WD-35618-34 pH 450 Portable Waterproof pH Meter with NIST Certificate by Oakton

The pH 450 meter offers an IP67-rated waterproof housing, making it ideal for the manufacturing floor, field testing, and the laboratory. The large, backlit LCD lets you view the main measurement simultaneously with temperature and calibration data with % slope. Calibrate pH and ISE with up to six points from USA, NIST, DIN, PWB and custom pH buffers. Automatic temperature compensation (ATC) ensures measurement accuracy even in fluctuating temperatures. Select temperature reading from degree C or degree F to suit your application.

Meter features include ready (stability) indicator, smart averaging, hold function, calibration alarm (visible), battery-life indicator, and electrode status.

Perform data logging with manual or timed collection of up to 500 data sets with real-time clock time/date stamp. Order optional data cables for USB or RS-232 connectivity.

• Intuitive, user-friendly icons--electrode status displays pH slope
• Grip-Clip electrode holder quickly and easily secures electrode to side of beaker or container
• USB or RS-232 output for up to 500 data sets
• Extended battery life or optional universal power adapter

WD-35643-13 DO 6+ Dissolved Oxygen Meter with Probe, with NIST Traceable Certificate of Calibration, 0.0 to 50.0°C Tempature Range and 0.0 to 50.0 ppt, 0 to 20 mg/L Dissolved Oxygen Range by Oakton

High accuracy combined with economical pricing

These meters provide a great value. The ranges work to test water quality in wastewater, surface water, ground water, or drinking water. A clear LCD display shows results in ppm or mg/L with enunciators to aid in use and troubleshooting. Six simple buttons allow for freezing readings, toggling between display units and temperature results, setup, calibration, and automatic barometric and salinity compensation after manual parameter inputs. Additional benefits of the simple design allow you to view electrode slope, zero offset, and millivolt values for electrode diagnostics.

• Includes Galvanic dissolved oxygen probe, electrolyte solution, membrane caps,protective rubber boot, and batteries
• Low-maintenance, Galvanic probe requires no warm-up time
