About this item
These compact, portable meters measure dissolved oxygen and temperature using a smart optical sensor. Values are transmitted from and to the sensor in modified digital RS485 format. Ideal for field measurements.
- IP 67 waterproof housing, segmented LCD showing DO and temperature values simultaneously
- 50 or 250 data sets reviewable memory
- Sensor cap coefficients to be manually entered into instrument by end user; sensor cap change after 12 to 16 months
- 100 h battery life; low battery indicator; auto-shut off function (after 30 min of non use)
- Electrode offset recognition; auto-lock and hold of readings on display
Additional functions of DO 220 M:
- Extended memory capacity (250 data sets)
- Waterproof USB port for transferring data to a PC (no software required)
- Real time clock for saved data
- Recalibration reminder (selectable from 0 to 60 days)
Warranty: 3 years for instruments and 6 months for electrodes/probes/cables.
Delivery: Supplied in a carry case with optical DO sensor incl. 1 or 4 m cable.
