Description

The only pocket meter that directly measures nitrate ion and nitrate-nitrogen concentrations in 0.3ml sample (or 0.05ml sample with sampling sheet B). Unique sensor allows measurement of viscous liquids, solids, and even powder samples. No need for a beaker to calibrate your meter or measure a sample. Just place a few drops of the standard or sample onto the flat sensor. This procedure saves you time and prevents wasting your precious sample.

  • Minimum sample volume: 0.3ml (0.05ml with sampling sheet B)
  • Up to 2 calibration points
  • Auto standard recognition
  • Changeable high and low calibration values
  • Multiplication compensation: 0.01 to 9.90
  • Temperature and mV display
  • Temperature calibration: 5 to 40.0 ºC
  • Auto hold / auto stable measurement
  • Auto power off: 30 mins.
  • Low battery indicator
  • IP67 Rating dust & waterproof
  • Replaceable sensor
  • 400 Hours battery life: continuous use without backlight
  • Material: ABS epoxy
  • Display: custom (monochrome) digital LCD with backlight
  • Operating conditions: 5 to 40 ºC, 85% or less relative humidity
  • Warranty: 2 years – meter, 6 months – sensor
  • Packed in handy carrying case
  • Supplied with accessories (see specifications for more details)
