibrator series from Additel measures up to 1,000 psi. Units feature removable internal pressure modules, optional precision models to 0.01%FS, increased speed to pressure, ability to read two external pressure modules, touch screen display, WiFi, Bluetooth, and Ethernet communications and double the original battery life.
The Additel 760 series automatic handheld pressure calibrator, available from SRP control systems, weighs less than 4 lb and contains a built-in pump, precision pressure sensor, internal controller and a large touch-screen color display.
The ProtEX-Pro PD6800 explosion-proof process meter from SRP control systems is said to bring modern design, easy readability, and enhanced functionality to hazardous areas around the world in a way never seen before.
There are many things you need to be aware before you can go to a hazardous (Ex) area to perform calibrations. There are different levels of hazardous areas and also different levels of calibration equipment.
