Benchtop O2 / CO2 analyzer with built-in printer. Electrochemical O2 sensor as standard, optional NDIR CO2 sensor, readout in 6 seconds or less.
No additional images available.
The DKY-02A is a benchtop headspace gas analyzer. A high-precision electrochemical O2 sensor (optional NDIR CO2 sensor) and a sampling pump measure residual O2 / CO2 inside sealed bags, bottles and cans.
Its stable benchtop design with a built-in printer suits production lines, warehouses and QC labs that need fast, repeatable in-house verification.
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.
