Individual Sensor Boards (ISBs) have been built with lowest noise for the new B4 family of sensors, designed where best resolution at low ppb levels is required in permanent fixed site networks. Requiring 3.5 to 6.4 VDC input, they provide buffered voltage output from both the working and auxiliary electrodes. Boards are pre-configured when you order for the type of sensor, with fixed zero and electronic gain. Each ISB supports one B4 sensor and requires less than 1.5 mA power.
