The GP1 is a high accuracy 7 channel data logger. It can record data from 2 differential analog sensors, 2 temperature sensors (or 2 further single-ended analog sensors), 2 pulse counters and one Delta-T WET Sensor.

The GP1 offers a solution in a box, including: PC software, to program the logger and view and analyze data; a serial RS-232 cable, to connect to a PC; and a full-color printed guide that outlines how to connect sensors, how to use the software, and how to get up and running quickly.

An IP67, environmentally sealed weatherproof enclosure is included. The GP1 has an internal battery and extremely low power consumption. The 9V alkaline battery (provided) will typically last over one year, with 3 years typical for a lithium battery. This means low maintenance, without the need or expense of a solar panel or rechargeable batteries.

The GP1 can power sensors with configurable warm-up time prior to taking readings. Both switched power and a switched +5V reference is available for sensor powering.
