Hello Ben, thank you for visiting our forum today.
Yes we carry the EXTECH brand of Process Calibrator. They can be ordered 2 different ways with or without the NIST certificate.
EXAMPLE; The 412355A is a current and voltage source instrument without certificate.
The 412355S-NIST will be factory calibrated to NIST standards and supplied with the certificate.
You can reach us 800-521-1615 and ask for sales.
Thanks again for visiting us at Galco.com
Hi Ted, be happy to answer your question.
Process calibrators are an instrument that can supply a signal current like 4-20ma or a signal voltage like 0-10volt with great accuracy if factory calibrated to NIST standards. They are generally used to setup and test control systems like drives, process controllers with PID loops etc.
