SN500SS
OrderableNet Radiometer
Overview
This four-component net radiometer, manufactured by Apogee Instruments, provides individual measurement of net radiation components. This sensor features an SDI-12 output, eliminating the need for multiple analog channels to measure the individual components of net radiation. The SN500SS offers a complete package that includes a net radiometer, mounting rod, pigtail lead cable for data logger interface, and a carrying case.

(5)32295
Sensor Mounting Kit for the SN500SS Net Radiometer
One 32295 mounting kit is needed per SN500SS sensor. The 32295 was designed to fit the mounting rod that comes with the net radiometer. The mounting bracket can be mounted to a mast or pipe.
Orderable39115
DIN Rail Terminal Kit with 2 Terminals and 4 Wires
The 39115 provides the needed DIN rail terminals, separator, and wires to connect any product to a data logger or other peripheral that requires four wires for connection. This kit provides the following wires: black, red, white, and clear. The color-coding of these wires matches the wire coloring of the product for ease in connection, maintenance, and troubleshooting.
Orderable39642
SDI-12 DIN Rail Terminal Bus Kit without Mounting Bracket
The 39642 makes it easier for you to connect wires from multiple SDI-12 sensors into one set of terminals on a data logger. The 39642 uses six DIN-rail mountable (pn 27479), 6-wire terminal blocks. The 39642 is a jumper that electrically connects two terminal blocks together at a time (pn 32918). This setup allows up to 11 SDI-12 sensors to be connected to one set of terminals on a data logger.
OrderableCABLE6PIN-LITE
26 AWG Three-Conductor Cable with M8 Six-Pin V-Coded Pin (Male) Connector
The CABLE6PIN-LITE is a cable assembly with an M8 six-pin V-coded connector on one end and flying leads on the other end. Three of the pins and the shield are presented as flying leads with ferrules. The six-pin connector is weatherproof and suitable for harsh environmental conditions.
OrderableCABLE6T8PIN
26 AWG Six-Conductor Cable with M8 Six-Pin V-Coded Pin (Male) Connector to M12 Eight-Pin A-Coded Pin (Male) Connector
The CABLE6T8PIN is a cable assembly with an M8 six-pin V-coded connector on one end and an M12 eight-pin A-coded connector on the other end. This cable features a durable thermoplastic rubber (TPR) jacket engineered to withstand extreme temperatures (-40° to +80°C), resist UV exposure, and perform reliably in marine and corrosive environments. The six-pin and eight-pin connectors are weatherproof and suitable for harsh environmental conditions.
