Below is some model-specific information to help you locate your instrument response.

Q330SR

The Q330 Standard Resolution datalogger has three or six channels recorded by a standard resolution (SR) ADC. Its preamp offers gains of 1 or 30.

Q330HR

The Q330 High Resolution datalogger has two sensor ports (QAPs) that are sampled by different ADCs. Port A (channels 1-3) is sampled by a high-resolution (HR) ADC with four times the number of counts/volt as the Q330SR (standard resolution) ADC. Port B (channels 4-6) is sampled by a standard resolution (SR) ADC identical to the ADC in the Q330SR with the same responses. The Q330HR preamp offers gains of 1 or 20.

Q330HRS

The Q330 Ultra High Resolution datalogger has six channels recorded by a high resolution ADC identical to the high resolution (HR) ADC in the Q330HR with the same responses. Its preamp offers gains of 1 or 20.

Q380

The x80 series dataloggers are named by the number of channels available (e.g. 380, 680) and share the same responses.

Q4120

The 4120 series dataloggers are named by the number of channels available (e.g. 4123, 4126) and share the same responses.
