Perfect for conditions that ruin ordinary dissolved oxygen meters! This completely waterproof meter reads dissolved oxygen in mg/L, ppm or % saturation. Its waterproof construction lets you thoroughly wash the meter to maintain working condition.

This meter does the work for you. It automatically calculates barometric pressure and salinity offset values and it guarantees high accuracy with independent 100%, zero, and offset adjustment capabilities.

• No meter warm-up required - take DO measurements right away
• Low maintenance galvanic probe comes with 10 ft length cable
• Memory stores and recalls up to 50 readings plus temperature
• Real-time clock stamps stored data and calibration data with date and time
• Key in salinity and pressure manually; meter automatically calculates offset values
• Dual display shows mg/L (ppm) or % saturation plus temperature (°C/°F selectable)
• Hold function, Ready indicator, automatic shutoff
• Iincludes an easy-to-service dissolved oxygen/temperature probe, replacement membrane cap, electrolyte solution, and batteries
