Model 4999

The Model 4999 Terminal Box allows instrument leads to be grouped in one convenient location, thereby saving time when readings have to be made on a number of instruments. Housed in a fiberglass enclosure, the Terminal Box provides a quick and easy means of taking sensor readings. The Terminal Box can handle up to sixteen 4-conductor sensors (e.g. 16 vibrating wire gauges with their thermistors) or thirty-two 2-conductor sensors (e.g. 32 vibrating wire gauges). Protection from lightning damage is provided by plasma surge arrestors and a suitable earth ground connection.
