The Graphtec GL2000 4-Channel True-RMS High-Speed Voltage and Temperature Data Logger allows for users to obtain voltage, temperature, humidity, logic, and pulse measurements simultaneously at high speeds. This logger is ideal for flow rate and temperature testing in water heaters, performing testing of inverters for air conditioners, thermal insulation performance measurement of residential housing units, and voltage or temperature measurement of generators.

The GL2000 is equipped with an isolated input mechanism to protect signals from interferences caused by noise from other channels. The 16-bit A/D converter has been adopted to achieve high-speed and high-resolution measurement. Able to obtain voltage, temperature, humidity, logic, and pulse measurements, this logger is also CAT III 600V compatible for measuring power supply circuits in equipment that captures power directly from the distribution panel. Abnormalities in a repeated waveform are measured by measuring the corresponding RMS value. The scaling function works by converting the measured voltage value to a specified engineering unit. Four arithmetic operations of addition, subtraction, multiplication, and division are available via two analog input channels. The trigger function includes level trigger of the input signal value for each channel. For each channel, the threshold for alarms can be set by the user.
