Oakton Waterproof PC 450 Portable pH/mV/Conductivity/TDS/Salinity Meter with Combination Probe with NIST-Traceable calibration certificate

The PC 450 meter offers a rugged, waterproof housing, making it ideal for the manufacturing floor, field testing, as well as the laboratory. Large, back-lit LCD lets you view the main measurement simultaneously with temperature. Calibrate pH with up to six points from USA, NIST, DIN, and custom pH buffer sets. Auto-cal feature for conductivity has one calibration point per range. ATC ensures measurement accuracy even in fluctuating temperatures.

Meter features include ready (stability) indicator, smart averaging, user-selectable °C/°F units, hold function, calibration alarm, 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 cable for USB or RS-232 connectivity to transfer data to a PC.

  • Combination pH/conductivity/temperature probe
  • Intuitive, user-friendly icons — electrode status displays pH slope
  • Memory of 500 data sets and USB or RS-232 output for transfer to PC
  • Extended battery life or optional universal power adapter
  • Built-in stand with wall mount allows for easy bench-top measurement or storage
  • 3 year meter warranty
