“TESTERS” – Test Equipment to suit all deployed technologies

Customers who own infrastructure systems usually require some form of test equipment to assist with the build, operation and maintenance activities.

Given the mixture of old and new technologies now deployed, consequently the range of available test equipment options has grown considerably. And like the infrastructure systems themselves, new functionality demands and obsolescence issues also affect the associated test equipment needs and availability.

@YellowsBestLtd assists Customers by sourcing the required test equipment, supplying either modern or legacy units. Often refurbished ex-hire equipment in excellent condition and at commercially attractive prices makes sense over leasing. This ensures the continued availability of sets of the appropriate specification, which may become discontinued by the manufacturers over time.

If necessary, we can also arrange the repair of existing units, especially those that perform very specific functions that cannot easily be replicated with more recent equipment.

There follows a brief description of many of the types of test equipment available; we would be very keen to hear from you to understand your specific requirements, so please get in touch!

Calibration Checkboxes

Calibration checkboxes, or electrical checkboxes, are used for routine observations of test equipment and allow users to maintain accuracy in between official calibration procedures. Suitable for use with PAT testers and with other testers and instruments.
