The DKY-01A is a handheld headspace gas analyzer for modified-atmosphere packaging. A standard electrochemical O2 sensor (optional NDIR CO2 sensor) measures residual O2 / CO2 inside sealed packages.
Its compact single-hand design, about 10-second readout and non-destructive sampling make it suited to production lines, warehouses and labs: monitor residual oxygen and gas ratio to optimise the process, extend shelf life and reduce spoilage complaints.
Features include a 3.5-inch industrial resistive touchscreen with one-touch operation, one-touch auto-calibration, auto power-off, a high-precision imported sensor and sampling pump, and automatic data storage with power-loss memory for up to 2000 records.
