• User-replaceable cables and sensors provide versatility, reduce down time and reduce overall cost of ownership.
• Available with 1- 4- 10- 20- and 30-m cable lengths standard (cable management kit included on all cables 4-m and longer).
• Smart calibration; the instrument remembers the previous calibration values and simply walks you through the routine (quick DO cal with the push of 2 buttons).
• Stores 50 data sets; no need to write down data.
• Large graphic, backlit display and glow in the dark keypad. Usable in any lighting condition. The display is also visible when wearing polarized sunglasses.
• Tough. IP67, impact-resistant, waterproof case. Waterproof without the battery cover as well.
• Rubber over molded case provides extra durability. Military spec connectors are unsurpassed for ruggedness.
