Reference Standard Meters Manufacturer and Supplier
Reference standard meters are the accuracy anchor of energy meter testing: a meter under test is compared against the reference, and the difference is the meter error. Field reference meters are portable and used on site; laboratory reference meters anchor bench testing.
The models grouped here are the reference meters named on the manufacturer's energy meter calibration category page. Selection depends on single-phase or three-phase use, the accuracy class required, and whether the meter must also test CT ratio and phase error. Before ordering, confirm the model, the accuracy class, the ranges, and the delivery terms.

Figures on this page come from the manufacturer's own category pages, manufacturer-hosted datasheets, or a shop listing stated as such. Where the reference material does not settle a figure, this site states that it is unresolved and publishes no figure, rather than choosing one.
What to confirm before ordering
Before payment, confirm the model, the specification from the current datasheet, the quantity, the price, the lead time, and the delivery terms, in writing. Ask in your inquiry to confirm the payment terms, the trade terms, and the reply time you should expect, rather than assuming any of them. No price, minimum order or lead time figure is stated on this site.
