Selectra Inc. is a full line System Integrator. We work with our customers and their consultants to put the complete instrumentation package together. The Instrumentation Division of Selectra can supply a full line of instrumentation from all manufacturers to meet the needs of the customer. Selectra has a strong working relationship with many of the other System Integrators doing work in the Water and Waste Water market. When an outside Integrator is used the Instrumentation Division coordinates the installation and delivery of their equipment, and manages the flow of approval drawings. Selectra's field electricians, whether installing equipment supplied by us or an outside Integrator are experienced in the electrical installation and startup for most of the Instrumentation used in the Water and Waste Water Industry. Our Electrical Division is experienced in many wiring methods. Please refer to that part of this web for more details.
Selectra can take care of all of your Instrumentation calibration and startup needs. If your instrumentation can be site calibrated we can take care of that with our selection of calibration equipment, and where manufacturer re-calibration is required we can arrange that as well.
