The 2620A is a Data Acquisition Unit ideal for applications that require direct connection to a PC for real-time data collection. An RS-232 serial interface makes it easy to connect the Hydra Data Acquisition Unit to a PC or modem for real-time data acquisition. The 2620A can also be used as a 20-channel panel meter.

The 2620A comes with a removable Universal Input Module that enables fast, convenient set-up and reconfiguration. Any combination of dc voltage, ac voltage, thermocouple, RTD, resistance, or frequency measurements can be connected to the input module without the need for additional signal conditioning. Thermocouple reference junction compensation is automatically performed by sensing the temperature of the input module's isothermal block.
