The ERM-202 combines low noise circuitry with a high resolution stepper motor to achieve a PER dynamic range of 50 dB and angle resolution of 0.06°. It simultaneously measures PER, output power, and axis angle of the DUT. In addition, the dual channel version measures the power ratio of a device with two polarization maintaining (PM) outputs, such as a Y-branch fiber gyro IOC, PM coupler (PMC), or polarization beam splitter (PBS).

Our retarders are versatile and compatible with various concrete mixes. Whether you're working on residential, commercial, or industrial projects, our products offer consistent results.

The R-50 retarders are an alcohol based mixture that dries quickly and is used on the formwork of vertical concrete to help expose vertical surfaces.

Horizontal and Vertical retarders are designed to give you control over the amount of exposure the aggregate in the concrete will have.

Our set retarders are meant to be used with exposed aggregate mixes.  These mixes have specific aggregate properties which will enhance the look of the concrete.
