  • Description

    THE CALBOX

    The CalBox Calibration Checker is a simple way to ensure the on-going accuracy of electrical test equipment between dates of calibration. This means that you can produce a record of instrument accuracy to your regulatory assessor (NICEIC, NAPIT, ELECSA, ECA) in order to comply with the assessment procedures that they have in place. It also gives you, the user, peace of mind that your test instrument is giving you accurate readings between its annual calibration.

    The unit is easy to use – simply plug your tester (analogue or digital) into the CalBox to prove accuracy of both continuity (0.5, 1 & 2 Ohms) and insulation resistance (0.5, 2 & 200M Ω. Checking RCD and loop test accuracy of your instrument can be conducted at a dedicated labelled socket at your premises (bench mark circuit), making the CalBox a valuable accessory to carry within your toolbox.

    The CalBox calibration checker is built with high quality resistors which can be tested at 1000V DC and are manufactured to produce an accuracy within 2%. The Cal Box also utilises universal 4mm socket connectors, enabling use with any brand of test equipment that you own.

    Hi, I bought one of your Cal Box calibration checkers a few weeks ago prior to an external audit and its been worth every penny. We have six insulation testers in the company, three of them were 2nd hand bought cheap of an auction site and the others range in age from 6 years to about 2 years. Guess what? Two of the 3 cheap ones from the auction site were well out of specification so we hid them! If the inspector had checked them we might have failed but luckily we passed :) Not sure whether to bin them or put them back on eBay!! Considering the Cal Box cost ,its really well built, light and compact and arrived next day.
