Features:
- User-replaceable cables and sensors (pH, ORP, Polarographic DO, Galvanic DO)
- Smart calibration
- Military spec connectors, IP-67 waterproofing, and 1-meter drop tested
- Rubber over-molded case
- Low total cost of ownership
- Stores 50 data sets
- Graphic, backlit display and glow-in-the-dark keypad visible with polarized sunglasses on
- Available with 1, 4, 10, 20, and 30-m cable lengths standard
