No matter the time of day or night, a Parameter service representative who is knowledgeable with the entire product line will be available to assist you. By asking just a few questions, the service representative can usually identify the problem and propose a solution. If a replacement part is required, most parts are kept in stock – some even covering units built over 40 years ago- and a shipment will be made by the fastest means available.

In those unusual instances where the problem cannot be resolved by phone, a trained Parameter field service representative will be sent to your site without hesitation.
