Is it sufficient to send in my instruments for calibration every second year?

Currently I am using some measuring instruments like pressure calibrator, electrical calibrator and temperature calibrator. I don't know how to make my instruments reliable and after which time that are checked for calibration. Please give your suggestion.

You will have to take a look at how often they are used and decide, from the data from calibration if they are capable of holding their values over time. Selecting a date on a calendar isn't scientific and you will (potentially) be caught out by that...

Okay, what are the instrument models?
1. What is their current recall period / interval?
2. How many times have these instruments been sent out for calibration?
3. What was the as-found condition for each--in or out of tolerance?
